In an effort to reduce respiratory illnesses, the local government of Oakhaven subsidized the installation of advanced air-purification systems in homes. These systems have been scientifically proven to eliminate 99 percent of common indoor allergens, such as dust mites and pet dander. Within a year, the majority of Oakhaven households had installed the systems. Nevertheless, public health records indicate that the total number of severe asthma attacks in Oakhaven actually increased over that same year.

Which one of the following, if true, most helps to resolve the apparent discrepancy?

Cevabı ve açıklamayı göster

Cevap: The advanced air-purification systems drastically reduce indoor humidity, creating excessively dry air that severely irritates the respiratory tract and triggers asthma attacks.

Cevap

The advanced air-purification systems drastically reduce indoor humidity, creating excessively dry air that severely irritates the respiratory tract and triggers asthma attacks.
The correct answer resolves the paradox by introducing an unintended negative consequence of the air-purification systems. While the systems successfully perform their stated function of removing allergens, they simultaneously create excessively dry air. This dry air acts as a new, independent trigger for asthma attacks. This perfectly bridges the gap, explaining how the systems can be working exactly as intended regarding allergen removal while still ultimately causing an increase in the overall number of asthma attacks.

Adım Adım Çözüm

1

The air-purification systems eliminate 99 percent of indoor allergens and were installed in a majority of homes.
Understanding the expected positive outcome (fewer asthma attacks).
2
Identify the second premise (the conflict)
The total number of severe asthma attacks in the city actually increased over the same year.
Pinpointing the exact nature of the surprising outcome.
3
Evaluate options for a bridging mechanism
Locate an option that allows both premises to be true by introducing a new factor caused by the systems that triggers asthma independently of allergens.
A valid resolution must explain the increase in attacks without denying the reduction in allergens.

A regional hospital implemented a strict new triage protocol to reduce the burden on its emergency department. The protocol successfully redirects all patients with minor, non-critical injuries to an affiliated urgent care facility. A year after implementation, an internal audit confirmed that the emergency department had not treated a single non-critical patient. Nevertheless, the audit also revealed that the average cost of treatment per patient in the emergency department had risen by 35 percent compared to the year before the protocol was introduced.

Statement: The apparent discrepancy is successfully resolved if it is true that by removing the large volume of inexpensive, non-critical cases from the emergency department, the only cases remaining to be averaged were severe traumas and complex emergencies, which inherently require the most expensive medical interventions.

Cevabı ve açıklamayı göster

Cevap: True

Cevap

True. The statement successfully resolves the paradox by explaining how removing low-cost cases increases the average cost of the remaining patient pool.
The correct answer is True. The statement successfully bridges the conflicting premises by highlighting a shift in the composition of the patient population. The original average cost was a blend of many inexpensive treatments (minor injuries) and some expensive treatments (severe traumas). By effectively removing all the inexpensive treatments from the emergency department, the hospital ensured that the new average would be calculated exclusively from the highly expensive cases. This mathematical reality perfectly explains how the average cost per patient could rise by 35 percent even though the protocol worked exactly as intended.

Adım Adım Çözüm

1
Analyze the conflicting premises presented in the scenario.
The hospital successfully eliminated minor, low-cost injuries from the emergency department, yet the average cost per patient treated there increased by 35 percent.
Understanding the exact nature of the discrepancy is required before evaluating potential resolutions.
2
Evaluate the mechanism proposed in the statement.
The statement suggests that the increase in average cost is a direct mathematical result of removing inexpensive cases, leaving only the most expensive, severe traumas to be calculated in the new average.
We must determine if this new information logically allows both original premises to coexist without contradicting either one.
3
Apply logical and statistical reasoning to the proposed mechanism.
If the lowest values (inexpensive cases) are removed from a dataset, the average of the remaining values (expensive cases) will inevitably be higher than the original combined average.
This confirms that the proposed mechanism perfectly explains the surprising statistical outcome.

You can verify the logic by substituting hypothetical numbers: Assume 100 minor cases cost 100each,and10severecasescost100 each, and 10 severe cases cost 10,000 each. The original average is 110,000/110patients=110,000 / 110 patients = 1,000 per patient. If the protocol removes all 100 minor cases, the new average is 100,000/10patients=100,000 / 10 patients = 10,000 per patient. The average increased drastically simply by removing the low-cost cases.

To reduce its environmental footprint, a corporate office replaced all manual light switches with motion-sensor switches designed to turn lights off whenever a room is unoccupied. The building's occupancy rate, operating hours, and total number of light fixtures remained completely unchanged. Yet, one year after the installation, the building's total electricity consumption specifically for lighting had increased by 15% compared to the previous year.

Which of the following, if true, most helps to resolve the apparent paradox?

Cevabı ve açıklamayı göster

Cevap: The motion sensors automatically activate the lights at their maximum wattage upon detecting movement, whereas employees using the manual switches typically kept their office lights heavily dimmed.

Cevap

The statement that the motion sensors automatically activate the lights at their maximum wattage, whereas employees previously kept their lights heavily dimmed.
This option successfully resolves the discrepancy by introducing a new variable: light intensity (wattage). Even if the motion sensors reduce the total amount of time the lights are left on, automatically activating them at their maximum wattage uses significantly more electricity per minute than the heavily dimmed lights used previously. This higher rate of continuous consumption easily accounts for the 15% overall increase in electricity usage.

Adım Adım Çözüm

1
Analyze the apparent discrepancy presented in the stimulus.
The company installed motion sensors to turn off unoccupied lights, aiming to save energy. All other factors (occupancy, hours, fixtures) remained constant, yet lighting electricity consumption increased by 15%.
Understanding the exact parameters of the paradox is necessary to identify what kind of new information can bridge the gap.
2
Determine the requirements for a successful resolution.
The correct answer must provide a reason why the new sensors cause more electricity to be drawn when they are on, outweighing the energy saved when they turn lights off.
Since the time the lights are on has presumably decreased (or at least not increased), the rate of energy consumption while on must have increased to result in a net gain.
3
Evaluate the options against these requirements.
The option regarding maximum wattage provides the exact mechanism needed: higher intensity (wattage) uses more electricity than dimmed lights, fully explaining the absolute increase in consumption.
This is the only option that addresses the actual rate of electricity consumption rather than cost, outside correlations, or irrelevant percentages.

A national medical board recently released the annual pass rates for its certification exams. Overall, a significantly lower percentage of candidates who tested at urban centers passed their exams compared to candidates who tested at rural centers. However, when the board analyzed the data according to the candidates' specific medical specialties, they found that for every single medical specialty, the pass rate for candidates testing at urban centers was higher than the pass rate for candidates testing at rural centers.

Which one of the following, if true, most helps to resolve the apparent discrepancy described above?

Cevabı ve açıklamayı göster

Cevap: Urban testing centers disproportionately administer exams for medical specialties that have exceptionally low overall pass rates, whereas rural centers primarily administer exams for specialties with high overall pass rates.

Cevap

The statement indicating that urban centers disproportionately administer exams for exceptionally difficult specialties, while rural centers mostly administer exams for high-pass-rate specialties.
The correct answer resolves the paradox by introducing a phenomenon known in statistics as Simpson's Paradox. Even though urban candidates pass at a higher rate within each individual specialty, their overall average is dragged down because a disproportionately massive share of them are taking exams for exceptionally difficult specialties (which have inherently low pass rates for everyone). Meanwhile, rural candidates are mostly taking easier exams. Because the heavily weighted 'low pass rate' groups dominate the urban average, the overall urban pass rate drops below the rural average, cleanly resolving the discrepancy without contradicting the premises.

Adım Adım Çözüm

1
Identify the apparent contradiction in the stimulus.
Overall, the urban pass rate is lower than the rural pass rate. However, within every individual medical specialty, the urban pass rate is higher.
Accurately diagnosing the nature of the statistical discrepancy is required to find a logical resolution.
2
Determine the mathematical mechanism that can resolve a proportional paradox.
The resolution must explain how subgroup weighting affects overall averages. A group's overall rate is heavily influenced by the population sizes of its composite subgroups.
In statistics, an overall rate can be lower than a competitor's even if all its subgroup rates are higher, provided the group is heavily weighted toward subgroups with inherently lower baseline rates.
3
Evaluate the choices to find the statement that provides this statistical weighting.
The correct option reveals that urban centers have a much higher proportion of test-takers in difficult (low pass rate) specialties, artificially dragging down their overall average.
This mathematically bridges the two seemingly contradictory facts without violating either premise.

In an effort to restore the declining population of native silver trout in Lake Mistic, conservationists completely removed a non-native predatory fish species, the spotted pike, which was known to feed on juvenile silver trout. Two years after the complete removal of the spotted pike, the population of juvenile silver trout has actually declined significantly below its previous levels, despite water quality and other environmental factors remaining optimal and unchanged.

Which of the following, if true, most helps to resolve the apparent discrepancy?

Cevabı ve açıklamayı göster

Cevap: The spotted pike's primary food source was the redfin perch, a rapidly reproducing species whose diet consists almost entirely of the exact same aquatic insects that juvenile silver trout rely on for survival.

Cevap

The statement explaining that spotted pike primarily ate redfin perch, which compete directly with juvenile silver trout for food.
The correct answer resolves the paradox by introducing a secondary causal mechanism. By establishing that the spotted pike primarily preyed on redfin perch, and that redfin perch compete directly with juvenile silver trout for the exact same food source, it explains how removing the pike allowed the perch population to grow unchecked. The surging perch population then depleted the food supply, starving the juvenile trout.

Adım Adım Çözüm

In an effort to combat a rising rate of a severe tick-borne illness, the public health department of Woodlands County heavily subsidized a new, highly effective chemical tick repellent. The repellent was widely adopted and applied correctly by nearly all outdoor recreationists in the county. However, public health records indicate that in the year following the subsidy's introduction, the infection rate of the tick-borne illness among outdoor recreationists in Woodlands County increased significantly.

Which of the following, if true, most helps to resolve the apparent discrepancy?

Cevabı ve açıklamayı göster

Cevap: Confident in the new repellent's efficacy, outdoor recreationists in the county shifted from hiking exclusively on cleared paths to routinely navigating dense, untrailed brush where tick density is extraordinarily high.

Cevap

The statement indicating that recreationists, confident in the repellent, began navigating dense, untrailed brush where tick density is extraordinarily high.
The correct answer successfully resolves the paradox by demonstrating how the introduction of the protective measure directly caused a behavioral shift. Because the recreationists felt fully protected by the highly effective repellent, they began exposing themselves to overwhelmingly higher numbers of ticks in untrailed brush. This massive increase in exposure overwhelmed the preventative benefits of the repellent, perfectly explaining how a highly effective safety measure could ultimately result in a higher infection rate.

Adım Adım Çözüm

During a recent outbreak of the Z-virus, global health organizations compiled data for Region A and Region B, two regions with exactly the same total population size. The data revealed that the Z-virus mortality rate—defined strictly as the number of deaths per 100 confirmed infected individuals—was twice as high in Region A as it was in Region B. However, the total absolute number of people who died from the Z-virus was significantly lower in Region A than in Region B.

Cevap: The viral strain circulating in Region A was a highly lethal variant that burned out quickly due to extremely low transmissibility, whereas Region B was swept by a highly contagious but much milder variant.; Health authorities in Region A only recorded a confirmed Z-virus infection if a patient was hospitalized with severe respiratory failure, whereas Region B implemented mandatory proactive testing for all residents regardless of symptoms.

Cevap

The correct statements are the one detailing differing viral strains (lethal/low-spread vs. mild/high-spread) and the one detailing differing testing methodologies (severe-only testing vs. universal testing).
To resolve a statistical paradox where a rate is higher but an absolute count is lower, the denominator of that rate (in this case, the number of confirmed infected individuals) must be drastically smaller for the group with the higher rate. The two correct statements successfully provide real-world mechanisms for this massive denominator shift. The first does so biologically: a highly lethal but poorly transmitting virus yields a high death rate but few total cases. The second does so statistically: artificially shrinking the denominator by only testing the sickest patients inflates the apparent death rate, even if the absolute number of cases is small compared to a region that tests everyone.

Adım Adım Çözüm

1
Analyze the stimulus to isolate the two conflicting facts that form the paradox.
Fact 1: Mortality rate (Deaths / Infected) is much higher in Region A. Fact 2: Absolute total Deaths is much lower in Region A. Premise: Total populations are identical.
Identifying the mathematical relationship between the rate and the absolute count is required to evaluate the options.
2
Establish the logical requirements for a complete resolution.
A valid resolution must explain how Region A can have a high Deaths/Infected ratio while maintaining a low absolute number of Deaths, which mathematically requires Region A to have a drastically lower number of total Infected individuals compared to Region B.
Resolutions for rate-vs-count paradoxes invariably rely on massive shifts in the denominator (the baseline count).
3
Evaluate each option against the mathematical requirements established in Step 2.
The viral strain statement explains both the high rate in A (high lethality) and the low absolute deaths (low transmissibility). The testing methodology statement explains the high rate in A (denominator only includes severe cases) and allows for higher absolute deaths in B (widespread outbreak captured by universal testing).
Options must fully resolve the paradox without contradicting premises or deepening one side of the conflict.

To improve the durability of its flagship rugged smartphone, the Trekker, a telecommunications company analyzed thousands of broken units that customers had sent to the company's centralized repair facility over the past year. The engineers found that 85 percent of the damaged Trekkers had shattered outer screens, while only 5 percent had damaged internal processors. Based on this data, the engineering team proposed heavily reinforcing the screens on the next generation of the Trekker. However, the chief product architect rejected this proposal, arguing that if the goal is to maximize the average operational lifespan of the Trekker in the field, the company must instead prioritize reinforcing the internal processors.

Which of the following, if true, most helps to resolve the apparent discrepancy between the repair data and the architect's recommendation?

Cevabı ve açıklamayı göster

Cevap: When a Trekker's internal processor is damaged, the device typically becomes immediately inoperable and is discarded by the user, whereas units with shattered screens usually remain functional enough to justify the effort of returning them for repair.

Cevap

The statement explaining that devices with damaged processors are typically discarded, while those with shattered screens are returned for repair.
The correct answer provides a mechanism (survivorship bias) that perfectly reconciles the repair data with the architect's recommendation. If a damaged processor causes the user to instantly throw the phone away, those phones never make it to the repair facility to be counted. Conversely, a shattered screen leaves the phone functional enough to be mailed in. Therefore, the repair data vastly underestimates processor failures in the field. The architect realizes that to extend the phone's life, they must protect the component that causes total device death, not the one that merely results in a repair request.

Adım Adım Çözüm

1
Identify the apparent discrepancy or paradox in the stimulus.
Repair data shows screens break 85% of the time and processors only 5%. Yet, the architect insists that reinforcing processors is the key to maximizing the phone's lifespan.
Resolving a paradox requires clearly defining the two conflicting facts that need to be reconciled.
2
Analyze the nature of the evidence provided.
The data only comes from 'units that customers had sent to the company's centralized repair facility'.
In LSAT Logical Reasoning, the source and scope of data are critical. If data only represents a specific subset (returned phones), it may not accurately reflect the whole picture (all broken phones in the field).
3
Evaluate the options to find a factual statement that explains how both sides of the paradox can be true simultaneously.
The correct answer must explain why processor damage is actually a massive threat to the phone's lifespan despite barely showing up in the repair facility's data.
A valid resolution must bridge the gap without contradicting either of the established facts.
4
Select the option that introduces a selection bias into the data pool.
The correct option reveals that phones with broken processors are thrown away (thus never counted in the 5%), while those with broken screens survive long enough to be mailed in (inflating the 85%).
This perfectly explains why the repair data is skewed and why the architect is correct to focus on the fatal flaw (the processor) to extend actual field lifespan.

A new allergy medication, AllerClear, contains the exact same active compound as the leading brand, AllerSustain. However, AllerClear's unique formulation causes it to be metabolized and completely eliminated from the human body twice as rapidly as AllerSustain. Since the adverse side effects of this active compound are known to result from its presence in the bloodstream, researchers predicted that allergy sufferers would experience far fewer side effects with AllerClear. Yet, in a multi-month clinical trial where participants were instructed to take their assigned medication whenever their allergy symptoms flared up, those using AllerClear reported a significantly higher incidence of side effects than those using AllerSustain.

Which one of the following, if true, most helps to resolve the apparent discrepancy?

Cevabı ve açıklamayı göster

Cevap: Due to its rapid elimination, AllerClear provides only brief relief, causing participants to take the medication so frequently that their total cumulative exposure to the active compound far exceeds that of AllerSustain users.

Cevap

The statement explaining that rapid elimination leads to brief relief, which causes participants to take the medication more frequently and results in a higher total cumulative exposure.
The discrepancy arises because a medication designed to leave the body quickly (which was expected to reduce side effects) actually resulted in a higher incidence of side effects. The correct answer resolves this by introducing an unintended behavioral shift: because the drug leaves the body quickly, its therapeutic effects wear off rapidly. This prompts patients to take the medication much more frequently. Consequently, their total cumulative exposure to the active compound ends up being significantly higher than that of patients taking the slower-acting drug, perfectly explaining the higher incidence of side effects.

Adım Adım Çözüm

1
Identify the two conflicting facts presented in the stimulus.
Fact 1: AllerClear is eliminated twice as fast as AllerSustain, leading researchers to expect fewer side effects. Fact 2: Trial participants using AllerClear experienced a significantly higher rate of side effects.
Isolating the exact nature of the discrepancy is required before evaluating how to resolve it.
2
Determine the underlying assumption that makes the outcome surprising.
The researchers assumed that a faster elimination rate per dose would automatically result in less overall exposure to the active compound.
Identifying the gap in the researchers' reasoning helps predict the mechanism of a valid resolution.
3
Evaluate the options for a statement that bridges the gap without contradicting the premises.
The correct option reveals an unintended behavioral consequence: the fast elimination necessitates more frequent dosing. This frequency completely overrides the benefit of fast elimination, leading to higher total exposure.
A valid resolution must actively reconcile the two conflicting facts, showing how the expected cause (fast elimination) led to the unexpected outcome (more side effects).

The correct answer accurately encapsulates both contrasting facts presented in the stimulus: the fact that the algae population increased, and the fact that the lake's conditions were exactly the opposite of what algae typically need. It successfully isolates the point of tension without adding outside information or attempting to solve the mystery.

Adım Adım Çözüm

1
Analyze the stimulus to extract the factual premises.
Fact 1: The algae population increased massively. Fact 2: The lake had cold, moving water, but algae generally require warm, stagnant water to thrive.
Identifying a discrepancy requires breaking the stimulus down into its conflicting components.
2
Determine the precise point of logical tension.
The conflict is that an organism thrived in an environment that should have prevented its growth.
Understanding the exact nature of the contradiction helps in eliminating answers that miss the core issue.
3
Evaluate the options to find the one that simply states this conflict without attempting to explain or resolve it.
The correct option plainly contrasts the massive growth with the unfavorable conditions, matching the logical tension perfectly.

Last year, the city of Oakhaven implemented a strict water conservation program. In response, residents successfully reduced their average daily water usage by 20 percent per person. Surprisingly, despite this widespread compliance among residents, Oakhaven's total municipal water consumption was actually higher last year than it was the year before the program began.

Which one of the following, if true, most helps to resolve the apparent discrepancy in the information above?

Cevap: Several large manufacturing plants, which account for the majority of the city's overall water use, opened in Oakhaven last year.

Cevap

The correct answer is the option stating that several large manufacturing plants, which account for the majority of the city's overall water use, opened in Oakhaven last year.
The correct answer resolves the paradox by introducing a massive, non-residential source of water consumption. If industrial plants use the majority of the city's water and they just opened last year, this new industrial usage would easily outweigh the 20 percent reduction in residential usage. This perfectly explains how total municipal consumption increased while individual residential consumption decreased, allowing both premises to logically coexist.

Adım Adım Çözüm

1
Identify the two seemingly conflicting premises in the stimulus.
Premise 1: Residents reduced their per-person water usage by 20 percent. Premise 2: Total municipal water consumption increased.
Understanding the exact nature of the paradox is required before attempting to bridge the gap.
2
Determine what is missing or assumed between the conflicting facts.
The stimulus assumes that residential usage dictates total municipal usage, ignoring other potential categories of water consumers (like industrial, commercial, or agricultural users).
Identifying the 'missing link' allows you to anticipate the type of information needed to resolve the discrepancy.
3
Evaluate the options to find one that allows both premises to be true simultaneously.
The option regarding new manufacturing plants explains that a new, massive source of non-residential water consumption was introduced, which mathematically overrides the residential savings.
A correct resolution must explain the overall increase without contradicting the fact that individual residents successfully conserved water.

A municipality recently implemented a comprehensive ban on single-use plastic grocery bags with the stated goal of reducing the total volume of plastic waste generated by its residents. However, municipal data revealed that the city's total plastic waste actually increased significantly in the year following the implementation of the ban. The discovery that residents began purchasing thick, heavy-duty plastic trash liners—which use far more plastic per unit—to replace the free grocery bags they had previously reused for their household garbage effectively resolves this apparent discrepancy.

Cevabı ve açıklamayı göster

Cevap: True

Cevap

The statement is true.
The correct answer is True because a valid resolution to a paradox must introduce new information that allows both seemingly contradictory facts to coexist. In this case, the shift from reusing thin grocery bags to purchasing thick, heavy-duty trash bags perfectly explains how a ban on one plastic item logically led to an overall increase in total plastic waste.

Adım Adım Çözüm

1
Identify the apparent discrepancy in the scenario.
A ban on single-use plastic bags was followed by an unexpected increase in the city's total plastic waste.
Understanding the exact nature of the conflict is necessary to evaluate if the new information can resolve it.
2
Evaluate the new information provided as a potential resolution.
Residents started buying heavy-duty trash bags that contain far more plastic than the banned bags to use as garbage liners.
This determines the mechanism by which the new premise might bridge the gap.
3
Determine if the new information allows both original premises to logically coexist.
Yes. The ban eliminated thin bags but directly caused the purchase of thicker bags, resulting in a net increase in plastic waste.
A valid resolution to a paradox must fully explain how both conflicting facts can occur together in reality.

Last year, the city of Oakhaven banned the sale of sugary beverages in containers larger than 16 ounces, intending to reduce overall sugar consumption among its residents. However, a recent public health study reveals that in the year since the ban was implemented, the total volume of sugary beverages purchased and consumed by Oakhaven residents has increased significantly.

Which of the following, if true, most helps to resolve the apparent discrepancy described above?

Cevabı ve açıklamayı göster

Cevap: Consumers in Oakhaven typically respond to the new size restriction by purchasing two or more 16-ounce sugary beverages at a time, resulting in a higher total volume consumed per person.

Cevap

The statement explaining that consumers respond to the restriction by purchasing multiple 16-ounce beverages at a time.
The correct answer successfully resolves the paradox by introducing an unintended consequence of the policy. If consumers feel restricted by the 16-ounce limit and compensate by purchasing two or more drinks per transaction, their individual consumption (32 or more ounces) easily surpasses the previous single large container. This perfectly explains how a ban on large sizes can lead to a significant increase in total volume consumed, allowing both original facts to be true.

Adım Adım Çözüm

1
Identify the two apparently conflicting facts in the stimulus.
Fact 1: Oakhaven banned sugary drinks over 16 ounces to reduce consumption. Fact 2: The total volume of sugary drinks consumed has increased significantly since the ban.
Understanding the exact nature of the discrepancy is necessary to find a statement that bridges the gap.
2
Determine what is required to resolve the paradox.
The correct answer must explain how banning large sizes directly or indirectly caused residents to consume a higher total volume of sugary drinks.
A valid resolution must allow both facts to be true simultaneously without contradicting either.
3
Evaluate the answer choices against the required resolution.
The correct option provides an unintended behavioral shift (buying multiple smaller drinks) that directly explains how smaller individual sizes lead to greater total volume.
This is the only option that accounts for the increase in consumption while accepting the reality of the ban.

Cevap

The highway expansion paradox is resolved by the shift of commuters from trains to cars. The luxury perfume paradox is resolved by the loss of the product's exclusive image. The cheaper feed paradox is resolved by the need to consume significantly more feed.
Each correct match provides a piece of new information that actively bridges the gap between an action and its surprising result. For the highway, it introduces a behavioral shift. For the perfume, it introduces the concept of prestige pricing. For the farm, it introduces the relationship between nutritional density and required volume.

Adım Adım Çözüm

1
Analyze the highway paradox.
The paradox is that increasing road space worsened traffic. The matching resolution shows how more space led to even more cars.
Resolving a paradox requires finding a new fact that makes both original facts compatible.
2
Analyze the luxury perfume paradox.
The paradox is that lowering prices reduced sales. The matching resolution shows that the price cut removed the primary reason people bought the product.
We must explain why a normal economic principle failed in this specific scenario.
3
Analyze the farm feed paradox.
The paradox is that cheaper feed raised total costs. The matching resolution shows that the farm had to buy vastly more of the new feed.
Total cost depends on both price per unit and quantity used; changing one can offset the other.

In a particular forest ecosystem, the primary defense mechanism of the pale-winged Glider Moth against visually hunting predatory birds is its ability to blend in seamlessly with the light-colored bark of the region's dominant birch trees. Three years ago, a rapidly spreading fungal infection caused the bark of almost all these birch trees to turn completely black. Biologists predicted that this stark loss of camouflage would lead to a severe decline in the Glider Moth population due to increased predation. Yet, recent surveys show that the Glider Moth population is now more than double what it was before the fungal infection, even though the number of predatory birds in the forest has not decreased.

Which one of the following, if true, most helps to resolve the apparent discrepancy in the information above?

Cevabı ve açıklamayı göster

Cevap: The fungal infection completely eradicated a species of moss on the birch trunks that previously served as the exclusive breeding ground for a parasitic wasp, a pest that historically destroyed over eighty percent of all Glider Moth eggs.

Cevap

The statement explaining that the fungal infection eradicated a parasitic wasp that previously destroyed the vast majority of Glider Moth eggs.
The correct option perfectly resolves the discrepancy by introducing a powerful countervailing force. While the fungal infection harmed the moths by making adult moths visible to birds, it simultaneously eliminated a parasite that was destroying 80% of the moths' eggs. The massive increase in eggs surviving to adulthood more than compensates for the higher rate of adult predation, explaining how the overall population could more than double.

Adım Adım Çözüm

1
Identify the opposing premises in the stimulus.
Premise 1: Moths lost their camouflage against predators, so their population should plummet. Premise 2: Predator numbers didn't drop, yet the moth population actually doubled.
Understanding the exact nature of the paradox is required to find the bridging fact.
2
Formulate a structural requirement for the correct answer.
The correct answer must introduce a new, unstated effect of the fungal infection that severely benefits the moths, and this benefit must be powerful enough to completely overshadow the negative impact of being highly visible to predators.
A resolution must allow both premises to be true simultaneously without contradicting either.
3
Evaluate the options against the formulated requirement.
Only the option regarding the parasitic wasp provides a massive reproductive advantage (saving over 80% of eggs) caused by the same fungus that destroyed the camouflage.
This establishes a causal mechanism where the net effect of the fungus on the moth population is overwhelmingly positive, perfectly bridging the conflicting facts.

At the start of the fiscal year, a premium coffee brand transitioned to entirely eco-friendly, biodegradable packaging. Prior consumer surveys overwhelmingly indicated this move would increase customer loyalty and attract environmentally conscious buyers. However, six months after the transition, the brand's total sales volume had plummeted by 35%35\%, even though the retail price of the coffee remained unchanged and overall market demand for premium coffee grew.

Statement: The additional information that the new biodegradable packaging fails to seal out oxygen, causing the coffee beans to become noticeably stale within days of purchase, successfully resolves the apparent discrepancy.

Cevabı ve açıklamayı göster

Cevap: True

Cevap

True
The statement evaluates to true because the proposed additional fact perfectly bridges the two conflicting premises. The paradox is that a highly anticipated, eco-friendly change resulted in a massive loss of sales. The new information reveals a critical flaw in the new packaging (it ruins the coffee). This explains why consumers stopped buying the product despite liking the eco-friendly concept, successfully resolving the discrepancy.

Adım Adım Çözüm

1
Identify the apparent discrepancy in the stimulus.
Consumer surveys predicted the eco-friendly packaging would increase loyalty and attract buyers, but sales actually plummeted by 35%35\% in a growing market.
Understanding the exact nature of the paradox is required before attempting to resolve it.
2
Analyze the proposed bridging premise.
The new packaging fails to seal out oxygen, making the coffee noticeably stale very quickly.
We must determine the effect of this new information on the conflicting facts.
3
Evaluate if the new premise reconciles the conflict.
Yes. While the eco-friendly aspect is attractive, the rapid staling of the coffee destroys the product's fundamental value, completely explaining why actual sales dropped despite the positive environmental intentions.
A valid resolution must explain how both original premises can be logically true simultaneously.
