Question 41Question →

In the study of art history, researchers long believed that the vibrant blue pigment used in ancient Maya murals, known as Maya Blue, was highly susceptible to biodegradation over centuries due to its organic dye component, indigo. ________, recent chemical analysis has revealed that the encapsulation of indigo molecules within the crystalline channels of the clay palygorskite creates a highly stable organo-clay complex that is impervious to acids, alkalis, and microbial attack.

Which choice completes the passage with the most logical transition?

Show answer & explanation

Answer: However,

Answer

However,
The correct answer is the option stating 'However,'. The first sentence outlines a long-held belief that Maya Blue pigment is vulnerable to biodegradation. The second sentence presents recent chemical findings showing that it is actually highly stable and resistant to damage. This transition of ideas is a direct contrast, which is correctly signaled by 'However,'.

Step-by-Step Solution

1
Analyze the relationship between the two parts of the passage.
The first sentence notes a historical belief that Maya Blue pigment is fragile and susceptible to biodegradation. The second sentence introduces modern scientific evidence showing that the pigment is extremely stable and resistant to decay.
Understanding the logical connection between the ideas is necessary to determine the correct transition.
2
Determine the type of transition required.
Since the passage moves from a belief of susceptibility to a finding of high durability, a contrast or concession transition is needed to connect these opposing ideas.
This establishes the logical relation that the correct transition must signal.
3
Evaluate the choices based on the identified relationship.
The option stating 'However,' is a contrast transition and fits the context. The option stating 'Subsequently,' signals chronology; the option stating 'For instance,' signals exemplification; and the option stating 'Furthermore,' signals addition. None of these other options express contrast.
Only one option correctly aligns with the contrast relationship established in the passage.

Many cognitive scientists hypothesized that language acquisition in infants relies entirely on domain-general learning mechanisms, such as pattern recognition and statistical learning. A recent study by Dr. Clara Mendez showed that infants are highly sensitive to statistical regularities in speech. ________, Mendez's team observed that this sensitivity alone is insufficient for infants to grasp syntactic structure, which appears to require innate domain-specific constraints.

Which choice completes the passage with the most logical transition?

Show answer & explanation

Answer: Nevertheless

Answer

The transition 'Nevertheless' is the most logical choice because it establishes a contrast or concession, indicating that despite the evidence of infants' statistical sensitivity, this sensitivity remains insufficient for acquiring syntax.
The transition 'Nevertheless' is correct because it properly establishes a contrast/concession relationship. The preceding sentence highlights a positive finding (infants' high sensitivity to statistical regularities), while the subsequent sentence introduces a critical limitation (this sensitivity is insufficient on its own for syntax acquisition). 'Nevertheless' correctly signals this concession.

Step-by-Step Solution

1
Identify the relationship between the ideas in the sentences surrounding the blank.
The sentence before the blank describes a finding that infants are highly sensitive to statistical patterns. The sentence after the blank points out that this sensitivity is not enough for infants to acquire grammar.
Understanding the logical connection between the statements is necessary to choose the correct transition.
2
Determine the type of transition required to connect these ideas.
A transition indicating contrast or concession is needed because the second statement introduces a limitation that qualifies the positive finding of the first statement.
This guides the selection of the transition word that matches the logical direction of the text.
3
Evaluate the choices to find the one that fits the contrast/concession relationship.
'Nevertheless' is the only transition among the choices that expresses contrast or concession.
Selecting the correct transition ensures the passage flows logically and coherent meaning is maintained.

Question 43Question →

For decades, paleontologists debated whether dinosaurs were endothermic (warm-blooded) or ectothermic (cold-blooded), with many assuming that their massive size would make active metabolic heating unsustainable. Recent isotopic analysis of fossilized eggshells, which provides a direct record of female body temperatures during ovulation, has revealed internal temperatures comparable to those of modern birds. __________, some researchers argue that these high temperatures might simply reflect passive heat retention from warm environments rather than true endothermy.

Which choice completes the text with the most logical transition?

Show answer & explanation

Answer: Still

Answer

Still
The correct answer is the word that establishes a concession or contrast relationship between the two findings. The passage notes that recent eggshell analysis shows body temperatures similar to modern birds, which would suggest warm-bloodedness. However, the next sentence introduces a counter-interpretation: that these high temperatures might be due to environmental heat retention. The transition 'Still' correctly signals that this alternative interpretation exists and must be considered despite the new physical evidence.

Step-by-Step Solution

1
Analyze the relationship between the ideas in the passage.
The second sentence presents evidence supporting dinosaur endothermy (high eggshell-derived temperatures comparable to modern birds). The third sentence introduces a counter-argument or alternative interpretation (the temperatures could be due to environmental heat retention rather than metabolic regulation).
Identifying the relationship between sentences is necessary to choose the correct transition.
2
Determine the type of transition needed.
A transition indicating contrast or concession is needed because the final sentence presents a point that qualifies or runs counter to the implication of the preceding sentence.
This narrows down the choices to contrast/concession transitions.
3
Evaluate the choices against the required transition type.
The transition 'Still' functions as a contrast/concession transition, indicating that the alternative explanation exists despite the evidence of high temperatures. The other choices represent addition, elaboration, and chronological sequence, respectively.
Selecting the option that correctly represents the contrast relationship yields the correct answer.

Question 44Question →

While many plant species rely on vibrant flower colors to attract specific insect pollinators, the wild ginger (*Asarum canadense*) produces inconspicuous, brown blossoms that grow close to the ground, hidden beneath leaf litter. Early botanists hypothesized that these dull flowers were self-pollinating or relied entirely on crawling insects like ants. __________, recent video-tracking studies show that fungus gnats, flying insects attracted by the flower's fungus-like odor, are the primary pollinators of the plant.

Which choice completes the text with the most logical transition?

Show answer & explanation

Answer: However,

Answer

The correct transition is 'However', which signals a contrast between the early hypothesis and the recent research findings.
The transition 'However' is correct because it establishes a contrast between the early botanical hypothesis (that wild ginger is pollinated by crawling insects or self-pollinates) and the recent scientific finding that flying fungus gnats are its primary pollinators.

Step-by-Step Solution

1
Analyze the relationship between the ideas in the passage.
The first two sentences describe an early hypothesis that wild ginger relies on self-pollination or crawling insects. The third sentence presents empirical evidence that flying fungus gnats are the primary pollinators.
Identifying the relationship between the sentences is necessary to determine the logical transition needed.
2
Determine the logical connection required.
The finding that flying insects pollinate the plant directly contradicts the hypothesis that it relies on crawling insects or self-pollination. Therefore, a transition signaling contrast or concession is required.
Choosing the logical relation guides the selection of the correct transition category.
3
Evaluate the choices to find the contrast transition.
'However' is the only option that signals contrast, whereas 'Furthermore' indicates addition, 'Consequently' indicates cause-and-effect, and 'Specifically' indicates elaboration.
Matching the required logical relation to the transition definitions identifies the correct answer.

Question 45Question →

In behavioral economics, the endowment effect describes the tendency of individuals to value an item more highly simply because they own it. Early researchers hypothesized that this cognitive bias was a universal human trait shaped by evolutionary adaptation. ________, subsequent cross-cultural studies conducted by anthropologists have revealed that the effect is significantly less pronounced, and in some cases entirely absent, among populations in non-industrialized societies that practice communal ownership.

Which choice completes the text with the most logical transition?

Show answer & explanation

Answer: However

Answer

The transition 'However' is the correct choice because it signals a contrast between the early hypothesis that the endowment effect is a universal trait and subsequent cross-cultural evidence showing it is not.
The passage presents a contrast between the assumption that the endowment effect is a universal human trait and the subsequent cross-cultural evidence showing that the effect is absent or weakened in societies with communal ownership. The transition 'However' correctly establishes this relationship of contrast.

Step-by-Step Solution

1
Analyze the relationship between the two main ideas in the passage.
The first idea is that early researchers believed the endowment effect was a universal trait. The second idea is that subsequent cross-cultural studies found the effect is absent or weaker in communal societies.
Identifying the relationship between these sentences is necessary to select the correct transition.
2
Determine the logical connection between these two ideas.
The second idea contradicts or qualifies the first idea, establishing a relationship of contrast or concession.
The correct transition word must signal this contrast.
3
Evaluate the transition options to find the one that signals contrast.
'However' is a contrast transition, whereas 'Furthermore' signals addition, 'Consequently' signals cause-and-effect, and 'Specifically' signals elaboration.
Matching the identified logical relationship with the correct category of transition word leads to the right answer.
