Below are four distinct causal claims along with their supporting evidence. Pair each claim with the abstract methodological finding that best resolves its primary logical gap.

  • An observational survey revealed that individuals who frequently consume Vitamin Z supplements experience significantly lower rates of joint inflammation. Researchers conclude that Vitamin Z actively suppresses inflammatory responses.Data reveals that the group exhibiting the beneficial outcome actually possessed baseline lifestyle traits that typically exacerbate the condition being studied.
  • Following a municipal ban on restaurant use of artificial trans fats, local cardiovascular emergencies dropped by 15 percent in a single year. Officials assert that the regulatory ban directly caused this rapid decline.Comparable populations that did not experience the regulatory intervention saw no similar reduction in adverse health outcomes over the identical timeframe.
  • Asthma patients who began using a newly designed ionic air purifier in their bedrooms reported a drastic reduction in symptoms after two months. The manufacturer asserts the device's novel filtration technology is responsible for the relief.Subjects utilizing a functionally inert but physically identical device reported no alleviation of their condition over an identical observation period.
  • Mice fed a diet exclusively consisting of a specific fermented grain lived 20 percent longer than mice fed a standard diet. Scientists hypothesize that the unique byproducts of the fermentation process are responsible for extending their lifespans.A control group exposed to the primary material in its original, unmodified state did not exhibit the beneficial outcome.

Cevap

The observational study (Vitamin Z) matches the finding about exacerbating baseline traits. The municipal ban matches the finding about comparable populations. The air purifier matches the finding about the inert device. The fermented grain matches the finding about the unmodified primary material.
Each correct match directly seals the unique logical vulnerability inherent in its corresponding causal argument. The observational study is strengthened by showing the correlation holds despite opposing confounders. The policy argument is strengthened by using neighboring regions as a control to rule out broader trends. The device argument is strengthened by ruling out the placebo effect via an inert replica. The biological experiment is strengthened by testing the base material to isolate the specific modification.

Adım Adım Çözüm

1
Analyze the observational study argument (Vitamin Z) to identify its causal gap.
The argument infers causation from correlation. A primary vulnerability is confounding variables (e.g., supplement users might generally have healthier lifestyles).
Identifying the specific flaw is required to find the statement that resolves it.
2
Identify the strengthening statement for the Vitamin Z argument.
The statement showing that the group possessed baseline traits that typically exacerbate the condition strengthens the argument.
This rules out positive confounding variables and highlights the efficacy of the vitamin, as it worked despite negative lifestyle factors.
3
Analyze the municipal ban argument to identify its causal gap.
The argument assumes a sequential relationship (ban, then drop in emergencies) is causal. It is vulnerable to concurrent historical trends (e.g., general medical advancements).
Understanding 'post hoc ergo propter hoc' vulnerabilities is key to policy analysis.
4
Identify the strengthening statement for the municipal ban argument.
The statement showing comparable populations without the intervention did not see the reduction addresses this gap.
It acts as a natural control group, ruling out broader concurrent trends as the cause.
5
Analyze the air purifier argument to identify its causal gap.
The argument relies on self-reported symptom reduction after using a new device, which is highly susceptible to the placebo effect.
Any visible intervention can cause perceived psychological and physiological relief.
6
Identify the strengthening statement for the air purifier argument.
The statement regarding an inert but physically identical device addresses this gap.
It effectively creates a blind control group, isolating the device's actual technology from the placebo effect.
7
Analyze the fermented grain argument to identify its causal gap.
The scientists attribute the benefit specifically to the fermentation process, ignoring the possibility that the base grain itself is the cause.
When a modified material has an effect, one must isolate the modification from the base material.
8
Identify the strengthening statement for the fermented grain argument.
The statement showing that the unmodified primary material did not produce the outcome effectively seals this gap.
It isolates the fermentation process as the true causal variable.
