Is the conclusion not too vague? ­Researchers recently studied the relationship between diet and mood, using a diverse sample of 1,000 adults. It was found that those who ate the most chocolate were the most likely to feel depressed. Therefore, by reducing excessive chocolate consumption, adults can almost certainly improve their mood.

- "Most chocolate... depressed"
- "Therefore EXCESSIVE choc... improve mood"

Is most chocolate = excessive amount of chocolate? It is vague IMO.

Answer: C. It draws a conclusion about a causal relationship between two phenomena from evidence that merely suggests that there is a correlation between those phenomena.

Explanation:

Understanding the Argument:
• Premise: A study of 1,000 adults found that those who ate the most chocolate were the most likely to feel depressed.
• Conclusion: Reducing excessive chocolate consumption will almost certainly improve adults’ mood.

The argument assumes a causal relationship between eating chocolate and depression. However, the study provides evidence only of a correlation between chocolate consumption and depression, not causation.

Analyzing the Answer Choices:

• (A): It improperly infers from the fact that a substance causally contributes to a condition that a reduction in the consumption of the substance is likely to eliminate that condition.
• The argument does not establish a causal link between chocolate consumption and depression in the first place. Instead, it assumes causation from correlation, which makes this option incorrect.
• (B): It draws a conclusion about the population as a whole on the basis of a sample that is unlikely to be representative of that population.
• There is no evidence in the passage to suggest that the sample is unrepresentative. The argument relies on a potentially flawed assumption about causation, not the representativeness of the sample.
• (C): It draws a conclusion about a causal relationship between two phenomena from evidence that merely suggests that there is a correlation between those phenomena.
• Correct. This accurately describes the flaw. The argument assumes that eating chocolate causes depression, but the evidence only suggests a correlation, not causation. Other explanations for the correlation, such as depressed individuals eating more chocolate, are ignored.
• (D): It confuses a condition that is necessary for establishing the truth of the conclusion with a condition that is sufficient for establishing the truth of the conclusion.
• This describes a different type of reasoning flaw. The argument does not depend on a necessary/sufficient condition confusion.
• (E): Its conclusion is worded too vaguely to evaluate the degree to which the premises support the truth of the conclusion.
• The conclusion is not vague; it clearly states that reducing chocolate consumption will “almost certainly” improve mood. The issue lies in the assumption of causation, not in the vagueness of the conclusion.

Conclusion:

The argument’s main flaw is assuming a causal relationship between chocolate consumption and depression based on evidence of correlation. Therefore, option C is the correct answer.

I am confused about A here.

I do believe that the author improperly infers the causal link between the two and then suggest reduction in chocolate could lead to elimination of the condition.

I do feel the latter part is a little awkwardly worded, but is that the option choice that would help us eliminate this OC completely?

Be careful about rewording the answer choices! (A) doesn't say that the author improperly infers a causal link. Take another look:

Quote:
It improperly infers from the fact that a substance causally contributes to a condition that a reduction in the consumption of the substance is likely to eliminate that condition.
In essence, (A) states that the author made an improper leap from (1) the fact that a substance causes a condition to (2) a reduction in that substance eliminates the condition.

An example of such reasoning might be something like this: "because eating too much fast food can cause obesity, cutting out fast food would completely eliminate obesity." A logical flaw to be sure. But not the flaw in the question.

The real flaw is that the author assumes a causal relationship based on a correlation. Not that the author assumes we can completely cure a problem by eliminating the cause.

I hope that clears things up!
