Evaluate Argument

Hey Soumita,

For evaluate-the-argument style questions, you need to study the conclusion and premise, as with any other assumption style question.

Conclusion: The proportion of women AMONG people adhering to a low-carb diet has gone up.

Premise: The percent of women adhering to a low-carb diet has gone up.

Now, BEFORE YOU LOOK AT THE ANSWER CHOICES, you need to figure out what's missing from this argument. There's a reason why they're asking you what information would help you; as it stands, a piece of information is missing.

In this example, they go from a statistic about ONLY women to a statistic about ALL people. What we're missing here is men. If the proportion of both women has gone up AND the proportion of men has gone down, then the conclusion would definitely be true. But if all we know is that the percent of women has gone up, it could be that the percent of men has gone up MORE, so the proportion of women among people adhering to a diet has actually gone down.

So, the answer to your general question is: study the conclusion and premise and locate the missing piece of information yourself. Then you'll be armed when you go into the answer choices.
