Preptest 10 Section 1 Question # 24

The diagram of the correct answer choice makes it seem to mean something completely different than it's actually supposed to mean. It contains an "if" that creates a causal relationship that they clearly do not intend. Do they still pull tricks like that?

Preptest 9, Section 2, Question #25

This is a necessary assumption question, I think. The question stem is: "The argument assumes that." Using the negation method, answer choice B (as opposed to A, which is correct) really seems like the best choice.

The stimulus talks about how medical research is usually made public only after undergoing peer review and being published in a medical journal. It concludes that even though it takes time, it's necessary because the public might otherwise make decisions based on bad research.

The correct answer reiterates that peer research is necessary but can occur without publication in a journal. The one I like says that people apart from the review panel won't be able to adequately evaluate the argument.

Preptest 9, Section 2, Question #23

This is straightforward logic, but I am finding it really difficult. The question consists of two or statements:

You are a or b, and you are x or y. If you are b, you are x. So all a are y.

How is this diagrammed? The question asks what must be assumed to come to the conclusion.

The answer is x-->b.

Preptest 7, Section 4, Question #:12

This question asks us to choose which statement is undermined by the stimulus. To summarize, it says that corporate clients are using an ad. campaign that gives politicians free air time. The correct answer choice says that an ad. campaign is useful only if is persuades the audience.

I do not see how the language in the stimulus contradicts the answer choice in any way. The stimulus does not say that the advertising campaign ONLY provides free publicity and air time. How do we know that a company can't use it to persuade the audience?

This might be a loosely written question, but I want to make sure my reasoning isn't wrong.
