Question 10

Two questions are based on one passage. Don't skip these questions because you need analyze only one passage or argument.

Notice that this passage is not an argument. Hence, you should not automatically look for a conclusion. It is a bland statement that simply reports a decline in the use of illegal drugs by high school seniors. NOTE THAT THE SCOPE OF THE STATEMENT IS ABOUT HIGH SCHOOL SENIORS!

The first question asks what casts doubt on the relevance of the study about high school seniors for drawing conclusions about the teen-age population as a whole.

Compare And Contrast The Answer Choices:

(A) Who cares. We are asked about the relevance of this study. Reject.

(B) This has nothing to do with applying a study about high school seniors to the teen-age population as a whole. Reject.

(C) This is a strong answer. It means that the sample group (high school seniors) is not representative of the teen-age population as a whole. If the sample is not representative of a certain group, it would be a mistake to apply the results of a study to that group.

But, don't select it yet. In critical thinking you should never select an answer until you have read every word of every choice.

(D) This is irrelevant on its face. Reject.

(E) This is irrelevant to applying a study of high school seniors to the teen-age population as a whole.

(C) is the best of the answer choices.
