Women receive fewer speeding tickets than men do. Women also have lower car insurance rates. It is clear that women are better drivers than men. The preceding conclusion is based on which of the following assumptions?

I. Men and women drive cars equal distances and with equal frequency.

II. Having lower car insurance rates indicates that one is a better driver than those who have higher rates.

III. Speeding tickets are equally awarded for violations without any gender bias on the part of police officers.

(A) I only

(B) III only

(C) I and III only

(D) II and III only

(E) I, II, and III

OFFICIAL EXPLANATION:

As always, read the question first. Because it references assumptions, we bet you figured out pretty quickly that it’s a seeking-assumptions question.

Next, read through the argument and try to figure out the assumption or assumptions the author makes in reaching the conclusion that women are better drivers. The author moves from the premises to the conclusion pretty quickly and assumes that fewer speeding tickets and lower car insurance rates indicate better driving skills. The author also assumes that men and women have equal driving experiences. Use this information to examine each of your options.

Look at Statement I first. It fits with your second observation that men and women experience equal driving situations, so eliminate any answer choices that don’t include Statement I. This means that you can get rid of Choices (B) and (D), which leaves you with Choices (A), (C), and (E).

Before you continue reading through your options, examine the remaining answer choices. You’ll see that it’s best to examine Statement II next, because if it’s true, you won’t even have to read Statement III; you’ll know the answer is Choice (E). You have to read Statement III only if you determine that Statement II isn’t an assumption. (For more about strategies for answering Roman numeral questions, see Chapter 2.)

The information in Statement II links the author’s last premise, that women have lower insurance rates, to the conclusion that women are better drivers. Thus, Statement II is also correct. You can eliminate Choices (A) and (C), and by process of elimination, the answer must be Choice (E). If you read through Statement III, you’ll confirm that it, too, is an assumption the author makes about men and women having an equal playing field in the driving game.

If you find seeking-assumption questions to be tricky, try arguing the opposite position. For example, in the sample question, you could’ve taken the opposing view, that men are better drivers. This means you’ll be looking for ways to undermine the conclusion. If you assume the premises to be true, the best way to attack the conclusion is to show that the author assumes things that aren’t true. For example, you may argue that men have more accidents because they drive more, they get more tickets because police are less forgiving with male speeders, and they have higher car insurance rates because they drive more-expensive cars. Those counterarguments expose the author’s assumptions!
