Hello @molinde,

For this type of question, we need to take a set of rules given by the passage, and apply them to the specific scenarios given by the answer choices. The principle will be most applicable to one of these choices, and that will be our correct answer.

If one does not have enough information (not EI), one should not make a decision (not MD.)
not EI - - - - - - > not MD

Rather, one should seek information (SI) until a well-informed decision can be made.
not EI - - - - - - - > SI

I'll explain why D is the right answer. A key word here is "inadequate." It tells us that personal experience with cars is not enough information. Therefore, according to our principle, what shouldn't we do? We should not make a decision. D matches this by saying one should not choose a car.

According to our principle, what should we do when we don't have enough information? We should seek more information until we have enough. D conforms to this by recommending that we study these cars further. Do you see how D acts in accordance with our rules?

Let's look at some wrong answers. For example, C may seem appealing because it references a search for further information. However, this option does not have a decision to be made, so our principle does not apply.

E is another good example. The first half is correct. It fits our not EI - - - -> not MD formula. However, it is missing the second part of our formula. There is no effort to seek information, so it does not conform to our principles.

Why is B not the answer?

B does not work because its' saying to pay attention to all of the information you have. However, there isn't anything about not having enough information; rather, it's simply saying to carefully use the adequate information that you do have. Thus, we can get rid of this choice.
