Multiple-Part Answer Choices
Multiple-choice questions may have answer choices that include two or more parts. In such cases, each part of the answer must be true for the entire answer choice to be correct. Even if you are uncertain of the correct answer, you can still improve your chances by eliminating any answer choices that you know are incorrect. For example, consider the following question:
Which of the following accurately describes how ocean conditions change with greater depth?
pressure decreases
density increases
temperature decreases
I only
III only
I and II
II and III
I, II, and III
If you know that pressure increases with greater depth, you know that I is wrong. Therefore, you can eliminate choices A, C, and E, since each includes I as part of the answer. If you know that II is correct, you can also eliminate choice B.
