E) 200

Question #2: Which of the following CANNOT be the greatest common divisor of positive integers x and y?

A) 1

B) 2x – y

C) y

D) x

E) x + 2y

Notice that we don’t need the answer choices to solve question #1, but we need them to solve question #2. Question #2 falls into a category of questions we’ll call “Analyze the Answer Choices” questions, because they require us to analyze each answer choice.  Questions of this nature typically ask Which of the following COULD be…? orWhich of the following CANNOT be…? but there are other variations as well.

The ONLY advice I’m offering in this brief article

When you encounter an “Analyze the Answer Choices” question, always check the answer choices from E to A, because the correct answer is typically closer to the bottom than to the top.

Now, I should mention that I’ve offered this advice for many years, but I’ve never actually backed it up with hard evidence beyond casual observations of questions in this category. For this article, I decided to find that hard evidence. So, I checked all of the Problem Solving questions in three Official Guides for GMAT Review (the 8thedition, 11th edition and 13th edition). Within those three resources, I found 28 different “Analyze the Answer Choices” questions. The frequencies were as follows:
