# What do Strengthen Questions look like?

Strengthen questions ask you to identify possible gaps between the evidence presented in a stimulus and the conclusion drawn, and then narrow those gaps by adding new evidence. The answer choice will present a fact that makes it more likely for the conclusion to be accurate. However, it does not have to make it absolutely certain that the conclusion is correct. If I said that cats are lazier than dogs because cats sleep 18 hours a day, you could strengthen my argument by saying that dogs sleep only 12 hours a day. That still doesn’t prove that cats are lazier, but it supports the theory that they are.

Below is a list of some of the common ways in which a Strengthen question can be phrased. If you’ve seen one that isn’t on this list, please leave it in a comment so we can include it.

• Which of the following, if true, most strengthens the argument?
• Which of the following, if true, adds the most support to the conclusion?
• The conclusion is most strongly supported if which of the following is true?
• Which of the following, if true, argues most strongly for [the conclusion]?
• Each of the following, if true, supports the argument EXCEPT…
• Which of the following would account for the evidence without supporting the conclusion?

Most Strengthen questions will have some form of the phrase “if true” in the prompt. The last example includes this phrase, but also provides an excellent illustration of how well-disguised some Strengthen questions are. In this case, it’s a Strengthen EXCEPT question because four answer choices will support the conclusion and one will not (but won’t necessarily weaken it either).With Strengthen questions, the trick is to identify that the question is asking you to provide a piece of information that is not explicitly stated, but that helps to narrow any gaps between the evidence and the conclusion.
