TO STRENGTHEN ARGUMENTS, STRENGTHEN THE SUPPORT RELATIONSHIP.
For LSAT Strengthen Questions, you want to strengthen the support relationship between the premises and the conclusion. That means you make the beam thicker. (Remember Goku's Kamehameha from the lesson on Weakening Arguments?) You can do that by either adding additional premises – the analogy there would be to appeal to Goku’s friends to also fire up some beams. Or you can add information that makes the existing premises more relevant to the conclusion – the analogy there would be to feed Goku some magical beans that make him stronger.
LSAT Weaken questions and LSAT Strengthening questions are exactly the same. For any Weakening question on the LSAT, you can turn it into a strengthening question by changing around a few words and vice versa. It’s all about the assumptions. Whereas for Weaken questions, your task is to expose and deny any assumptions made, thereby weakening the support structure between the premises and the conclusion, here, in Strengthen questions, your task is to expose and affirm any assumptions made, thereby strengthening the support structure between the premises and the conclusion. The two question types are entirely interchangeable.
SOME SAMPLE STRENGTHEN QUESTION STEMS
- Which one of the following, if true, most strengthens the argument?
- Which one of the following, if true, would most strengthen the archaeologist’s reasoning?
- Which one of the following, if true, lends the most support to the psychologist’s conclusion?
- Which one of the following, if true, most strengthens the economist’s reasoning?
That relationship is the support relationship. That means you are to make the premises more supportive of the conclusion.
