In the two previous posts we discussed two of the three argument types around which Strengthen-Weaken question of GMAT Critical Reasoning are posed — Plan of Action and X causes Y .The third type is also X causes Y but an argument built on Correlation-Causation and hence it is better to classify it as the Correlation-Causation type.

In the previous post on the Strengthen-Weaken question type, we discussed that there were three argument types around which strengthen-weaken type of questions are posed Plan of Action (PoA) X causes Y Correlation-Causation We discussed the PoA type of argument in that post, in this one we will look at the second type – X causes Y.
We have covered almost all the Critical Reasoning question types on the blog. A few readers had asked for specific posts on the Strengthen/Weaken Type, so the next few posts will cover these two question types in detail. Strengthen/Weaken question types together constitute the maximum number of questions out of the 13-15 Critical Reasoning questions you will encounter on the Verbal section of the GMAT. Strengthen/Weaken questions are usually broadly based on three types of argument structures: Plan of Action X causes Y Correlation-Causation We will take up one argument structure at a time and discuss the process to solve each type.

So answer options that give explanations that do not have a statistical implication can easily be ruled out. Let us look at the question below.
The biggest misconception about Critical Reasoning questions on the GMAT® is that they are based on common sense. Well, nothing could be farther from the truth. In fact, CR questions are based on rules of formal logic. The question from the Official Guide (OG) below is a perfect illustration. A study of marital relationships in which one partner’s sleeping and waking cycles differ from those of the other partner reveals that such couples share fewer activities with each other and have more violent arguments than do couples in a relationship in which both partners follow the same sleeping and waking patterns.
