In one of the earliest Data Sufficiency posts on this blog, which you can read here and here, we discussed how the GMAT test-makers use the C-Trap to lure test-takers into making a mistake. The beauty of such questions is that the test-takers d not even realise that they have made a mistake. On the contrary they are very confident that they have answered it correctly. The C-Trap is set to lull test-takers into thinking that they can easily get the answer by using both the statements. But while both statements together will give you the answer, the question you need to ask is whether both statements are in fact required. Remember you need to choose option (C) only if both statements ARE required.
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.
