 Making connections task

Inference problems occur in many parts of the GMAT, not just in Critical Reasoning problems.

1.      Find some examples of quant and verbal inference problems (you’ll need to think about what exactly makes an inference problem in order to do this).

2.      What words and phrases show that a problem is an inference problem?

3.      The strategy of eliminating incorrect examples by showing that they could be false also works on quant problems. How would you go about using this strategy for quant problems?

(Answers below)

Making connections task answers

1.     Inference problems can be found in Reading Comprehension and in Problem Solving.

2.   RC inference problems often contain the wording ‘The passage suggests…’ and ‘It can be inferred that…’ PS inference problems often contain the wording ‘which of the following must be true?’

3.   Quant inference problems can usually be solved by testing cases, i.e. picking examples of numbers that agree with the information given, but contradict some of the answer choices, thus showing that the answer choice is not a correct inference.
