Quick overview of GMAT Verbal Critical Reasoning Section.
Strategy
- Preview the question stem.
- Read the stimulus critically looking for conclusion and premise/evidence and paraphrasing. Keep question stem in mind.
- Paraphrase the answer (or have general idea).
- Approach the answer choices looking for expected answer. If you can’t find, eliminate until you are left with correct choice.
Question type
- Assumption
- Strengthen or weaken – will generally attack/support assumption or evidence.
- Inference question – must be true if argument is true
- Structure (Method of Reasoning/Flaw in the reasoning) -
- Resolve/explain the discrepancy – similar to assumption but no conclusion presented. Answer supports two contradicting facts presented.
- Evaluate the argument – similar to strengthen/weaken
- Parallel reasoning – Reduce the passage to basic level leaving specifics (If X, then Y)and then make a best guess.
- Main Point – Paraphrased Conclusion
First three are more common.
Types of arguments
- Causal – x and y are correlated, so x must cause y. Assumption is generally that there is true causal relationship, there are no other causes and that x causes y (and not y causes x).
- Sampling – small sample extrapolated to larger group. Assumption is generally that sample is representative.
- Analogy – comparison between two things to reach an argument. Assumption is that two things are similar enough for the analogy to be realistic.
- Formula – uses average, mean ratio, percentage etc to draw conclusion. Assumption is that the formula used can be applied to the population.
CR Tips
- Understand the concept of Premise, Additional Premise, Counter premise, Assumption and Conclusion in arguments. These could be with or without Premise indicators (because, since, for example etc) , Additional Premise indicators (Furthermore, Moreover, Beside etc), Counter premise indicators (But, Yet, However, Although etc) Conclusion indicators (thus, therefore, hence, so etc).
- Some of the CR passages are Facts (no conclusion). Only question type possible on these passages are resolve the paradox or inference question because of unavailability of conclusion.
- Be look out for Quantity words (Most, Some, Few, Several etc) and Probability indicators (Never, will, could, would, likely, rarely etc). Wrong answer choices will sometime contain narrower or wider scope.
- Fill in questions are Assumption question (ends with Premise indicators Because, Since etc) OR Main Idea question (ends with Conclusion indicators Thus, Therefore etc) OR Inference question.
