  1. Gmat critical reasoning Spring 2014

  2. Getting started • 1. Read the question • 2. Identify the type of question • 3. Read the stimulus (paragraph) • 4. Identify conclusion (C) and evidence (E).

  3. Break down the argument • Conclusion = Main Idea • Must be true • Evidence = supporting details

  4. Conclusion key words • Therefore Thus As a result Hence Clearly So Consequently • Evidence key words: because since for

  5. Assumption • MUST BE TRUE for the Conclusion to be true.

  6. Andaman Islands problem • Conclusion: Travel co. with tours to islands risk-free way to make $$. • Assumption: All the people who WANT to go WILL go or CAN go.

  7. Chimps’ lifespan problem • Conclusion: Steady chromium intake lowers life expectancy of chimps in captivity • Evidence: contrast btwn lifespan of chimps in wild and chimps in captivity • Assumption: Chimps in captivity and chimps in the wild have the same lifespan.

  8. Types of questions • Assumption question: The assumption IS the answer. • You can often predict the answer • Remember: the assumption MUST be true in order for the conclusion to be true.

  9. Sample assumption questions • ASSUMED • ASSUMPTION • MAKE THE CONCLUSION LOGICAL (MEANS CONCLUSION IS TRUE • VALIDITY OF THE ARGUMENT DEPENDS ON • ARGUMENT PRESUPPOSES WHICH ONE

  10. STRENGTHEN/WEAKEN QUESTIONS • ATTACK THE CONCLUSION • ANSWER IS AN ADDITIONAL PIECE OF EVIDENCE • WEAKEN QUESTIONS MAKE THE ASSUMPTION NOT TRUE • STRENGTHEN QUESTIONS MAKE THE ASSUMTION TRUE

  11. Key words for strengthen/weaken questions • Weaken questions: most weaken, seriously damage, casts the most doubt, seriously call into question • Strengthen questions: most strengthen, provide the most support for, argument would be more persuasive if…

  12. Inference questions • Answer is the Conclusion • Inferable • Implied by • If all the statements, which of the following must also be true • The statements above, if true, support which of the following. • Which of the following is best supported by the statements above? • The statements above best support which of the following conclusions?

  13. Most common question types • Assumption • Strengthen • Weaken • Inference

  14. Explain question • Look at the LOGIC. • How could two facts actually be true, even though they SEEM to contradict each other? • Which of the following would best explain the discrepancy above? • Which of the following would best resolve the paradox described above

  15. Flaw question • What is already WRONG with the argument? • Which of the following is a flaw in the reasoning above? • The argument above is vulnerable to which of the following criticisms.

  16. Bolded statement question • This asks you to look at two specific sentences • May contain multiple arguments and conclusions, so BE CAREFUL to identify which evidence goes with which conclusion. • Very rare!

  17. Steps to attacking the question • Step 1: Identify the question • Step 2: Read, find conclusion, evidence, assumption, make sure you understand. • Step 3: Predict the answer • Step 4: Evaluate the answer choices • POE: Get rid of answers that are: • Not relevant • Obviously wrong
