June 2007, Logical Reasoning 2, Question 21

The content provides an in-depth analysis of a GRE question focused on weakening an argument, highlighting the importance of understanding the argument's assumptions, conclusion, and evidence.
  • Identifying the argument's conclusion and supporting evidence is crucial before attacking its assumptions.
  • The argument assumes a cost-benefit analysis and makes a prediction about the future, both of which are common targets for weakening.
  • The correct answer choice weakens the argument by presenting an alternative that challenges the assumed trade-off between meat production and grain consumption.
  • Irrelevant answer choices focus on aspects like willingness to pay, nutritional value, or specific conditions not directly tied to the argument's core assumptions.
  • The process of elimination and understanding the argument's structure are key strategies in selecting the correct answer.
