Key Concepts for Strengthening Questions
Understand the Argument Structure:
Identify the conclusion, premises, and any assumptions in the argument.
Recognize the logical flow from premises to conclusion.
Identify Weaknesses:
Look for gaps or weaknesses in the argument that could be addressed to make it stronger.
Consider what additional information or evidence would bolster the conclusion.
Focus on Assumptions:
Strengthening often involves supporting the assumptions that underlie the argument.
Think about what must be true for the conclusion to logically follow from the premises.
Evaluate Answer Choices:
Choose the option that provides new information or evidence that directly supports the argument.
Avoid choices that introduce irrelevant information or weaken the argument.
Strategies for Strengthening Questions
Read the Argument Carefully:
Ensure you fully understand the argument before looking at the answer choices.
Pay attention to the logic and any implicit assumptions.
Predict the Answer:
Before looking at the options, try to predict what kind of information would strengthen the argument.
This helps you focus on the most relevant choices.
Eliminate Irrelevant Choices:
Discard options that do not directly address the core of the argument or its assumptions.
Focus on choices that provide clear, logical support.
Practice with Real Questions:
Use official GMAT practice materials to get familiar with the types of arguments and questions you'll encounter.
Analyze the explanations for correct and incorrect answers to understand the reasoning behind them.
Example Approach
Consider an argument like: "All students who take music lessons perform better academically. Therefore, schools should require music lessons for all students."
Identify the Conclusion: Schools should require music lessons for all students.
Identify the Premise: Students who take music lessons perform better academically.
Assumption: Taking music lessons directly causes better academic performance.
To strengthen this argument, you might look for evidence that directly links music lessons to improved academic performance, such as studies showing a causal relationship.
