June 2007, Logical Reasoning 2, Question 11
Summary
The content provides an in-depth analysis of how to approach necessary assumption questions on the GRE, focusing on dissecting arguments to identify unstated premises critical for the argument's validity.
- Necessary assumption questions require identifying unstated elements that an argument depends on.
- Understanding an argument involves breaking it down into its conclusion and supporting evidence.
- The example used illustrates an argument about increased mercury levels in fish, based on a study comparing seabird feathers from the 1800s to today.
- Key assumptions for the argument's validity include the absence of external factors affecting mercury levels in the feathers and the representativeness of the birds studied.
- The correct answer to a necessary assumption question is one that, if not true, would cause the argument to fall apart.
