PrepTest 73, Logical Reasoning 1, Question 5
Summary
The content focuses on identifying and understanding the flaw in an argument within the context of a GRE question, specifically through the analysis of an argument about Lemaitre's theory.
- Understanding the flaw in an argument requires identifying the argument's conclusion and evidence.
- Lemaitre's theory suggests the universe began with a primeval atom explosion, which is evidenced by galaxies accelerating away from each other.
- The argument's flaw is the assumption that Lemaitre's theory is inadequate because another theory predicts the same outcome.
- The correct answer choice (D) highlights that one theory predicting data correctly does not invalidate an alternative theory.
- Other answer choices are dismissed because they misinterpret the argument's structure or the nature of its logical error.
