RC Question 17 Explanation

DISCUSSION: The author starts by criticizing the researchers’ theory. Then he adds a new theory of his own.

___________

1. CORRECT. The author criticizes the researchers in lines 41-52. He gives his own theory in lines 52-60.
2. This might describe paragraphs three and four together, but not paragraph four alone.
3. This would mean that the author ends by supporting the scientists’ hypothesis. That doesn’t happen, the author proposes his own, alternate theory.
4. Same as C.
5. There are only two explanations. The author rejects the researchers’ hypothesis, then introduces his own, second, explanation.
