Question

The author of the passage would be most likely to agree with which of the following statements about the Milankovitch theory?

• A. It is the only possible explanation for the ice ages.
• B. It is too limited to provide a plausible explanation for the ice ages, despite recent research findings.
• C. It cannot be tested and confirmed until further research on volcanic activity is done.
• D. It is one plausible explanation, though not the only one, for the ice ages.
• E. It is not a plausible explanation for the ice ages, although it has opened up promising possibilities for future research.

Answer 1

The correct option is D It is one plausible explanation, though not the only one, for the ice ages.

From the last few lines of the passage we can infer that though Milankovtich's theory is testable, it is not the only theory that explains the ice-ages. The use of the word 'advantage' with respect to Milankovitch's theory suggests that it is not the only theory regarding the ice ages. In this context, option D is the correct answer.
