The student wants to emphasise that Mauna Kea is taller than Mount Everest when measured from its base. Which choice most effectively uses relevant information from the notes to accomplish this goal?

Question

While researching a topic, a student has taken the following notes:
- Mount Everest's summit is 8,849 metres above sea level.
- Mauna Kea's summit is 4,207 metres above sea level.
- Mauna Kea's base sits on the ocean floor, about 6,000 metres below sea level.
- Measured from base to summit, Mauna Kea is about 10,200 metres tall.

Accepted Answer

A. Measured from its base on the ocean floor, Mauna Kea rises about 10,200 metres — more than Everest's 8,849 metres above sea level.. The goal is a specific comparison on a specific measure. Choice A uses the base-to-summit figure, 10,200 metres, and sets it directly against Everest's 8,849.

Answer

B. Mauna Kea's summit is 4,207 metres above sea level, far below Everest's 8,849. — This compares heights above sea level, on which Mauna Kea is shorter — it makes the opposite point.

Answer

C. Mount Everest's summit is 8,849 metres above sea level. — Only Everest is mentioned; there is no comparison.

Answer

D. Mauna Kea's base sits about 6,000 metres below sea level. — The depth of the base alone doesn't show Mauna Kea's total height or compare it with Everest.
