Question

the total phase of a particular solar eclipse can be seen: a. only over a region of earth within +/-23.5° of earth’s equator, that is, in the tropics. b. only within a specific narrow strip across earth’s surface. c. from anywhere on the sunlit hemisphere of earth. d. anywhere on the surface of earth.

Explanation:

A solar eclipse's total phase is visible only along a narrow path (the umbral path) across Earth's surface. Option a refers to the tropics (related to solar altitude for seasons, not eclipse paths). Option c (sunlit hemisphere) is too broad, and option d (anywhere on Earth) is incorrect as most of Earth won't see totality. Only option b matches the scientific understanding of a solar eclipse's total phase visibility.

Answer:

b. only within a specific narrow strip across Earth’s surface.
