Question

Quizplus · Accepted Answer

When other astronomers pointed their own telescopes toward Mars, they couldn't see the canals that Lowell claimed to have seen. This led to skepticism about his claims. Option A is partially correct, as the thick atmosphere of Mars was indeed a challenge to observing its surface through telescopes at the time, but it's not the main reason for skepticism toward Lowell's claims. Options B and C are false, as there is no evidence to suggest that Lowell suffered from poor vision or that his telescope was faulty.
