person b is representing a person at noon. why would person b see the text cut off at noon?
a. sunlight traveling to person b is traveling through more atmosphere, so longer wavelengths of color are text cut off
b. sunlight traveling to person b is traveling through less atmosphere, so longer wavelengths of color are text cut off
c. sunlight traveling to person b is traveling through text cut off

Explanation:

Question 1

The Earth rotates on its axis (spins) and revolves around the Sun. Option A has "Revolves" (around Sun) and "spins" (on axis), which matches. Option B's "Orbit" is a noun, not a verb. Option C swaps rotate and revolve. Option D has incorrect terms.

From space, about 50% of the Moon is always illuminated by the Sun (due to its spherical shape and Sun’s light direction). 25% is too little, 75% and 100% are incorrect.

At noon, the Sun is overhead, so sunlight travels through less of Earth’s atmosphere. Shorter wavelengths scatter more, but longer wavelengths (like yellow/orange) reach better? Wait, no—at noon, the path is shorter, so less atmosphere means less scattering. Option B says "less atmosphere" and "longer wavelengths" (though maybe phrasing, but key is path length: noon has shorter path (less atmosphere) than sunrise/sunset. So Option B’s "less atmosphere" is correct (vs A’s "more").

Answer:

A. Revolves, spins
