Explanation:

• Question 10: The Moon's diameter is about \(1/4\) of Earth's, not \(1/16\).
• Question 11: African - American "computers" (human calculators) started at NASA's Langley in the 1940s.
• Question 12: If the Moon disappeared, Earth's oceans would have much larger, destructive tides. The Moon's gravity significantly affects tides.
• Question 13: An asteroid is a relatively small, inactive, rocky body (not metallic with an atmosphere) that orbits the Sun.

• Question 11: B. 1940's
