Question

part a: which two of the following statements should be included in an objective summary of the article?
a. the distance between a satellite and the object it is orbiting varies due to the shape of the orbit.
b. the use of man - made satellites to take pictures of earth from space presents a privacy concerns to all humans.
c. the earth’s consistent and circular orbit around the sun keeps the length of earth days regular.
d. man - made satellites pose a serious threat to the environment that natural objects in space do not.
e. a satellite is in orbit as long as it is making a recurring elliptical path around another object.
f. the shapes of the paths that satellites take around an object allow them to stay in motion.

Explanation:

An objective summary presents facts without personal opinions.

• Option A: The distance between a satellite and the object it is orbiting varies due to the shape of the orbit. This is a factual statement about satellite - orbit dynamics.
• Option F: The shapes of the paths that satellites take around an object allow them to stay in motion. This is a factual statement about satellite motion based on orbital path shapes.
• Option B: The use of man - made satellites to take pictures of Earth from space presents a privacy concern to all humans. This is an opinion as not all humans may share this view.
• Option C: The Earth’s consistent and circular orbit around the sun keeps the length of Earth days regular. The Earth's orbit is elliptical, not circular, so this is a false statement.
• Option D: Man - made satellites pose a serious threat to the environment that natural objects in space do not. This is an opinion as it requires value - judgment on the threat level.
• Option E: A satellite is in orbit as long as it is making a recurring elliptical path around another object. While the path is often elliptical, this is more of a description of orbital mechanics rather than a key, objective summary point for a general article summary.

Answer:

A. The distance between a satellite and the object it is orbiting varies due to the shape of the orbit.
F. The shapes of the paths that satellites take around an object allow them to stay in motion.
