read the question carefully and select the best answer.
the following passage (paragraph 9) adds to the development of the entire article mainly by ______.
technically, this delivers a lot of energy into the earth, but its spread out over a large enough area that it doesnt do much more than leave footprints in a lot of gardens. a slight pulse of pressure spreads through the north american continental crust and dissipates with little effect. the sound of all those feet hitting the ground creates a loud, drawn - out roar which lasts many seconds.
a. explaining why all the people landing at the same time has little effect
b. suggesting that the people are all jumping in gardens
c. describing the sights and sounds that accompany such a massive, coordinated jump
d. suggesting that the jump would have had a greater effect if the people had gathered more closely together

Explanation:

The passage focuses on breaking down why the coordinated jump has minimal impact: it explains the energy is spread over a large area, pressure dissipates through the crust, and describes the resulting sound. This directly aligns with explaining the lack of effect. Option B is incorrect as the passage does not suggest people are jumping in gardens. Option C is wrong because the sights/sounds are not the main focus, just a minor detail. Option D is incorrect as the passage does not discuss a hypothetical more gathered group's effect.

Answer:

A. explaining why all the people landing at the same time has little effect
