Answer:
D. None of Above
Explanation:
The answer to the question is D because:
The wouldn't make sense in this sentence. The would make a grammatical error. The answer can not be option A.
An would not make sense in the sentence. An would be used when you are talking about a singular item. Independence is plural. It can not be option B.
Those would not make sense in the sentence. Those is referring to many people, not something that is an idea. The answer is not option C.
That means the answer must be option D.
The answer is broke off. Flames glided in the river, small green flames, red flames, white flames, pursuing, overtaking, joining, crossing each other—then separating slowly or hastily.
'broke off' indicates that the person is getting out of a certain situation. Since it's followed by another event that seems different compared to the things that he see/feel before he broke off, we can conclude that the event is not happening in the present time.
