Answer:
The answer is compare, contrast, contrast, compare.
Explanation:
I had to rearrange the question (because I've done it before) to understand it.
Determine whether each sentence from A Black Hole Is NOT a Hole compares or contrasts.
A black hole works something like that whirlpool.
compares / contrast
However, near a black hole, gases and dust and stars encounter its tug.
compares / contrast
But anything inside this zone stays in the black hole's place in space forever.
compares / contrast
It just (sort of) acts like one.
compares / contrast
The first sentence- compare
The second sentence- contrasts
The third sentence- contrasts
The last one- compare.
