Question

select the correct answer from each drop-down menu.
read the sentence from paragraph 2.

at the heart of the mitigation project are two goals: to create more habitat connectivity for diverse species of wildlife and
to keep animals from becoming roadkill.

how does the author use the phrase \at the heart of\ to clarify ideas in the passage?

the phrase \at the heart of\ means
the author uses this phrase to clarif
the most important part.
the final pieces to a project.
the goals that are at the physical center.

Explanation:

For the first drop - down, the phrase "at the heart of" in the context of a project (mitigation project here) means the most important part. The option "the final pieces to a project" is incorrect as "at the heart of" doesn't refer to final parts. The option "the goals that are at the physical center" is also incorrect as it's a metaphorical use, not about physical location. For the second part (though the full question about how the author uses it is a bit unclear from the given, but based on the first part), the correct meaning of "at the heart of" is "the most important part".

Answer:

The phrase "at the heart of" means the most important part.
