PART A: Which statement best expresses the central idea of the text? Book: Will we know alien life when we see it? Recognizing life on other worlds requires wiggle room in the definition of ‘life'

A.

Astrobiologists know that life exists on other planets, but they don’t think that we will ever be able to recognize or study it.

B.

While astrobiologists suspect that there may be alien life on other planets, they believe it might exist or develop in a way that is unfamiliar to us.

C.

In order to identify and study life on other planets, scientists must better understand the strange life hiding on our own planet first.

D.

Astrobiologists’ definition of living and nonliving things are too vague and need to be made more specific before they can identify living things on other planets.
