What is the main idea of the third paragraph?
The correct answer is B.
(A) Incorrect. While the opening line states that “Squirrels prey on robin eggs and baby robins,” the paragraph goes on to list other animals which prey on, or hunt, robins and their eggs. So the main idea does not center on squirrels, but rather on animals which prey on robins and their eggs.
(B) Correct. In the third para ,the author lists the animals which prey on baby robins and robin eggs. Further he lists animals which prey on adult robins.Therefore, the entire paragraph is centered on animals which prey on robins.
(C) Incorrect. There is no mention that the adult robins do not care for their young.
(D) Incorrect. The paragraph states that “Crows prey on baby robins and robin eggs. Hawks prey on adult robins.” However, there is no mention that crows prey on adult robins or that hawks prey on baby robins and robin eggs.
