Question

question 10
some bird species dont raise their own chicks. instead, adult females lay their eggs in other nests, next to another bird species own eggs. female cuckoos have been seen quickly laying eggs in the nests of other bird species when those birds are out looking for food. after the eggs hatch, the non - cuckoo parents will typically raise the cuckoo chicks as if they were their own offspring, even if the cuckoos look very different from the other chicks.
which choice best describes the function of the underlined sentence in the text as a whole?
a) it introduces a physical feature of female cuckoos that is described later in the text.
b) it describes the appearance of the cuckoo nests mentioned earlier in the text.
c) it offers a detail about how female cuckoos carry out the behavior discussed in the text.
d) it explains how other birds react to the female cuckoo behavior discussed in the text.

Explanation:

The underlined sentence gives a specific way female cuckoos lay eggs in other birds' nests, which is a detail about the egg - laying behavior discussed in the text. It doesn't introduce a physical feature, describe cuckoo nests' appearance, or explain other birds' reactions.

Answer:

C. It offers a detail about how female cuckoos carry out the behavior discussed in the text.
