Question

most birds play an active role as parents, sitting patiently on their eggs and feeding their young until they can leave the nest. however, certain birds, called brood parasites, lay their eggs in the nests of other birds and never return. some lay their eggs in the nests of other birds of the same species, but about one - percent lay their eggs in the nests of other species. the common cuckoo is an example of this kind of bird. to protect their own offspring, other birds learned to recognize the cuckoos eggs and ejected them from their nests. but, as an evolutionary response, cuckoos began to lay eggs that looked exactly like those of the host.
passage 2
there are no other birds that are as cruel as the ones known as brood parasites. these birds literally dump their eggs in other birds nests so they can avoid wasting their time and energy caring for their own young. their ruthless strategy is to trick other birds into raising their babies as their own while they go off happily. some other birds get wise to their tactics, but brood parasites are just as clever in response. some lay eggs that look just like the host eggs. that isnt terrible, but some tactics are much worse. i have heard of a common cuckoo baby pushing out the other eggs in the nest the minute it was born!
which author presents the information more effectively and why?
a. the second author because the evidence is specific and persuasive.
b. the first author because the evidence is nonbiased and anecdotal.
c. the second author because the evidence is anecdotal and opinionated.
d. the first author because the evidence is scientific and objective.

Explanation:

Passage 1 presents a more general and neutral - sounding description of brood parasites. Passage 2 uses phrases like "ruthless strategy" and "terrible" which are more opinion - laden and attempt to persuade the reader of the negative nature of cuckoos' behavior.

Answer:

D. The second author because the evidence is anecdotal and opinionated.
