Answer 1

The correct answer is d. The recent birth of a Sumatran rhinoceros in a Cincinnati zoo, the first birth in captivity for that species in over a century, is.

Step-by-step explanation:

The idea can be written again using a relative clause, which is used to define the noun that is before in the sentence. In this example, the noun or subject refers to the recent birth of the rhinoceros. Since the object being described is the same, it is ok to omit the relative pronoun (which or that for the subject recent birth) and divide the sentence with a coma to indicate the beginning and ending of the relative clause.
