Answer:
When we correct the subject-verb agreement, we have:
- The gorilla at the zoo, along with the chimpanzee, is allowed to play in the new fallen snow.
Explanation:
It may seem that the subject of the original sentence is plural, but it is actually singular. The verb only refers to the gorilla. The chimpanzee is mentioned in an appositive phrase, which just adds extra information to the sentence.
If we want to use the verb "are", we should remove the appositive phrase and place "chimpanzee" in the same subject as "gorilla":
- The gorilla and the chimpanzee at the zoo are allowed to play in the new fallen snow.
However, since that is not the case, the correct sentence with the original structure is:
- The gorilla at the zoo, along with the chimpanzee, is allowed to play in the new fallen snow.
