Answer 1

During our time in New York City, we traveled by taxi, rode in the subway, and even took a ferry ride. 

The answer is took a ferry ride. 

The ferry ride fits the information to complete the sentence. This form of structure is called parallelism.

Parallelism is about creating the right phrase, sentence or clause to have a logical flow of the sentences. It also gives a clearer and relevant information. 

Answer 2

The correct answer is took a ferry ride.
The question is to make a parallel construction in this sentence. In order to do that, you need to use the same form of words. So, in the sentence above, all verbs are written in past simple form, which means that the verb which is missing has to have the same form.
