Question

Quizplus · Accepted Answer

Parallel ideas are those that have the same level of importance within a sentence. In order to show this, we need to use parallel structure. Depending on the sentence, we may need to use parallel words, phrases, or clauses (this means that the words, phrases, or clauses use the same grammatical structure). Typically, we join parallel structures with conjunctions such as "and" and "or."
In this example, the form of the first verb (-ing) must be parallel to the second (-ing).
Heavy drinking and partying are common among the tourists who visit the island.
All of the other options use different forms of the verbs connected by the conjunction, so they do not have parallel structure.
