Final answer:
Sentence (a) 'The team collaborates effectively, communicates transparently, and delivers consistently' and sentence (c) 'She wanted to travel not only to explore new cultures but also to learn different languages' display parallel structure. Parallelism is used to maintain consistency and balance in a sentence's elements.
Step-by-step explanation:
Parallel structure, also known as parallelism, is a stylistic device used to enhance the readability and flow of writing by ensuring that similar parts of sentences are expressed in a consistent manner.
Among the sentences provided, the following demonstrate parallel structure:
- The team collaborates effectively, communicates transparently, and delivers consistently.
- She wanted to travel not only to explore new cultures but also to learn different languages.
The first sentence, (a), uses a series of verbs followed by adverbs, creating a pattern that is consistently maintained across the list. The third sentence, (c), establishes parallelism by using a correlative conjunction 'not only... but also' followed by infinitive phrases to maintain a balanced structure.
Sentence (b) and (d) do not exhibit parallel structure because the elements within their lists are not consistent in terms of grammatical form.
