which sentence or sentences have correct parallel structure?\nalmost all states place both nighttime-driving…

Brief Explanations:

To determine parallel structure, we check if the items connected by "and" (or "both...and") have the same grammatical form. In the second sentence, "nighttime - driving restrictions" and "passenger restrictions" are both noun phrases (with the structure "type - of - restriction + restrictions"). In the first sentence, "nighttime - driving" is a noun - like modifier and "passenger restrictions" is a noun phrase, so their structures are not parallel. The second sentence has correct parallel structure as both elements are noun phrases with the same structure (modifier + "restrictions").

Answer:

The sentence with correct parallel structure is: Almost all states place both nighttime - driving restrictions and passenger restrictions on newly licensed teen drivers.
