Question

which sentence correctly uses parallel structure?
the boss wants to know who can take the late shift tonight, open tomorrow morning, and who can work on the holiday.
the boss wants to know who wants the late shift tonight, who can open tomorrow morning, and if you will work on the holiday.
the boss wants to know who can take the late shift tonight, who can open tomorrow morning, and who can work on the holiday.
the boss wants to know who can take the late shift tonight, who can open tomorrow morning, and which of us wants to work on the holiday.

Explanation:

Parallel structure requires consistent grammatical form for linked items in a list. The correct option uses the repeated structure "who can [verb phrase]" for all three items in the boss's request, creating grammatical consistency. Other options mix structures (e.g., missing "who can" in the second item, switching to "if you will" or "which of us wants").

Answer:

C. The boss wants to know who can take the late shift tonight, who can open tomorrow morning, and who can work on the holiday.
