Which sentence uses the active voice?

A. Breakfast is always served at 8 a.m. sharp.
B. Juice is included in all breakfast meals.
C. Customers are served as quickly as possible.
D. You can have anything that you find appealing.

I don't really understand active and passive voices but I think the answer is C) Customers are served as quickly as possible.

No. C is wrong.

Active voice is used when the subject is doing the action.
Customers are served . . .
Customers is the subject, but they are not doing the action. They're just sitting there waiting for the wait staff.

The subjects of each of these sentences is the first word. In which one are they doing the action?

After looking over Ms.Sue's link I feel as if the answer is D) You can have anything that you find appealing.

Because the customers are choosing their food/performing the action?

Yes, D is in the active voice.

You're on the right track! To determine whether a sentence uses the active voice or the passive voice, you need to identify the subject and the action being performed.

In the active voice, the subject of the sentence performs the action. In the passive voice, the subject of the sentence is being acted upon.

Let's break down the sentences:

A. "Breakfast is always served at 8 a.m. sharp."
This sentence is in the passive voice because the subject "breakfast" is not performing the action of serving; rather, it is being served.

B. "Juice is included in all breakfast meals."
Similar to sentence A, this sentence is in the passive voice. The subject "juice" is being included, not performing the action of including.

C. "Customers are served as quickly as possible."
This sentence is in the passive voice. The subject "customers" are being served, not actively serving.

D. "You can have anything that you find appealing."
This sentence is in the active voice. The subject "you" is performing the action of having.

Therefore, the sentence that uses the active voice is D) "You can have anything that you find appealing."
