To determine which sentence is written in the active voice, you can focus on the subject and the verb in each sentence. The active voice is used when the subject of the sentence performs the action expressed by the verb.

Let's analyze each sentence:

1. The meal was being cooked when I arrived home.
This sentence is written in the passive voice because the subject, "meal," is the receiver of the action "cooked," rather than the performer of the action.

2. Raisins are made from grapes.
This sentence is written in the passive voice because the subject, "raisins," is the receiver of the action "made," rather than the performer of the action.

3. The collaborative document is being shared with others.
This sentence is written in the passive voice because the subject, "collaborative document," is the receiver of the action "shared," rather than the performer of the action.

4. Somebody painted a colorful mural on the classroom wall.
This sentence is written in the active voice because the subject, "somebody," is the performer of the action "painted."

Thus, the sentence written in the active voice is:
4. Somebody painted a colorful mural on the classroom wall.
