Answer:

Explanation:
The active voice puts emphasis on the noun (person/object) performing the verb/action.
The structure is:
- <u>Subject</u>, action, <em>object</em>
An example is:
- <u>The cat</u> ate the <em>food</em>.
The passive voice places the emphasis on the noun receiving the action.
The structure is:
- <em>Object</em>, action, <u>subject </u>
The same example from above in the passive voice is:
<em>The food </em>was eaten by the <u>cat.</u>
<u />
The sentence were are given is:
The entire house was painted by Tom.
Identify the subject, action, and object
- Subject: Tom
- Action: Painted
- Object: The house
Therefore, the order is object (the house), action (painted), subject (Tom). This must be the passive voice. The house is receiving the action of being painted .
