Need help changing passive voice to an active one....

Iowa’s state lottery bill was approved by the Senate in a close vote taken this morning.

Is this correct?

The Iowa Senate approved the state lottery bill in a close vote taken this morning.

Right.

To change this sentence from passive voice to active voice, you need to identify the subject, verb, and object in the original sentence, and then rearrange the sentence to make the subject the doer of the action. Here's how you can do it:

Original sentence (passive voice): Iowa’s state lottery bill was approved by the Senate in a close vote taken this morning.

Identify the subject, verb, and object:
Subject: Iowa’s state lottery bill
Verb: was approved
Object: by the Senate

Rephrase the sentence in active voice:
The Senate approved Iowa’s state lottery bill in a close vote taken this morning.

In the active voice sentence, the subject (the Senate) is now performing the action (approved) on the object (Iowa’s state lottery bill).
