Please help I am not doing it correctly

REVISED: The agency investigated the matter.

REVISED: Economists have failed to define full employment.

ORIGINAL: The agency conducted an investigation into the matter.

REVISED: The agency investigated the matter.

ORIGINAL: Attempts by economists at defining full employment have met with failure.

REVISED: Economists have failed to define full employment.

Sure, I can help you with that!

To rewrite the sentence into the active voice, we need to identify the subject of the sentence and put it before the verb. Here's how you can complete the blanks:

REVISED: The agency conducted the investigation into the matter.

In this case, "The agency" is the subject performing the action, which is "conducted." The object "the investigation into the matter" remains the same, but the sentence is now in the active voice.

REVISED: Economists have failed to define full employment.

In this sentence, "Economists" is the subject and "have failed" is the verb. The object "to define full employment" remains the same. Again, the sentence is now in the active voice.

Remember, in the active voice, the subject performs the action, while in the passive voice, the subject receives the action. In these revisions, we've made the subjects ("The agency" and "Economists") the active part of the sentence. I hope this clears up any confusion! Let me know if you have any further questions.
