Answer 2

It appears that you have provided a set of sentences and rules for forming past passive sentences. Let me break down the rules and provide an explanation:

1. Active Verb Structure:
   • Active verb: In the active voice, you start with an active verb that describes the action being performed.
   • Object: The direct object is the receiver of the action.
   • Subject: The subject is the entity performing the action.

Example Sentences in Active Voice:

• People used the fur.
• Humans hunted mammoths.
• Hunters didn't cause the mass extinction.

2. Passive Verb Structure:
   • Subject: In passive voice, the subject of the sentence receives the action.
   • "be" + Past Participle: The verb "be" (conjugated based on the tense, such as "was" or "were") is followed by the past participle of the active verb.
   • "by" + Agent: Optionally, you can mention the agent (the entity performing the action) using "by."

Example Sentences in Passive Voice:

• The fur was used by people.
• Mammoths were hunted by humans.
• The mass extinction wasn't caused by hunters.

So, in summary, to form past passive sentences, you start with an active verb, change the subject to the receiver of the action, use the appropriate form of "be" (e.g., was, were), add the past participle of the active verb, and optionally include the agent with "by."
