❌ False
Explanation
Correct passive sentence:

“Been” is missing.

✅ True
Explanation
Past Continuous Passive:
was/were + being + V3
Active:
were cleaning
↓
Passive:
was being cleaned
Since the subject changes to:
the classroom (singular)
we use “was.”
✅ True
Explanation
Passive Voice:
should + be + V3
recycle
↓
recycled
The agent “people” is omitted because it is a generic subject, so the passive sentence remains correct without the phrase “by people.”
