Combine the following sentences into one sentence using an adverb clause of comparison:
Our new ceiling fan is quiet. The old one was not so quiet.
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → Our new ceiling fan is quieter than the old one was.
Adverb clause of comparison:
- When one thing has more of a quality, we use the -er form of the describing word. The clause of comparison after it begins with than.
- “The old one was not so quiet” means the new fan is quieter. So “than the old one was” comes after “quieter”.
Why the Other Options are Incorrect?
Option 1: Our new ceiling fan is as quiet as the old one was. — Incorrect. “As quiet as” says the two fans are equally quiet. The given sentences say the old fan was less quiet. Example: Ravi is now as tall as his father is.
Option 3: Our new ceiling fan is quieter as the old one was. — Incorrect. After the -er form “quieter”, the clause must begin with “than”, not “as”.
Option 4: Our new ceiling fan is quieter than the old one it was. — Incorrect. In the clause, “the old one” is already the subject of “was”. The extra “it” gives the verb a second subject.
