Choose the option that changes the given sentence into a simple sentence without changing its meaning:
It is certain that the new footbridge at the station will open before the monsoon.
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → The new footbridge at the station is certain to open before the monsoon.
Changing a that-part into “to” + verb:
- The given sentence starts with “It is certain that”. The that-part has its own subject and verb: “the new footbridge ... will open”.
- In the simple sentence, “the new footbridge at the station” comes to the front and “will open” becomes “to open”: is certain to open. The meaning stays the same.
Why the Other Options are Incorrect?
Option 1: It is certain the new footbridge at the station will open before the monsoon. — Incorrect. This is still a complex sentence. Only “that” has been dropped. The part “the new footbridge at the station will open” still has its own subject and verb.
Option 2: The new footbridge at the station is likely to open before the monsoon. — Incorrect. This changes the meaning. “Likely” means “probably”, but the given sentence says the opening is certain.
Option 4: The new footbridge at the station is certain of opening before the monsoon. — Incorrect. The option says “certain of opening”. “Certain of” tells what a person feels sure about. A footbridge cannot feel sure, so the meaning changes.
