Identify the part of the sentence that contains an error.
No sooner had I opened the door / when the rain, heavy and sudden, rushed in / making us shiver from head to toe.
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → when the rain, heavy and sudden, rushed in
"No sooner" is always followed by "than", never by "when". The phrase means that one thing happened at once after another. So "when" in the second part must be "than".
Option 1: No sooner had I opened the door — No error. When a sentence begins with "No sooner", the helping verb comes before the subject. So "had I opened" is right.
Option 2: when the rain, heavy and sudden, rushed in — Error. “when” should be “than”.
Option 3: making us shiver from head to toe — No error.
Corrected: No sooner had I opened the door than the rain, heavy and sudden, rushed in, making us shiver from head to toe.
