Identify Spot the error in the given sentence. Had I knew the answer, I would have raised my hand.
Show answer & explanation
Correct answer: B
Explanation
The sentence uses an inverted structure for a third conditional sentence, which implies a hypothetical situation in the past. The correct structure requires the past perfect tense (had + past participle) in the 'if' clause. The past participle of "knew" is "known". Therefore, the correct phrasing should be "Had I known the answer".
