Choose the part of the sentences which has an error :

Question

Accepted Answer

The correct option is 1:

The error lies in the word order of the first clause, "Scarcely he." This sentence uses the adverb "Scarcely" to introduce the clause, which is a negative adverb. In English grammar, when a sentence begins with a negative adverb (such as *Scarcely, Hardly, No sooner, Never, Rarely*), it requires inversion of the subject and the auxiliary verb. Since the main verb "entered" is in the Simple Past tense, the required auxiliary verb for inversion is "did." Therefore, the grammatically correct structure must be: Negative Adverb + Auxiliary Verb + Subject + Main Verb (base form). The corrected phrase should be "Scarcely did he enter," which follows the rule of inversion required for this compound sentence structure. Failing to use inversion is the common grammatical error identified here.

The incorrect option is 2:
"entered the room" contains the main verb in the Simple Past tense ("entered") and a direct object ("the room"). This part of the sentence is grammatically correct *if* it followed the inverted structure mentioned above (e.g., "Scarcely did he enter the room..."). In its current form, it is the consequence of the error in Option 1 but is not the error itself.

The incorrect option is 3:
"when he heard" correctly uses the subordinating conjunction "when" to introduce the second clause, which describes the action that immediately followed the first action. The Simple Past tense verb "heard" is also appropriate here to describe the simultaneous past event.

The incorrect option is 4:
"a loud noise outside" is the object and complement of the second clause. The noun phrase "a loud noise" and the adverbial phrase "outside" are correctly structured, providing context for what the subject heard.
