Question

Choose the grammatically correct sentence.

• A. Hardly had the lecture begun when the fire alarm rang.
• B. Hardly had the lecture begun than the fire alarm rang.
• C. Hardly the lecture had begun when the fire alarm rang.
• D. Hardly had begun the lecture when the fire alarm rang.

Hint:

Remember the fixed pairs: No sooner–than, Hardly–when, Scarcely–when. Mixing them is a common competitive-exam trap.

Answer 1

The Correct Option is A

Concept: This question tests inversion structures and correlative conjunctions, which are frequently used in difficult grammar sections. The structure involving Hardly follows a fixed grammatical pattern: \[ \text{Hardly had + Subject + Past Participle + when} \] Students often confuse when with than, which creates a common examination trap.

Step 1: Recall the standard structure. The accepted grammatical construction is: \[ \text{Hardly} \dots \text{when} \] Similarly, \[ \text{No sooner} \dots \text{than} \] The two structures must not be mixed.

Step 2: Examine Option (A). \[ \text{Hardly had the lecture begun when the fire alarm rang.} \] This perfectly follows: \[ \text{Hardly + inversion + when} \] Hence it is grammatically correct.

Step 3: Examine Option (B). The sentence uses: \[ \text{Hardly} \dots \text{than} \] which is grammatically incorrect.

Step 4: Examine Option (C). The inversion structure is missing. The placement of auxiliary verb is incorrect. Hence option (C) is incorrect.

Step 5: Examine Option (D). The word order violates English syntax rules. Therefore option (D) is incorrect.

Step 6: Final conclusion. Only option (A) follows both inversion and conjunction rules correctly. \[ \boxed{\text{Option (A)}} \]
