Scarcely … she entered the room when the phone rang.

Analyze the question

The sentence begins with "Scarcely," a negative adverb placed at the start. This triggers inversion (the auxiliary verb comes before the subject). The sentence also describes two past events, where one happened immediately after the other.

Explain the concept

The structure "Scarcely + had + subject + past participle ... when + simple past" is used to show that one past action was followed immediately by another.

• Scarcely had she entered the room when the phone rang.
• Similar patterns: "Hardly had... when..." and "No sooner had... than..."

The first action (entering the room) happened before the second (the phone ringing), so it takes the past perfect tense (had + past participle). The second action uses the simple past (rang).

Solution

1. "Scarcely" at the start of the sentence requires inversion: auxiliary + subject.
2. The first action is completed before the second, so we need the past perfect: had + entered.
3. Check the options: • A. did: "Scarcely did she entered" is wrong, because "did" would need the base form "enter" and does not fit the "scarcely... when" pattern. • B. has: present perfect, which clashes with the past tense "rang". • C. does: present tense, which does not fit. • D. had: past perfect, which is correct.

Correct sentence: Scarcely had she entered the room when the phone rang.

Tip: Remember the pair "Scarcely/Hardly had ... when" and "No sooner had ... than". If you see any of these openers in JAMB, go straight for "had". Also note that "scarcely" and "hardly" go with when, while "no sooner" goes with than.
