EXPLANATIONS (All Answers Explained Below)
Correct answers are given as single words only. Explanations focus on syntactic triggers, auxiliary movement, and structural logic.
1 – has
Negative adverbials such as “rarely” trigger subject–auxiliary inversion in formal English. The auxiliary must precede the subject. Without inversion, the structure is incorrect in formal style.
2 – was
“Not only” at the beginning of a clause requires inversion in the first clause. The auxiliary verb moves before the subject. The second clause does not invert unless parallel structure requires it.
3 – must
Fronted negative expressions like “under no circumstances” trigger inversion. Modal verbs move before the subject in formal prohibition structures.
4 – had
“Hardly” introducing a clause of sequence requires past perfect inversion. This structure emphasizes that one action was immediately followed by another.
5 – did
“Only after” + clause at the beginning triggers inversion in the main clause. The auxiliary “did” is inserted for emphasis in past simple contexts.
6 – do
“Seldom” is a negative-frequency adverb placed at the beginning for emphasis. Present simple requires auxiliary support for inversion.
7 – would
Conditional inversion replaces “if” in third conditional structures. “Had + subject + past participle” introduces a hypothetical past condition. The result clause remains standard third conditional.
8 – was
“So + adjective” fronting leads to inversion when followed by “that.” The linking verb precedes the subject.
9 – has
“Never before” is a negative time expression requiring inversion. Present perfect auxiliary precedes the subject.
10 – did
“Little” used as a negative adverb triggers inversion. Past simple requires auxiliary insertion.
11 – did
“Not until” fronted clause causes inversion in the main clause. The inversion applies after the time clause, not within it.
12 – was
“Such” used in emphatic fronting triggers inversion when followed by a clause expressing result. The linking verb precedes the subject.
13 – can
“Only by + gerund” at the beginning requires inversion in the main clause. Modal auxiliary precedes the subject.
14 – had
“No sooner” structure requires past perfect inversion and is followed by “than.” It expresses immediate sequence.
15 – was
This is a cleft structure functioning as subject complement agreement. “What the committee failed to consider” is a singular noun clause; therefore, singular verb agreement is required.
