EXPLANATIONS (All Answers Explained Below)
Correct answers are given as single words only. Explanations analyze auxiliary movement, structural triggers, and syntactic logic.
1 – had
“Barely” is a negative adverbial placed at the beginning for emphasis. This triggers subject–auxiliary inversion. In past perfect structures, the auxiliary must precede the subject. Without inversion, the sentence is grammatically incorrect in formal usage.
2 – did
“Not until” fronting causes inversion in the main clause, not in the subordinate clause. Because the verb is in the past simple, auxiliary support is required. The auxiliary precedes the subject to satisfy inversion rules.
3 – did
“Only then” functions as a restrictive fronted adverbial. When placed at the beginning, it triggers inversion in the main clause. Past simple requires auxiliary insertion.
4 – was
“So + adjective” fronted before the subject requires inversion when introducing a result clause. The linking verb moves before the subject to form emphatic inversion.
5 – did
“Never” is a negative time adverb placed initially. This structure requires auxiliary–subject inversion. Present or past simple requires auxiliary support.
6 – would
This is conditional inversion replacing “if.” The structure “Were + subject + to + verb” signals hypothetical condition. The result clause follows standard second conditional logic.
7 – did
“Not only” at clause-initial position triggers inversion in the first clause. The auxiliary precedes the subject. The second clause remains in normal word order unless parallel inversion is required stylistically.
8 – was
“Little” used as a negative determiner in fronted position triggers inversion. Passive construction requires the auxiliary to precede the subject.
9 – can
“Only by + gerund” at the beginning requires inversion in the main clause. Modal verbs move before the subject when inversion is triggered by restrictive fronting.
10 – had
“No sooner” requires past perfect inversion and is followed by “than.” It expresses immediate sequence. Auxiliary movement is mandatory.
11 – was
This is a cleft-like structure where the subject is a noun clause (“What impressed the panel most”). The verb must agree with the complement, which is singular. Therefore, singular agreement is required.
12 – should
“Under no circumstances” is a strong negative prepositional phrase. When fronted, it triggers inversion. Modal auxiliary precedes the subject.
13 – was
“Such” used in emphatic fronting requires inversion when followed by a result clause. The linking verb precedes the subject to create emphasis.
14 – do
“Hardly ever” is a negative frequency expression. When fronted, it triggers inversion. Present simple requires auxiliary support.
15 – that
This is an emphatic cleft structure: “It was … that …”. The conjunction introduces the focused element. Other forms cannot introduce a cleft clause correctly.
