Select the correct option: It was imperative that the document ___ signed before the close of business.
- (a)will be
- (b)was
- (c)be
- (d)had been
Answer
Why
Correct — C. The trigger is It was imperative that. Adjectives of necessity such as imperative, essential and vital take the mandative subjunctive: the bare verb, with no tense and no agreement.
So the clause keeps be even though the main verb was is past:
It was imperative that the document be signed before the close of business → option (c).
Why the others are wrong
- (a)will be — Will be is a future indicative, a prediction. The clause after imperative states a requirement, and will also clashes with the past-tense was.
- (b)was — Was is the ordinary past indicative, which reports a fact. After imperative that, formal English states the requirement with the bare verb be, whatever the tense of the main clause.
- (d)had been — Had been is the past perfect, which places the signing before some other past moment. The deadline is already given by before the close of business, and the mandative clause takes the bare verb.
Concept
The mandative subjunctive follows words of demand, requirement or proposal: verbs such as insist, demand, suggest and recommend, and adjectives such as imperative, essential, vital and necessary.
Its verb is the bare infinitive, with no -s for he or she and no change for past time: 'She insisted that he go.' 'It is essential that everyone be present.'
In the passive the pattern is be + past participle: that the document be signed.
British English also allows should here: It was imperative that the document should be signed. Should be is not among the options, and be is the form the key marks.
Key facts
- Imperative, essential, vital and necessary + that take the bare verb: that he be, that she go.
- The mandative subjunctive does not change for past time: It was imperative that the document be signed.
- In the passive the pattern is be + past participle: that the document be signed.
- British English also uses should + verb here: that the document should be signed.

Common traps
- Backshifting to was because the main verb was is past, when the subjunctive keeps be
- Choosing had been because the signing had to come before a deadline, when before the close of business already says that
The same bare-verb rule after insist is keyed at 12 Sep 2025, 16:00, English Q.20, where 'She insisted me to take the medicine' becomes that I take the medicine.
The contrast case is 19 Sep 2024, 12:30, English Q.7: think does not take the subjunctive, so 'she be completely safe' is keyed as is completely safe.
