The manager insisted that everyone submits the report by Friday. (Improve)

• A. submitted the report
• B. submit the report (Answer)
• C. will submit the report
• D. No improvement

'Insist that' takes the subjunctive mood — the bare form of the verb regardless of subject: 'that everyone submit the report'. Present indicative 'submits' is incorrect after verbs of demand or insistence.

It is essential that she is present at the ceremony. (Improve)

• A. was present
• B. be present (Answer)
• C. will be present
• D. No improvement

'It is essential/necessary/important that' triggers the subjunctive: 'that she be present', not the indicative 'is present'.

I wish I was taller so I could play basketball professionally. (Improve)

• A. were taller (Answer)
• B. am taller
• C. had been taller
• D. No improvement

'Wish' for an unreal present situation takes the subjunctive 'were' for all persons, not 'was'. Correct: 'I wish I were taller'.

If I was you, I would accept the job offer immediately. (Improve)

• A. were you (Answer)
• B. am you
• C. had been you
• D. No improvement

In hypothetical/unreal conditionals, 'were' is used for all subjects, including 'I': 'If I were you'. This is one of the most tested subjunctive forms in formal English.

The board recommended that the policy is revised before implementation. (Improve)

• A. was revised
• B. be revised (Answer)
• C. will be revised
• D. No improvement

'Recommend that' takes the subjunctive: 'that the policy be revised'. The indicative 'is revised' incorrectly states it as an established fact rather than a proposal.

If only she had told me earlier, I would have helped her. (Improve)

• A. would help her
• B. will have helped her
• C. No improvement (Answer)
• D. would have help her

'If only she had told me' correctly expresses regret about the past using the past perfect, and 'I would have helped' correctly completes the third conditional. No improvement needed.

Long live the king, may he rules with wisdom. (Improve)

• A. may he ruled
• B. may he rule (Answer)
• C. may he is ruling
• D. No improvement

Formulaic subjunctive expressions with 'may' (expressing a wish) take the bare infinitive: 'may he rule', not 'rules'. This optative subjunctive appears in formal or ceremonial English.

The judge demanded that the witness tells the whole truth. (Improve)

• A. told
• B. tell (Answer)
• C. will tell
• D. No improvement

'Demand that' is a strong subjunctive trigger, requiring the bare form 'tell' regardless of subject. 'Tells' is the common error students make by defaulting to normal third-person agreement.

It is imperative that every employee follows the new safety protocol. (Improve)

• A. followed
• B. follow (Answer)
• C. will follow
• D. No improvement

'It is imperative/vital/crucial that' is a fixed subjunctive trigger. Correct: 'that every employee follow the new safety protocol'. A high-difficulty pattern often missed because 'follows' feels grammatically natural with a singular subject.

Had she been informed in time, the accident might have been avoided. (Improve)

• A. might have avoid
• B. might avoided
• C. No improvement (Answer)
• D. might have being avoided

'Had she been informed' is a correctly inverted third-conditional 'if' clause, and 'might have been avoided' correctly completes it in the passive. No improvement — this tests whether students force an unnecessary correction on advanced inverted structures.
