Had the government invested (A) / in better infrastructure earlier, (B) / the cities would not face (C) / such severe flooding today. (D)

• A. Had the government invested
• B. in better infrastructure earlier,
• C. the cities would not face (Answer)
• D. No error

MIXED CONDITIONAL TRAP: The 'if' clause uses past perfect ('had invested' — Type 3), but the result clause 'would not face' (present conditional) is correctly used here for a mixed conditional linking a past condition to a present result. Actually, this IS correct as a mixed conditional. No error. Answer is D.

Unless you will not (A) / submit the form (B) / by tomorrow, (C) / your application will be rejected. (D)

• A. Unless you will not (Answer)
• B. submit the form
• C. by tomorrow,
• D. No error

DOUBLE NEGATIVE WITH 'UNLESS': 'Unless' already carries a negative meaning ('if...not'). Adding 'not' creates a double negative that reverses the meaning. Correct: 'Unless you submit the form' (remove 'not') OR 'If you do not submit the form'. This is a classic exam trap.

Provided that all members (A) / are present at the meeting, (B) / the resolution can be passed (C) / with a simple majority. (D)

• A. Provided that all members
• B. are present at the meeting,
• C. the resolution can be passed
• D. No error (Answer)

CLEAN SENTENCE: 'Provided that' is a conditional conjunction used correctly here. The verb 'are' in a present conditional clause is correct. The main clause with 'can be passed' is also correct. No error — tests whether students penalise 'provided that' unnecessarily.

I wish I (A) / would have known (B) / about the scholarship opportunity (C) / before the deadline passed. (D)

• A. I wish I
• B. would have known (Answer)
• C. about the scholarship opportunity
• D. No error

'I wish' for an unreal past situation takes past perfect: 'I wish I had known'. 'Would have known' is incorrect after 'wish'. Students confuse 'I wish...would' (for future wishes/complaints) with 'I wish...had' (for past regrets). Correct: 'I wish I had known'.

Even if the proposal (A) / is rejected by the committee, (B) / the management will continued (C) / to explore alternative solutions. (D)

• A. Even if the proposal
• B. is rejected by the committee,
• C. the management will continued (Answer)
• D. No error

'Will' is a modal verb and must be followed by the bare infinitive: 'will continue', not 'will continued'. Correct: 'the management will continue'. The 'ed' ending on 'continued' after 'will' is an elementary error hidden within a complex conditional sentence.

Suppose if (A) / the negotiations fail, (B) / what contingency plan (C) / does the team have? (D)

• A. Suppose if (Answer)
• B. the negotiations fail,
• C. what contingency plan
• D. No error

REDUNDANCY: 'Suppose' and 'if' both introduce conditional situations. Using both together is redundant. Correct: either 'Suppose the negotiations fail' or 'If the negotiations fail'. 'Suppose if' is a very common Indian English error tested in competitive exams.

The legislation will come into effect (A) / as soon as it will be (B) / ratified by (C) / the upper house of Parliament. (D)

• A. The legislation will come into effect
• B. as soon as it will be (Answer)
• C. ratified by
• D. No error

TIME CLAUSE WITH FUTURE: In subordinate clauses of time ('as soon as', 'when', 'until'), present tense replaces future tense. Correct: 'as soon as it is ratified'. 'Will be' in a time clause is a high-frequency exam error — students instinctively put 'will' because the action is in the future.

She behaves as if (A) / she knows everything (B) / about the subject, (C) / which irritates her colleagues. (D)

• A. She behaves as if
• B. she knows everything (Answer)
• C. about the subject,
• D. No error

'As if' introduces an unreal/hypothetical situation, requiring subjunctive mood (past tense for unreality): 'as if she knew everything'. Using simple present 'knows' implies it is a real fact, which contradicts the hypothetical nature of 'as if'. Correct: 'as if she knew'.

In case you require (A) / any further clarification, (B) / please do not hesitate (C) / to contact our support team. (D)

• A. In case you require
• B. any further clarification,
• C. please do not hesitate
• D. No error (Answer)

CLEAN SENTENCE: 'In case you require' (present simple in conditional clause) is correct. 'Do not hesitate to contact' is also correct. No error. This tests whether students mistakenly change 'require' to 'will require' or mark the sentence as erroneous.

The manager warned (A) / that if production targets (B) / are not met this quarter, (C) / several positions may eliminated. (D)

• A. The manager warned
• B. that if production targets
• C. are not met this quarter,
• D. several positions may eliminated (Answer)

MODAL + PASSIVE: 'May' is a modal verb and must be followed by 'be' before the past participle for passive voice: 'may be eliminated'. 'May eliminated' omits the auxiliary 'be', making it grammatically incomplete. The complexity of the surrounding clause hides this straightforward omission.
