Detailed Explanations (All Answers Analyzed Together)
Question 1
Structural Reason
“Proposed that” triggers the mandative subjunctive.
Structure:
that + subject + base verb (be).
Correct:
“the experiment be suspended.”
Meaning Logic
This expresses recommendation, not factual description.
Why B Fails
“Is suspended” states a present fact.
Why C Fails
“Was suspended” incorrectly implies completed action.
Rhetorical Effect
Maintains institutional neutrality — common in ethics reports.
Exam Note
IELTS academic writing often uses this pattern in formal proposals.
Question 2
“Vital that” → subjunctive base form.
“Be informed” (passive subjunctive).
“Is” or “was” incorrectly impose tense marking.
Academic and legal writing strongly prefer this structure over “should be.”
Question 3
Formal inversion structure:
Should + subject + base verb.
Full equivalent:
If any irregularities should arise…
“Arises” breaks base form requirement.
“Arose” shifts to past tense incorrectly.
Question 4
Negative subjunctive:
that no material be disclosed
“Is” and “was” turn clause into factual statement rather than prohibition.
Common in legal English.
Question 5
Correct structure:
Were the allegations substantiated…
After inversion, “substantiated” functions as complement (past participle adjective).
“To be” or “being” disrupt formal inversion.
Question 6
“Insisted that” → subjunctive.
“Be verified.”
“Are” and “were” imply factual states rather than demanded action.
Question 7
Fixed expression:
“If it were not for…”
Subjunctive “were” used regardless of subject.
“Was” is informal spoken alternative but weaker in academic register.
Question 8
“Recommend that” → subjunctive passive.
“Be sent.”
“Are sent” = fact.
“Were sent” = past fact.
Question 9
Fixed formula:
“So be it.”
Ceremonial subjunctive.
“Is” and “was” are grammatically incompatible.
Question 10
Legal modality:
“May terminate.”
This is not subjunctive but formal modal usage.
“May terminates” = double marking error.
“Terminates” lacks modal precision.
Legal drafting relies on modal verbs for clarity.
Question 11
Inverted third conditional:
Had the evidence been presented…
Only “been” fits grammatically.
Question 12
“Crucial that” → subjunctive.
“Be present.”
“Is” states fact; “was” shifts time reference incorrectly.
Question 13
“Suggested that” → subjunctive.
“Be revised.”
Again, formal academic tone.
Question 14
Inverted conditional:
Should the proposal be rejected…
Base verb required.
Question 15
“As though” + past subjunctive “were” indicates unreal state.
“Was” is grammatically possible in informal speech, but C1 academic register favors “were.”
“Is” implies factual predetermination.
