Very Detailed Explanations
1. Proposes that the framework be adopted
Verbs such as propose, recommend, insist, demand, suggest trigger the mandative subjunctive in formal English.
Correct structure:
that + subject + base verb
“Be adopted” uses the base form.
Option D (“should”) is grammatically possible in British English but stylistically weaker in high-level academic prose.
2. Had the premise been examined…
This is an inverted third conditional.
Full form:
If the initial premise had been examined…
“Been examined” is past perfect passive.
Past unreal condition → past unreal consequence.
Option A is grammatically impossible because “had” must be followed by a past participle.
3. Were the data to contradict…
This is a formal hypothetical referring to a possible future scenario.
Structure:
Were + subject + to + base verb
This expresses remote possibility in academic speculation.
“Were the data be” is incorrect because “were” cannot be followed directly by “be” in this structure.
4. It is imperative that no participant be excluded
Adjectives triggering subjunctive:
imperative
essential
crucial
vital
necessary
Even though “participant” is singular, the verb remains base form.
Subjunctive ignores normal subject–verb agreement.
5. But for the intervention…
“But for” = If it had not been for.
Thus third conditional:
would have been terminated
This indicates a past unreal outcome.
6. If the assumptions had been framed…
Past unreal cause
Present result (“would be less severe today”)
This is a mixed conditional.
Past action influences present consequence.
Option A (“were framed”) would imply present hypothetical, not past.
7. Recommends that each variable be verified
Again, mandative subjunctive.
Even with singular subject “each variable,” verb remains base form.
8. Were it not for…
Fixed structure.
Equivalent to:
If it were not for…
Always followed by “for.”
9. As though they were universally accepted
Unreal present comparison.
“As though” + past simple expresses imagined present state.
Using “are” would imply factual acceptance.
10. Had the attempts succeeded…
Inverted third conditional.
Past unreal condition
Past unreal result
Thus:
would have diminished
11. It is essential that… be acknowledged
Institutional subjunctive again.
Academic writing strongly prefers base form after such adjectives.
12. If the authors exercised greater caution…
This is a second conditional referring to present hypothetical.
Present unreal condition
Present result (“might carry more weight now”)
“Had exercised” would shift to past cause with present consequence — but context implies ongoing issue, not completed past action.
13. Were the assumption to be invalid…
Formal future hypothetical.
Structure:
Were + subject + to be + complement
Indicates possibility, not current reality.
14. Had it not been for…
Classic inverted third conditional.
Past unreal condition
Past unreal result
Thus:
would not have been possible
15. As if it were immune…
Unreal present comparison.
“Were” signals distance from factual assertion.
Using “is” would imply certainty.
