✅ Detailed Explanations (All Answers Explained Together)
Question 1 — B ✓
Structure: Third conditional (past condition) + present result → mixed conditional
Form: If + past perfect → would + base verb
Meaning Logic:
The decision not taken last year affects present expansion status.
Why A fails:
Simple past creates second conditional (present unreal), not past decision.
Why C fails:
Modal verbs never appear in if-clauses of conditionals.
Academic Note:
Common in economic policy analysis essays (IELTS Writing Task 2).
Question 2 — A ✓
Structure: “As though” + past simple → unreal present implication.
Meaning Logic:
She was not involved; speaker implies false authority.
Why C fails:
Past perfect would imply unreal past before another past point — timeline mismatch.
Rhetorical Effect:
Subtle skepticism — frequent in academic critique.
Question 3 — C ✓
Structure: Inverted third conditional → present progressive result.
Logic:
Incorrect interpretation (past) influences ongoing strategy.
Why B fails:
Would have adopted = completed past.
Question 4 — B ✓
Structure: Present unreal condition → past result.
Logic:
He lacks discipline generally; that explains past failure.
IELTS Trap:
Learners wrongly choose “would win.”
Question 5 — A ✓
Structure: Past report condition → present criticism.
Meaning:
Transparency in the past affects current public response.
Question 6 — B ✓
Structure: “As if” + past simple → unreal past inference from present evidence.
Logic:
Speaker infers prior knowledge before publication.
Why C fails:
Past perfect overemphasizes sequence; no reference point needed.
Question 7 — A ✓
Structure: Past modernization → present economic condition.
Why B fails:
Would have been refers to past strength, not now.
Question 8 — C ✓

Logic:
Evidence was insufficient; affects past jury decision.
Question 10 — A ✓
Structure: Present condition (having fewer duties) → completed present result.
Why B fails:
“Had had” implies past possession before another past event — unnecessary complexity.
Subtle Trap:
“By now” signals present completion.
Question 11 — B ✓
Structure: Present unreal theory → past experimental result.
Academic Logic:
Scientific validation refers to past trials.
Question 12 — A ✓

Structure: Past unreal understanding → past action.
Classic third conditional.
Question 14 — A ✓
Structure: “As though” + present simple → implied unreal present.

Past simple would imply distance; here authority claim is current.
Question 15 — B ✓

IELTS Writing Parallel:
Policy weakness → past disaster.
