Logic, Counterfactuals & Argument Grammar (IELTS, TOEFL, YDS) -C2 Grammar Test
This C2 grammar test focuses on how advanced English encodes:

• layered contrast
• causal architecture
• analytical evaluation
• argumentative nuance
Choose the correct answer.

#3. But for the unexpected intervention, the negotiations ___ altogether.
#4. While the model accounts for surface-level patterns, it falls short ___ deeper systemic dynamics.
#5. Had the study incorporated longitudinal data, its conclusions ___ considerably more robust.
#6. Even if the criticism were justified, it ___ invalidate the broader theoretical framework.
#7. The argument is persuasive insofar ___ it addresses immediate concerns.
#8. The policy was revised, ___ it failed to account for regional disparities.
#9. Had the risks been more carefully assessed, the crisis ___ such proportions.
#10. Granted the inherent uncertainty of the data, the findings ___ be treated with caution.
#11. The proposal is defensible only to the extent ___ its implementation remains provisional.
#12. The study claims neutrality; ___, its underlying assumptions reveal a clear ideological orientation.
#13. Had the variables been controlled differently, the outcome ___ an alternative interpretation.
#14. The explanation, however elegant, cannot ___ the full complexity of the phenomenon.

🧠 C2 Logic & Argument Grammar
🔑 Core C2 Principle
At C2, grammar becomes argument structure.
You are not choosing tenses.
You are choosing:
• what is conceded
• what is undermined
• what is conditional
• what is limited
• what logically follows
1. would have been
Unreal past condition → unreal past result.
Used to re-evaluate past analytical foundations.
2. would not have overcome
Concession + unreal past.
Even if funding had existed, limitations would still have existed.
This structure preserves critical distance.
3. would have collapsed
“But for…” = if it had not been for…
Always triggers third conditional meaning.
4. of explaining
fall short of + gerund
Academic critique structure.
5. would have been
Past methodological gap → past analytical weakness.
6. would not
Even if + were = unreal present concession.
Used to limit the force of criticism.
7. as
insofar as = to the extent that
C2 connector expressing conditional validity.
8. on the grounds that
Formal causal justification.
The policy was revised because it failed.
9. would not have reached
Counterfactual past + evaluative outcome.
10. should
“Should be treated with caution” expresses methodological recommendation, not possibility.
11. that
extent that = fixed analytical structure.
12. nevertheless
Introduces direct contradiction between claim and analysis.
13. would have permitted
Past unreal condition → alternative analytical possibility.
14. account for
account for = explain.
account / account of are incorrect collocations.
15. despite
Concessive contrast between influence and criticism.
🧠 What this test really trains
This grammar lets you:
• dismantle weak arguments
• concede without surrendering
• layer logic
• encode critique
• write like a reviewer, not a student
This is academic reasoning grammar.
