📘 VERY DETAILED EXPLANATIONS

Core Concept: Clause Embedding within Nominal Structures

C2 academic English frequently embeds full clauses inside noun phrases.

This creates:

• High information density
• Structural hierarchy
• Reduced verbal fragmentation
• Formal abstraction

Example transformation:

Less advanced:
Many believe that markets behave rationally.

C2 density:
The assumption that markets behave rationally…

Now let’s break each item down.

1. that ✓

“Assumption” requires a complement clause introduced by “that.”

Structure:
Noun + that-clause

“Which” introduces relative clause, not content clause.
“What” cannot follow a noun directly.

2. to implement ✓

“Failure” + infinitive is fixed structure.

The failure to + verb

Not “failure implement” (missing infinitive marker).
Not gerund here.

3. that ✓

Possibility + that-clause

Content clause explaining the nature of possibility.

“Of” would require gerund: possibility of misinterpreting.

But here full clause required.

4. on ✓

Fixed collocation:

Insistence on + noun/gerund

Not “insistence in” or “for.”

Advanced writing requires collocational precision.

5. that ✓

Premise + that-clause

Academic noun + embedded proposition.

6. of ✓

Erosion of + noun

Fixed nominal pattern.

“Erosion for privacy” incorrect.

7. that ✓

Claim + that-clause

Content clause structure.

8. to ✓

Tendency + to + verb

“Tendency of” would require gerund: tendency of oversimplifying (less common, awkward).

Infinitive is standard C2 structure.

9. that ✓

Recognition that + clause

Not “recognition of bias exists” — grammatically broken.

10. to ✓

Reluctance + to + verb

Fixed academic pattern.

11. of ✓

Reconsideration of + noun phrase

Not “for” or “about” in this nominal structure.

12. that ✓

Expectation that + clause

C2 writing embeds propositions as noun complements.

13. to ✓

Capacity to + verb

Capacity of + noun would shift structure.

14. that ✓

Perception that + clause

Embedded proposition.

15. of ✓

Prioritization of + noun

Standard nominal construction.
