📘 EXTREMELY DETAILED EXPLANATIONS<\/h1>\n
\n

1. Hardly had…<\/h3>\n

\u201cHardly\u201d is a negative adverbial. When placed at the beginning of a sentence, inversion is mandatory<\/strong>. Additionally, because one past event happened immediately before another, the first action must be in the past perfect<\/strong>. Therefore:
Hardly had the committee reached\u2026<\/em><\/p>\n

\n

2. Cleft Structure<\/h3>\n

\u201cIt was not until\u2026\u201d forms a cleft sentence<\/strong> used for emphasis. The clause must be introduced by that<\/strong>, not \u201cwhen\u201d or \u201cwhich.\u201d This is a structural rule, not stylistic preference.<\/p>\n

\n

3. Present Academic Evaluation<\/h3>\n

The semicolon links two independent clauses in present time. The evaluation is ongoing \u2192 simple present \u201cwarrant.\u201d Modal or perfect forms distort time reference.<\/p>\n

\n

4. Conditional Inversion<\/h3>\n

\u201cWere the hypothesis tested\u2026\u201d is a formal inversion equivalent to \u201cIf the hypothesis were tested.\u201d

\n

5. Fixed Prepositional Collocation<\/h3>\n

\u201cImpervious\u201d always governs \u201cto.\u201d At C2, lexical control of adjective-preposition pairing is essential.<\/p>\n

\n

6. Future Perfect<\/h3>\n

\u201cBy the time\u201d signals completion before a future moment. Only future perfect expresses this completion nuance.<\/p>\n

\n

7. Not only inversion<\/h3>\n

Negative structure triggers auxiliary inversion. Subject = plural \u2192 \u201cwere.\u201d<\/p>\n

\n

8. Albeit + participle<\/h3>\n

\u201cAs though\u201d expressing non-factual perception \u2192 \u201cwere.\u201d<\/p>\n
