🧠 C2 Compression & Density Logic
🔑 Core C2 Principle
At C2, participle and absolute structures are used to:
• remove repetition
• embed causality
• shift focus from actors to processes
• compress time, cause, and evaluation
The exam checks whether you can replace whole clauses with controlled grammar.
1. Conducted

which was conducted over a decade → conducted over a decade
The study did not conduct; it was conducted.
2. Taking

Taking all variables into account = while they were considering…
3. analyzed

4. Having been
