PQRS Sentence Reconstruction — Choose the sequence that best completes the reflective remark (Then … it struck me … of course … how eminently … suitable it was) with logical connectors.

Given data

• P: ‘‘it struck me’’
• Q: ‘‘of course’’
• R: ‘‘suitable it was’’
• S: ‘‘how eminently’’

Concept/Approach
The phrase ‘‘Then it struck me’’ naturally starts (P). An interjection ‘‘of course’’ (Q) fits as a parenthetical after the realization. The intensifier ‘‘how eminently’’ (S) must precede the complement ‘‘suitable it was’’ (R) to read smoothly: ‘‘how eminently suitable it was.’’

Step-by-step construction
Start with P: ‘‘Then it struck me...’’Insert Q for emphasis: ‘‘...of course...’’Use S + R to form the adjective phrase: ‘‘...how eminently suitable it was.’’Final sentence: ‘‘Then it struck me, of course, how eminently suitable it was.’’

Why alternatives are wrong
Placing R before S (e.g., RS) breaks the idiomatic order; starting with Q/S deprives the sentence of a subject–verb anchor.
