Sentence Arrangement (PQRS) — Arrange the fragments to form a coherent sentence about a midnight ‘‘hue and cry’’ (R, Q, P, S provided) and justify the correct sequence with linking clues.

Given data

• Fragments: R, Q, P, S.
• R: ‘‘heard the hue and cry at midnight’’
• Q: ‘‘he was nervous and’’
• P: ‘‘did not know’’
• S: ‘‘what to do’’

Concept/Approach
Identify a logical narrative: first the event is heard (R), then the subject’s emotional state (Q), then the consequence (P + S) forming the clause ‘‘did not know what to do’’.

Step-by-step construction
R → Q: ‘‘(He) heard the hue and cry at midnight; he was nervous and...’’Q → P: continues the effect: ‘‘he was nervous and did not know...’’P → S: completes the object clause: ‘‘did not know what to do.’’Final sentence: ‘‘(He) heard the hue and cry at midnight; he was nervous and did not know what to do.’’

Why other orders fail
Starting with P or S breaks the cause–effect flow and leaves pronoun reference unclear. RQPS keeps chronology clear.
