Concept:
Sentence rearrangement requires finding structural links such as Subject + Verb + Object, matching prepositional phrases, and building a continuous, logical thought process from start to finish.
Step-by-Step Structural Linkage:
• Finding the Subject: Look at the fragments to find an appropriate opening noun phrase that can act as the main subject. Fragment
Q (``the police force'') is a proper noun phrase that fits perfectly as a sentence opener.
• Connecting the Subject to its Verb: A subject requires an associated verb phrase. Looking closely at fragment
R (``is a vital force''), it begins with the singular verb ``is'', which perfectly matches our singular subject in
Q. This establishes our first rock-solid structural link:
Q $\rightarrow$ R (``the police force is a vital force...'').
• Linking to a Prepositional Purpose: A vital force needs to perform its function somewhere. Fragment
P (``in maintaining'') provides an ideal prepositional link describing the area of action. This extends our chain:
Q $\rightarrow$ R $\rightarrow$ P (``the police force is a vital force in maintaining...'').
• Completing the Object: The gerund ``maintaining'' is a transitive action that requires a direct object to explain exactly *what* is being maintained. Fragment
S (``law and order'') acts as that complete direct object phrase. This completes our sentence layout:
Q $\rightarrow$ R $\rightarrow$ P $\rightarrow$ S.
Reviewing the full arranged sentence:
``The police force (Q) is a vital force (R) in maintaining (P) law and order (S).''
This reads smoothly, follows standard syntax rules, and delivers a completely clear and coherent meaning.
Analysis of Options:
• Option (A) [QRSP]: "...is a vital force law and order..." is a broken grammatical link between R and S.
• Option (B) [QRPS]: This flows perfectly according to our step-by-step structural analysis.
• Option (C) [SRQP]: Starting with "Law and order is a vital force the police force..." creates structural chaos.
• Option (D) [QSPR]: "The police force law and order..." lacks a connecting verb between the two independent noun phrases.
