PQRS
Explanation
Active Syntax and Structural Flow: To form a grammatically accurate sentence, the components must be organized according to standard syntax order, which follows a Subject + Verb + Object + Modifier template.
Step 1 (Identify Subject): Part P ("the students") acts as the complete plural noun phrase that functions as the main subject of the sentence.
Step 2 (Identify Verb and Object): Part Q ("organized a campaign") contains the past-tense transitive verb "organized" along with its direct object "a campaign." Placing this directly after the subject gives us the core sentence meaning: "The students organized a campaign..."
Step 3 (Identify Prepositional Modifier): Part R ("on plastic pollution") works as an essential prepositional phrase that modifies the noun "campaign," clearly identifying the specific topic or cause of their initiative.
Step 4 (Identify Adverbial Modifier): Part S ("last week at school") acts as a compound adverbial modifier specifying both the time frame ("last week") and the physical location ("at school") where the entire action took place. This naturally anchors the end of the statement.
Combining these parts seamlessly in alphabetical order yields a complete and logical sentence: "The students organized a campaign on plastic pollution last week at school." This aligns perfectly with the sequence PQRS.
