Concept:The question asks to rearrange jumbled parts (P, Q, R, S) of a sentence into a logical order using grammatical and contextual links.
Explanation:Part Q ("an epigram is a brief and") begins the sentence because it introduces the subject and starts the definition.
Part R ("pointed saying that frequently") follows Q as it adds more detail about the epigram.
Part P ("introduces antithetical ideas") comes next, explaining what the saying frequently does.
Part S ("that cause one to think afresh") concludes the sentence by describing the effect of those antithetical ideas.
The correct sequence is Q, R, P, S, forming the complete sentence: "An epigram is a brief and pointed saying that frequently introduces antithetical ideas that cause one to think afresh."
