Concept:Arrange the four parts in a logical sequence so that the passage flows naturally from opening to conclusion.
Explanation:Part Q gives the historical evolution of art (cave paintings to modern murals). It fits best as the first part after sentence 1.
Part P explains that art communicates emotions beyond words. This logically follows the historical context.
Part R states that artists express views on culture, politics, and identity. It builds on the emotional function by adding specific expressions.
Part S says art also raises awareness on social issues. It is a natural extension of R and leads into the concluding sentence 6.
Other orders break the flow. Option 3 (PRQS) puts the general function before historical context, which is less natural. Option 2 (QRPS) places specifics before the general emotion. Option 4 (RSPQ) disrupts chronology.
Answer:Option A (QPRS)
