Concept:The rearrangement must create a logical flow from the broad idea of books to specific benefits, ending with a conclusion.
Explanation:Sentence 1 states books are a source of knowledge. P directly continues this by saying books let us travel across time and space. R then adds that stories fuel our imagination. Q explains that we learn about different cultures and civilizations. S broadens the scope by mentioning books cover every field from science to art. This leads logically to Sentence 6, which concludes that reading must be encouraged.
The correct sequence is P, then R, then Q, then S. This order moves from the general idea of travel, to imagination, to cultural learning, and finally to the wide range of topics.
Answer:Option C (PRQS) is the correct answer.
