Concept:The parts of a sentence must be arranged in a logical order to form a coherent paragraph.
Explanation:First, look for the sentence that introduces the scene. Sentence P describes Philip looking out of a stone window. This is the natural starting point.
Next, sentence Q explains that the window had no glass. This detail follows logically from P.
Then, sentence R gives more information about the thick wall and how Philip could sit on the window-sill. This adds to the description.
Finally, sentence S describes Philip’s action of hanging and sliding forward to look down. This completes the narrative.
Thus, the correct sequence is P, Q, R, S.
Answer:Option A: PQRS
