SI : Wordsworth knew the behaviour of owls in the night better than most of us know the ways of black birds in day time. S6: His great poetry owes much to the night. P : Out of school there were no restrictions on the hours he kept. Q : No poet ever had happier schooldays. R : He would skate by the light of the stars, snare woodcocks at dead of night, watch the sunrise after a long ramble. S : Throughout life he was an inveterate walker by night. The proper sequence should be
- AQ P R S
- BP S Q R
- CQ R P S
- DS Q P R
Explanation
S1 praises Wordsworth's knowledge of night life. Q opens with his happy schooldays, P notes the lack of restrictions on his hours, R gives the night-time examples (skating by starlight, snaring woodcocks), and S generalizes to his lifelong night walking — leading into S6's tribute to his night poetry. The order Q P R S (A) is the only coherent chain. Hence the answer is A.
