In the following question the 1st and the last part of the sentence/passage are numbered 1 and 6. The rest of the sentence/ passage is split into four parts and named P, Q, R and S.

P - Casterbridge was the complement of the rural life around, not its urban opposite. Q - And in autumn airy spheres of thistledown floated into the same street, lodged upon the shop fronts, blew into drains, and innumerable tawny and yellow leaves skimmed along the pavement, and stole through people's doorways into their passages with a hesitating scratch on the floor, like the skirts of timid visitors.  R- Bees and butterflies in the cornfields at the top of the town, who desired to get to the meads at the bottom, took no circuitous course, but flew straight down High Street without any apparent consciousness that they were traversing strange latitudes. S - Hearing voices, one of which was close at hand, she withdrew her head and glanced from behind the window-curtains. 2 - Mr. Henchard--now habited no longer as a great personage, but as a thriving man of business--was pausing on his way up the middle of the street, and the Scotchman was looking from the window adjoining her own.
