I know it’s quite long but anyone willing to help? :( the passage is down below plus the questions are in the comments section (some of the passage is in the comments section because not all could fit in here)

Miss Anstruther, whose life had been cut in two on the night of 10 May, so that she now felt herself a ghost, without attachments or habitation, neither of which she any longer desired, sat alone in the bed-sitting-room she had taken, a small room, littered with the broken, useless objects she had salvaged from the ruin round the
corner. It was one of the many burnt-out ruins of that wild night when explosives and incendiaries had rained on London and the water had run short: it was now a gaunt and roofless tomb, a pile of rubble and smashed beams. Miss Anstruther had for the first few days climbed up to what had been her flat, swarming up broken girders, searching and scrabbling, but not finding what she sought, only here a pot,
there a pan. Her marmalade for May had been there; the demolition men did not care for marmalade. She did not know what else went into those bulging dungaree pockets, and did not really care, for she knew it would not be the thing she sought, for which even demolition men would have no use; the flames, had taken them like a ravaging mouse or an idiot child. They were not among the massed debris on the
basement floor either, where piles of soaked and blackened fragments had fallen through four floors to lie in indistinguishable anonymity together.
