Question

Read the following passage carefully:

"The gallery at Mordaunt Grange was a long, draftswept corridor that seemed to exist only to connect the abandoned chapel with the nursery where the children had long since grown to bitter maturity. Along its eastern wall ran a series of high, narrow lancet windows, each leaded frame choked with decades of grime, through which the gray north-country light filtered like ash. Here, the portraits of the Mordaunt ancestors hung in varying stages of decay; canvas after canvas had buckled under the damp, the paint peeling away in scabs of ochre and lampblack to reveal the rough burlap underneath. It was a space where the house's past did not merely linger, but decayed actively, contaminating the present with its rot. Whenever Clara walked the length of the gallery, she felt the dampness rising from the flagstones not merely as a physical chill, but as a heavy, silent accusation. The floorboards, warped by seasons of rain that had leaked through the rotting eaves, groaned under her light tread, sounding less like timber and more like the dry rattling of old bones. To Clara, the gallery was not a passage between rooms, but a physical suspension of time—a place where the family’s decline was both recorded and enforced by the very stones that bound them."
