QUESTION 3 Read the following passage carefully and answer the questions that follow: [25] Ann turned into the wing of the house which was quite deserted and silent. At the end of it, a shut door confronted her. She opened it softly. It was dark within, but enough light entered from the corridor to show her the high bookcases ranged against the walls, the position of the furniture, and some dark, heavy curtains at the end. She was the first, then, to come to the meeting. She closed the door behind her and moved slowly and cautiously forward with her hands outstretched, until she felt the curtains yield. She passed in between them into the recess of a great bow-window, opening onto the park; and a sound, a strange creaking sound, brought her heart into her mouth. 2 Someone was already in the room there. Someone had been quietly watching as she came in from the lighted corridor. The sound grew louder. Ann peered between the curtains, holding them apart with shaking hands, and through that chink from behind her, a vague twilight flowed into the room. In the far corner, near the door, high up on a tall bookcase, something was clinging something was climbing down. Whatever it was that had been hiding behind the ornamental top of the heavy mahogany bookcase was now using shelves like the rung of a ladder. Ann was seized with panic. A sob broke from her throat. She ran for the door, but she was too late. A black figure dropped from the bookcase onto the ground and, as Ann reached her hands out to the door, a scarf was whipped about her mouth, stifling her cry. She was jerked back into the room, but her fingers had touched the light switch by the door, and as she stumbled and fell, the room lit up. Her assailant fell upon her, driving the breath out of her lungs, and knotting the scarf tightly at the back of her head. Ann tried to lift herself, and recognized with a gasp of amazement that the assailant who pinned her down by the weight of her body and the thrust of her knees was Francine Rollard. Her panic gave place to anger and burning humiliation. She fought with the strength of her supple body, but the scarf about her mouth stifled and weakened her, and with growing dismay, she understood that she was no match for the hardy peasant girl. She was the taller of the two, but her weight did not avail her; she was like a child matched with a wild cat. Francine s hands were made of steel. She snatched Ann s arms behind her back and bound her wrists, as she lay face down, her bosom labouring, her heart racing so that she felt it might burst. Then, as Ann gave up the contest, she turned and tied her by the ankles. (a) Give the meanings of the following words as used in the passage. One word answers or short phrases will be accepted.
