Input: Consider Input: Paragraph- Sent 1: Heavy wooden shutters dulled the noise of the boisterous gale outside.
Sent 2: A thick red curtain hung over the door, and a cheery log fire burnt in the stove.
Sent 3: A man and woman sat over it; the man, a tall, repulsive-looking creature, with unkempt hair and matted beard, his age apparently about fifty.
Sent 4: The woman looked seventy or more.
Sent 5: She too had once been tall, but now old age gave her a withered, witch-like appearance, in spite of her great height.
Sent 6: She was dressed in limp, faded garments, with a tattered shawl crossed over her chest, and had a scared, miserable look in her bleared old eyes.
Sent 7: There were a few words of explanation from the man who had come home, and then, in gruff but not unkindly tones, he bade Babette be seated, and told his mother to get some supper speedily.
Sent 8: She spread a coarse cloth on the wooden table, and when all was ready, lifted a large black saucepan from the stove and turned out a smoking, savoury-looking stew.
Sent 9: The youngest son produced a bottle containing the thin acid wine of the country, and another of spirits.
Sent 10: As he set them on the table, Babette noticed that across one of his hands, which were much smaller and whiter than those of his brothers, there ran a dull red scar that looked as if he had had a bad cut there.
Sent 11: Then they all sat down, excepting the old mother, who busied herself in waiting on them.
Question: Who has a scar on his hand? (A) The man sitting in front of the stove (B) The youngest son.

Output: B.

Input: Consider Input: Paragraph- Sent 1: The little party in the cabin, so disastrously begun, finished, under the mellowing influence of wine and woman, in excellent feeling and with some hilarity.
Sent 2: Mamie, in a plush Gainsborough hat and a gown of wine-coloured silk, sat, an apparent queen, among her rude surroundings and companions.
Sent 3: The dusky litter of the cabin set off her radiant trimness: tarry Johnson was a foil to her fair beauty; she glowed in that poor place, fair as a star; until even I, who was not usually of her admirers, caught a spark of admiration; and even the captain, who was in no courtly humour, proposed that the scene should be commemorated by my pencil.
Sent 4: It was the last act of the evening.
Sent 5: Hurriedly as I went about my task, the half-hour had lengthened out to more than three before it was completed: Mamie in full value, the rest of the party figuring in outline only, and the artist himself introduced in a back view, which was pronounced a likeness.
Sent 6: But it was to Mamie that I devoted the best of my attention; and it was with her I made my chief success.
Question: What task took more than three hours to complete? (A) Drawing Mamie (B) Taking the picture (C) Sketching a picture of the scene (D) Drawing the party (E) Cleaning up after the party (F) Drawing the picture.

Output: A, C, D, F.

Sent 2: What do you think matter is used for?

Sent 4: They also need it to carry out the processes of life.
Sent 5: Any non-living matter that living things need is called a nutrient.
Sent 6: Carbon and nitrogen are examples of nutrients.

Sent 8: You can see how in Figure 3.11.
Sent 9: Decomposers release nutrients when they break down dead organisms.
Sent 10: The nutrients are taken up by plants through their roots.
Sent 11: The nutrients pass to primary consumers when they eat the plants.
Sent 12: The nutrients pass to higher level consumers when they eat lower level consumers.
Sent 13: When living things die, the cycle repeats.

A hunter kills the rabbit for food and eats it (B) Living things die and go extinct as a result of interaction with other animals (C) Nutrients pass to primary consumers (D) Nutrients pass through consumers.
