Definition: You are given a paragraph, with numbered sentences, and a question. Write the numbers of the sentences needed to answer the given question. Separate multiple sentence numbers with a comma (", "). E.g. "1, 2" would be the correct response if Sent 1 and Sent 2 are needed to answer the given question (do not include sentences that contain no information that is necessary to answer the question). Sort the sentence numbers in an increasing order (i.e., '1, 2', instead of '2, 1'). Your answer should not contain anything than the sentence numbers separated by a comma (e.g. '1, 2, 3, 4'). The given question requires more than one sentence to answer. So, your answer must contain at least one comma (", ").
Input: Paragraph- Sent 1: Don't think them heartless; they are neither better nor worse than you or I; they get over their professional horrors, and into their proper work; and in them pity, as an _emotion_, ending in itself or at best in tears and a long-drawn breath, lessens, while pity, as a _motive_, is quickened, and gains power and purpose.
Sent 2: It is well for poor human nature that it is so.
Sent 3: The operating-theatre is crowded; much talk and fun, and all the cordiality and stir of youth.
Sent 4: The surgeon with his staff of assistants is there.
Sent 5: In comes Ailie; one look at her quiets and abates the eager students.
Sent 6: That beautiful old woman is too much for them; they sit down, and are dumb, and gaze at her.
Sent 7: These rough boys feel the power of her presence.
Sent 8: She walks in quietly, but without haste; dressed in her mutch, her neckerchief, her white dimity short-gown, her black bombazeen petticoat, showing her white worsted stockings and her carpet shoes.
Sent 9: Behind her was James with Rab.
Sent 10: James sat down in the distance, and took that huge and noble head between his knees.
Sent 11: Rab looked perplexed and dangerous--forever cocking his ear and dropping it as fast.
