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: I wanted him to tell me more, but he babbled, begging me to forgive him, to understand.
Sent 2: I did not listen.
Sent 3: I took the capturador, a matte black Tiempo Capturado, from his grip and studied it, not really thinking about it or Malaquez or Tasha.
Sent 4: I think I was wondering what it meant to say that a thing was art, so we accepted it as art.
Sent 5: Or perhaps I was thinking about the things that humanity made that would outlive our species.
Sent 6: But I was probably only looking at my reflection in the capturador's lens.
Sent 7: Had he said then that I should use it on myself, I might have.
Sent 8: That moment passed.
Sent 9: I looked at Malaquez.
Sent 10: His eyes opened wider while we watched each other.
Sent 11: His lips contorted as if they had lost their ability to shape sound.
Sent 12: I turned to touch the cube that was Tasha's crypt.
Sent 13: She smiled in trust or pleasure or pride, an erotic Mona Lisa who would smile forever, and I could never know why.
Sent 14: The controls of the capturador were more complex than those of a kitchen model, but I recognized the unstop tab.
Sent 15: I could free Tasha.
Sent 16: If I did, one of three things would happen.
Sent 17: Most likely: she would be meat --there is a reason why stopboxes are most often used in kitchens.
Sent 18: Less likely: she would live the rest of her days with a mind as free of worry as a slug's.
Sent 19: And the tiniest chance of all: she would blink as if I had just materialized in Emil's bedroom, and then she would laugh and tell me that she was going to be immortal.
Sent 20: As I put my hand on the impervious surface of Tasha's stopbox, I heard Malaquez run for the door. 
Question: What did Malaquez do after the protagonist looked at him?.
Output:
9, 10, 11.
