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 (", ").

Sent 2: The Taliban have kidnapped him.
Sent 3: If the truck turns right, he knows he's being sold to another militant group.

Sent 10: We will have to walk for several hours up the hillside to one village, and we have to sneak a little bit.
Sent 11: Omar is very particular about I should cover my face.

Sent 14: We have to wait there, because they're going to have a meeting.
