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 (", ").

[EX Q]: Paragraph- Sent 1: Rivers flowing over gentle slopes move more slowly.
Sent 2: They move much more slowly than a mountain stream.
Sent 3: These slow moving streams create different types of features than mountain streams.
Sent 4: Slow moving water erodes the sides of their channels more than the bottom.
Sent 5: Also, large curves in the stream form.
Sent 6: These curves are called meanders.
Sent 7: Meanders are caused by erosion and deposition.
Sent 8: Remember, faster moving water causes erosion more quickly.
Sent 9: Slower moving water erodes material more slowly.
Sent 10: If water is moving slowly enough, the sediment being carried may settle out.
Sent 11: This settling out, or dropping off, of sediment is deposition.
Sent 12: The curves are called meanders because they slowly wander over the land.
Sent 13: As meanders erode from side to side, they create a floodplain.
Sent 14: This is a broad, flat area on both sides of a river.
Sent 15: Eventually, a meander may become cut off from the rest of the river.
Sent 16: This forms an oxbow lake. 
Question: Do meanders cause oxbow lakes?.
[EX A]: 15, 16.
