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 4: You can see examples of people with gravitational potential energy in 1.5 Figure below.
Sent 5: Gravitational potential energy depends on two things.
Sent 6: It depends on its weight, because a large falling rock can do more damage than a leaf falling from a tree.
Sent 7: It also depends on its height above the ground.
