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: Consider Input: Paragraph- Sent 1: This apartment, the best in Fort Laramie, was that usually occupied by the legitimate bourgeois, Papin; in whose absence the command devolved upon Bordeaux.
Sent 2: The latter, a stout, bluff little fellow, much inflated by a sense of his new authority, began to roar for buffalo robes.
Sent 3: These being brought and spread upon the floor formed our beds; much better ones than we had of late been accustomed to.
Sent 4: Our arrangements made, we stepped out to the balcony to take a more leisurely survey of the long looked-for haven at which we had arrived at last.
Sent 5: Beneath us was the square area surrounded by little rooms, or rather cells, which opened upon it.
Sent 6: These were devoted to various purposes, but served chiefly for the accommodation of the men employed at the fort, or of the equally numerous squaws, whom they were allowed to maintain in it.
Sent 7: Opposite to us rose the blockhouse above the gateway; it was adorned with a figure which even now haunts my memory; a horse at full speed, daubed upon the boards with red paint, and exhibiting a degree of skill which might rival that displayed by the Indians in executing similar designs upon their robes and lodges.
Sent 8: A busy scene was enacting in the area.
Sent 9: The wagons of Vaskiss, an old trader, were about to set out for a remote post in the mountains, and the Canadians were going through their preparations with all possible bustle, while here and there an Indian stood looking on with imperturbable gravity.
Question: How did Bordeaux feel about his new authority?.

Output: 1, 2.

Input: Consider Input: Paragraph- Sent 1: What happens when two forces act in opposite directions?
Sent 2: Net force is the difference between the two forces.
Sent 3: In other words, one force is subtracted from the other.
Sent 4: Think back to the book example.
Sent 5: One force was opposite the other.
Sent 6: The forces were equal in each direction.
Sent 7: In this case, the net force is zero.
Sent 8: Because the forces on the book are balanced, the book doesn't move.
Sent 9: It does not fall to the ground.
Sent 10: The table is not breaking.
Sent 11: The book is not falling to the ground.
Sent 12: Both are evidence that the force are balanced.
Sent 13: Situations like these are common.
Sent 14: Can you think of objects sitting on shelves or tables?
Sent 15: These are all examples of balanced forces.
Sent 16: Thanks to balanced forces objects stay where you put them.
Question: What is the net force when the forces are equal in direction.

Output: 6, 7.

Input: Consider Input: Paragraph- Sent 1: Gravitational Potential Energy is affected by position.
Sent 2: Like the leaves on trees, anything that is raised up has the potential to fall.
Sent 3: It has potential energy.
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.
Sent 8: Like the skateboarder, the higher the ramp, the faster he will be going when he reaches the bottom.
Sent 9: Like all energy, gravitational potential energy has the ability to do work.
Sent 10: In this case, weight has the potential to deliver a force.
Sent 11: More important for us is that it has the ability to cause change.
Sent 12: What kind of change you may ask?
Sent 13: Gravitational potential energy has the ability to cause motion.
Question: What is the most important change gravitational potential energy can have.
Output: 11, 13.
