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: GOP leaders submitted the new offer Tuesday afternoon in an effort to appease Democrats, whose votes are needed to avert a shutdown of federal agencies, several House and Senate aides said.
Sent 3: However, Republicans also insisted on increases in border security and defense spending, including money to repair existing fencing and new surveillance technology to patrol the nearly 2,000-mile border.
Sent 4: Democrats have indicated that they would support such appropriations so long as no money goes toward an actual wall.

Q: 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.
