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: The law was written at a time when public housing complexes were under assault by drug-dealing gangs and politicians were pressured to take action.
Sent 2: Families can be removed for drug use by one member, whether the drug activity is in the home or somewhere else.
Sent 3: Under the Department of Housing and Urban Development' enforcement program, tenants may not avoid eviction simply by claiming ignorance of the crime or an inability to stop it.
Sent 4: Carlos Sanchez, executive director of the Grand Rapids Housing Commission, believes the law can be effective if it's applied with discretion.
Sent 5: The commission administers about 3,500 public housing units in the Grand Rapids area, including Creston Plaza.
Sent 6: "I think if it's done with caution, it's a tool that we desperately needed in our developments," Sanchez said.
Sent 7: Sanchez said Grand Rapids doesn't have the large-scale drug problems larger cities do -- and he wants to keep it that way.
Sent 8: "We've done the best we can to keep it from being so drug-infested it becomes a war zone.
Sent 9: Once the development is taken over, it's very difficult to take them back."Sent 10: Sanchez said the commission relies on police reports in deciding evictions, which he estimated at one or two a year.
Sent 11: Among those cases, according to Leslie Curry, litigation director of Western Michigan Legal Services, was that of a mother evicted from public housing about a year ago with several young children.
Sent 12: She was removed because her 17-year-old son was arrested selling drugs outside the apartment, Curry said.
Sent 13: That left her with the hardship of seeking a place she could afford for herself and her children, without the certainty she afford the rent.
Sent 14: "She didn't know about it," Curry said of the drug deal.
Sent 15: "In Grand Rapids, subsidized housing is critical to people's ability to maintain basic security in their lives.".
