Teacher: 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 (", ").
Teacher: Now, understand the problem? If you are still confused, see the following example:
Paragraph- Sent 1: A Republican bid to keep the government open past Friday includes no new money for the construction of a border wall along the U.S.-Mexico border, according to several congressional aides familiar with ongoing talks.
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.
Question: Who has to be appeased to keep the government open?.
Solution: 1, 2.
Reason: The question is: Who has to be appeased to keep the government open? The phrase "appease Democrats" is mentioned in Sent 2, about accepting offer that is mentioned in Sent 1 to "keep the government open". So, Sent 1 and Sent 2 are the sentences needed to answer this question.

Now, solve this instance: Paragraph- Sent 1: In short, the United States has to help defeat an ideology, not just a group of people, and we must do so under difficult circumstances.
Sent 2: How can the United States and its friends help moderate Muslims combat the extremist ideas?
Sent 3: Recommendation: The U.S. government must define what the message is, what it stands for.
Sent 4: We should offer an example of moral leadership in the world, committed to treat people humanely, abide by the rule of law, and be generous and caring to our neighbors.
Sent 5: America and Muslim friends can agree on respect for human dignity and opportunity.
Sent 6: To Muslim parents, terrorists like Bin Ladin have nothing to offer their children but visions of violence and death.
Sent 7: America and its friends have a crucial advantage-we can offer these parents a vision that might give their children a better future.
Sent 8: If we heed the views of thoughtful leaders in the Arab and Muslim world, a moderate consensus can be found.
Sent 9: That vision of the future should stress life over death: individual educational and economic opportunity.
Sent 10: This vision includes widespread political participation and contempt for indiscriminate violence.
Sent 11: It includes respect for the rule of law, openness in discussing differences, and tolerance for opposing points of view.
Sent 12: Recommendation: Where Muslim governments, even those who are friends, do not respect these principles, the United States must stand for a better future.
Sent 13: One of the lessons of the long Cold War was that short-term gains in cooperating with the most repressive and brutal governments were too often outweighed by long-term setbacks for America's stature and interests.
Sent 14: American foreign policy is part of the message.
Sent 15: America's policy choices have consequences.
Sent 16: Right or wrong, it is simply a fact that American policy regarding the Israeli-Palestinian conflict and American actions in Iraq are dominant staples of popular commentary across the Arab and Muslim world.
Sent 17: That does not mean U.S. choices have been wrong.
Sent 18: It means those choices must be integrated with America's message of opportunity to the Arab and Muslim world. 
Question: should offer an example of moral leadership in the world.
