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 (", ").
One 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 is here: 1, 2.
Explanation: 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: Paragraph- Sent 1: Bin Ladin began delivering diatribes against the United States before he left Saudi Arabia.
Sent 2: He continued to do so after he arrived in Sudan.
Sent 3: In early 1992, the al Qaeda leadership issued a fatwa calling for jihad against the Western "occupation" of Islamic lands.
Sent 4: Specifically singling out U.S. forces for attack, the language resembled that which would appear in Bin Ladin's public fatwa in August 1996.
Sent 5: In ensuing weeks, Bin Ladin delivered an often-repeated lecture on the need to cut off "the head of the snake."Sent 6: By this time, Bin Ladin was well-known and a senior figure among Islamist extremists, especially those in Egypt, the Arabian Peninsula, and the Afghanistan-Pakistan border region.
Sent 7: Still, he was just one among many diverse terrorist barons.
Sent 8: Some of Bin Ladin's close comrades were more peers than subordinates.
Sent 9: For example, Usama Asmurai, also known as Wali Khan, worked with Bin Ladin in the early 1980s and helped him in the Philippines and in Tajikistan.
Sent 10: The Egyptian spiritual guide based in New Jersey, the Blind Sheikh, whom Bin Ladin admired, was also in the network.
Sent 11: Among sympathetic peers in Afghanistan were a few of the warlords still fighting for power and Abu Zubaydah, who helped operate a popular terrorist training camp near the border with Pakistan.
Sent 12: There were also rootless but experienced operatives, such as Ramzi Yousef and Khalid Sheikh Mohammed, who-though not necessarily formal members of someone else's organization-were traveling around the world and joining in projects that were supported by or linked to Bin Ladin, the Blind Sheikh, or their associates.
Sent 13: In now analyzing the terrorist programs carried out by members of this network, it would be misleading to apply the label "al Qaeda operations" too often in these early years.
Sent 14: Yet it would also be misleading to ignore the significance of these connections.
Sent 15: And in this network, Bin Ladin's agenda stood out.
Sent 16: While his allied Islamist groups were focused on local battles, such as those in Egypt, Algeria, Bosnia, or Chechnya, Bin Ladin concentrated on attacking the "far enemy"-the United States.
Sent 17: After U.S. troops deployed to Somalia in late 1992, al Qaeda leaders formulated a fatwa demanding their eviction.
Sent 18: In December, bombs exploded at two hotels in Aden where U.S. troops routinely stopped en route to Somalia, killing two, but no Americans.
Question: In the early 90s, which regions were most affected by al Qaeda's agenda?.
Solution:
16.
