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 (", ").

Q: Paragraph- Sent 1: What happens when a diver jumps off the diving board?
Sent 2: His gravitational potential energy changes to kinetic energy as he falls.
Sent 3: In other words, he falls faster and faster until reaching the water.
Sent 4: However, he can always regain his potential energy.
Sent 5: All he must do is get out of the water and climb back up.
Sent 6: This requires an input of kinetic energy.
Sent 7: These changes in energy are examples of energy conversion.
Sent 8: Energy can be converted from one form to another.
Sent 9: It can also be transferred from one object to another.
Sent 10: Think back to the leaf example.
Sent 11: The leaf was hanging from a branch.
Sent 12: At this time, it had gravitational potential energy.
Sent 13: As it came loose from the branch, gravity pulled it toward the ground.
Sent 14: The leaf started to fall, or move, toward the ground.
Sent 15: Its potential energy was changed into motion.
Sent 16: As it landed on the ground, it stopped moving.
Sent 17: As it lays on the ground, it has no potential to move.
Sent 18: If it does move it is because something else transferred energy to it.
Question: What are examples of energy conversion?.

A: 2, 4, 5, 6, 7.

Q: Paragraph- Sent 1: ROME, Italy (CNN) -- A U.N. report says hunger is on the rise globally and blames higher food prices.
Sent 2: Populations within conflict zones such as the Democratic Republic of Congo are particularly vulnerable.
Sent 3: The Food and Agriculture Organization has issued preliminary estimates classifying 963 million people as undernourished -- an increase of 40 million people over the past year.
Sent 4: "One out of seven people -- about 15 percent -- suffer chronically of not having enough to eat," said Mark Smulders, an FAO economist.
Sent 5: The hunger report -- titled "The State of Food Insecurity in the World 2008" -- said the world's financial and economic problems could throw more people into poverty.
Sent 6: The number of hungry had been increasing over the years before the rise in food prices, with warfare and political instability continuing to be among the factors causing poverty.
Sent 7: The preliminary estimates lack a firm country breakdown, but last year's figures are an accurate measure of where the problems are.
Sent 8: About 907 out of 923 million undernourished people in 2007, or 65 percent of the hungry, live in India, China, the war-wracked Democratic Republic of Congo, Bangladesh, Indonesia, Pakistan and Ethiopia.
Sent 9: Smulders said about 27 percent of the world's hungry live in India and 15 percent in China.
Sent 10: The other countries each represent 4 to 5 percent of the world's total.
Sent 11: There has been progress in fighting hunger in the Asian nations of Thailand and Vietnam, and in the sub-Saharan African nations of Ghana, Republic of Congo, Nigeria, Mozambique and Malawi, the report said.
Question: What are some of the reasons for global hunger?.

A: 1, 5, 6.

Q: Paragraph- Sent 1: Romulus, Michigan (CNN) -- A Nigerian man is "talking a lot" to the FBI, said a senior U.S. official, after what the United States believes was an attempted terrorist attack on an inbound international flight.
Sent 2: The initial impression is that the suspect was acting alone and did not have any formal connections to organized terrorist groups, said the senior official who is familiar with the investigation.
Sent 3: The suspect, identified by a U.S. government official as 23-year-old Umar Farouk Abdulmutallab, ignited a small explosive device Friday, shortly before a Northwest flight from Amsterdam, Netherlands, made its landing in Detroit, Michigan.
Sent 4: With the aid of the cabin crew, another passenger quickly helped subdue and isolate Abdulmutallab, passenger Syed Jafry told CNN.
Sent 5: Abdulmutallab, was placed in custody and is being treated for second- and third-degree burns on his thighs, according to federal law enforcement and airline security sources.
Sent 6: The sources told CNN that the suspect flew into Schiphol Airport in Amsterdam on a KLM flight from Lagos, Nigeria, and is not believed to be on any "no fly" list, although his name does appear in a U.S. database of people with suspect connections.
Sent 7: He did not undergo secondary security screening in Amsterdam, an administration official said.
Sent 8: The administration official said there was no evidence that Abdulmutallab was a hard-core, trained member of al Qaeda.
Sent 9: Abdulmutallab, a Nigerian national, claimed to have extremist ties and said the explosive device "was acquired in Yemen along with instructions as to when it should be used," a federal security bulletin obtained by CNN said.
Sent 10: The remains of the device used are being sent to an FBI explosives lab in Quantico, Virginia, for analysis, security sources said.
Sent 11: U.S. President Barack Obama, who is spending the holidays in his home state of Hawaii, was briefed on the incident during a secure phone call with aides, and instructed in a subsequent discussion with security advisers "that all appropriate measures be taken to increase security for air travel," White House spokesman Bill Burton told CNN.
Sent 12: The president made no changes to his schedule, Burton said.
Question: A small explosive device caused what type of injuries to the suspect?.
