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: The 19-year-old is currently playing for Spain at the World Under-20 Championships in Colombia and has signed a four-year deal with last season's Premier League runners-up.
Sent 3: The deal is worth $7 million and includes a buy back clause, set at $14 million after the first year and $21 million after the second.
Sent 4: Romeu started his career at Barcelona's city rivals Espanyol before joining the Camp Nou academy in 2004.
Sent 5: The midfielder, who can also play in central defence, made his debut for Barcelona in last season's Spanish Supercup match with Seville and got his first taste of league action against Deportivo in May 2010.
Sent 6: He has played 90 minutes in both of Spain's games at the World Under-20 Championships, when they beat Costa Rica and Ecuador.
Sent 7: Chelsea official web site confirmed the signing and said Romeu is "renowned for his strength and his expansive passing ability."Sent 8: Another player leaving Barcelona is Jeffren Suarez after he agreed to join Sporting Lisbon.
Sent 9: The Portuguese outfit have paid $5 million for the 23-year-old which, like the Romeu deal, includes a buy back option.
Sent 10: Jeffren joined Barca from Tenerife in 2004 and made his debut for the Catalan club in the 2006-07 season.
Question: Who made his debut in 2010?.
[A]: 1, 5.

[Q]: Paragraph- Sent 1: (CNN) -- Guatemala's government has declared a state of siege and sent hundreds of troops to a northern province where officials say a Mexican drug gang is overtaking towns and threatening residents.
Sent 2: President Alvaro Colom announced the 30-day emergency rule in Alta Verapaz on Sunday.
Sent 3: The rule allows the military to order anyone suspected of conspiring against the government to be arrested and imprisoned without a warrant, the state-run AGN news agency said.
Sent 4: "Starting today, combined forces will retake the streets of Alta Verapaz," a government statement released Sunday morning said.
Sent 5: Government data shows cells of the drug gang known as Los Zetas are in the area to protect drug trafficking paths between Honduras and Mexico, "intimidating the population with their heavy weapons and threatening farmers to give up their land for criminal activities," AGN reported.
Sent 6: The state of siege also allows the government to place greater restrictions on public gatherings, travel visas and gun licenses, among other things, according to AGN.
Sent 7: "The population should be calm.
Sent 8: What we are doing is not intended to persecute honest, working people," Interior Minister Carlos Menocal told reporters.
Sent 9: Menocal said operations in the coming days would aim to boost regional security, regain control of territory, identify criminal gangs and capture their members.
Sent 10: In an interview with CNN en Espanol last month, Menocal said his country needed more help from the United States to combat cartels, which were increasingly carving out new drug transport paths.
Sent 11: "In the end, the large majority of drugs travel through Central America, and the assignment of resources or the financial support of the United States government is not the same as Colombia and Mexico receive," he said.
Sent 12: Menocal said clashes between authorities and Los Zetas had notably increased.
Question: A state of seige declaration lasts how many days?.
[A]: 1, 2.

[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: Before a diver dives after a diver board or before a leaf falls from a branch and remains hanging, there is what type of energy?.
[A]:
1, 2, 11, 12.
