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 13: As it burns, the chemical energy is changed into light and heat.
Sent 14: Not all chemical energy changes produce light and heat.
Sent 15: Our cars use gasoline as a fuel.
Sent 16: Gasoline contains chemical energy.
Sent 17: When our cars burn gasoline in their engines, it is converted into motion and heat.

Q: Paragraph- Sent 1: It's just this hard when I try to answer the question: Why do older Oklahomans need lawyers?
Sent 2: The answers are important enough that they will be a discussion topic of this year's Senior Day at 9 a.m.
Sent 3: March 25 in the House Chamber at the Capitol.
Sent 4: The following is a preview of some of the answers for review: We can all agree that older Oklahomans need medical care.
Sent 5: But even the best care is worthless if an older patient can't drive to the doctor for ongoing treatment because his or her car has been wrongfully seized in a debt dispute.
Sent 6: Therefore, lawyers are part of the prescription for regular medical care for many of the 600,000 Oklahomans age 60 and older.
Sent 7: Another example: if a doctor treats an elderly patient for a lung ailment, the doctor's treatment will be undone and he will see the patient again and again, if the patient is sent home to an unheated apartment.
Sent 8: Lawyers know how to make landlords heat apartments so the medical treatment can stick.
Sent 9: (By the way, a May 16, 2001, article in The New York Times reports on a program at Boston Medical Center providing a walk-in legal clinic in the hospital to help fight their patients' legal and administrative battles.) We also can agree that older Oklahomans - like all citizens - have rights to control their health care until they become incapacitated or these rights are transferred to another by legal document or process.
Sent 10: "Old" is not a legal classification that results in automatic loss of these rights.
Sent 11: Moreover, having an old parent does not automatically confer on children the right to make the parents' health care choices.
Sent 12: It follows that an important role lawyers provide for aging Oklahomans is not only to create rights - transferring documents such as durable powers of attorney and guardianship orders, but also to monitor their use.
Sent 13: In family situations, for example, lawyers must ensure that powers of attorney and guardianships are used to serve only the person transferring or losing rights.
Sent 14: They are not to be used to help a family "manage" their mother or help a doctor or nursing home get permission for a pill or procedure they feel is in the best interest of a patient.
Sent 15: Good news: Oklahoma now has a Public Guardianship Program, albeit unfunded, that will supply lawyers to perform this rights-monitoring process Oklahoma grandparents should be able to enjoy their grandchildren, not raise them.
Sent 16: But owing to the social problems of divorce and drug use, grandparents are increasingly being called on to raise their grandchildren because of missing parents.
Sent 17: Adding to the physical, emotional and financial burden they take on, grandparents face legal problems.
Sent 18: All the decisions parents made without a second thought now require evidence of legal authority when made by grandparents.
Question: Where will this year's Senior Day be held?.

A: 2, 3.

Q: Paragraph- Sent 1: On December 4, as news came in about the discoveries in Jordan, National Security Council (NSC) Counterterrorism Coordinator Richard Clarke wrote Berger, "If George's [Tenet's] story about a planned series of UBL attacks at the Millennium is true, we will need to make some decisions NOW."Sent 2: He told us he held several conversations with President Clinton during the crisis.
Sent 3: He suggested threatening reprisals against the Taliban in Afghanistan in the event of any attacks on U.S. interests, anywhere, by Bin Ladin.
Sent 4: He further proposed to Berger that a strike be made during the last week of 1999 against al Qaeda camps in Afghanistan-a proposal not adopted.
Sent 5: Warned by the CIA that the disrupted Jordanian plot was probably part of a larger series of attacks intended for the millennium, some possibly involving chemical weapons, the Principals Committee met on the night of December 8 and decided to task Clarke's Counterterrorism Security Group (CSG) to develop plans to deter and disrupt al Qaeda plots.
Sent 6: Michael Sheehan, the State Department member of the CSG, communicated warnings to the Taliban that they would be held responsible for future al Qaeda attacks."Sent 7: Mike was not diplomatic," Clarke reported to Berger.
Sent 8: With virtually no evidence of a Taliban response, a new approach was made to Pakistan.
Sent 9: 13 General Anthony Zinni, the commander of Central Command (CENTCOM), was designated as the President's special envoy and sent to ask General Musharraf to "take whatever action you deem necessary to resolve the Bin Laden problem at the earliest possible time."Sent 10: But Zinni came back emptyhanded.
Sent 11: As Ambassador William Milam reported from Islamabad, Musharraf was "unwilling to take the political heat at home."Sent 12: The CIA worked hard with foreign security services to detain or at least keep an eye on suspected Bin Ladin associates.
Sent 13: Tenet spoke to 20 of his foreign counterparts.
Sent 14: Disruption and arrest operations were mounted against terrorists in eight countries.
Sent 15: In mid-December, President Clinton signed a Memorandum of Notification (MON) giving the CIA broader authority to use foreign proxies to detain Bin Ladin lieutenants, without having to transfer them to U.S. custody.
Sent 16: The authority was to capture, not kill, though lethal force might be used if necessary.16Tenet would later send a message to all CIA personnel overseas, saying, "The threat could not be more real.
