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 (", ").

Paragraph- Sent 1: About 20 minutes later, at 7:35, another passenger for Flight 77, Hani Hanjour, placed two carry-on bags on the X-ray belt in the Main Terminal's west checkpoint, and proceeded, without alarm, through the metal detector.
Sent 2: A short time later, Nawaf and Salem al Hazmi entered the same checkpoint.
Sent 3: Salem al Hazmi cleared the metal detector and was permitted through; Nawaf al Hazmi set off the alarms for both the first and second metal detectors and was then hand-wanded before being passed.
Sent 4: In addition, his over-the-shoulder carry-on bag was swiped by an explosive trace detector and then passed.
Sent 5: The video footage indicates that he was carrying an unidentified item in his back pocket, clipped to its rim.
Sent 6: When the local civil aviation security office of the Federal Aviation Administration (FAA) later investigated these security screening operations, the screeners recalled nothing out of the ordinary.
Sent 7: They could not recall that any of the passengers they screened were CAPPS selectees.
Sent 8: We asked a screening expert to review the videotape of the hand-wanding, and he found the quality of the screener's work to have been "marginal at best."Sent 9: The screener should have "resolved" what set off the alarm; and in the case of both Moqed and Hazmi, it was clear that he did not.
Sent 10: At 7:50, Majed Moqed and Khalid al Mihdhar boarded the flight and were seated in 12A and 12B in coach.
Sent 11: Hani Hanjour, assigned to seat 1B (first class), soon followed.
Sent 12: The Hazmi brothers, sitting in 5E and 5F, joined Hanjour in the first-class cabin.
Sent 13: Newark: United 93.
Sent 14: Between 7:03 and 7:39, Saeed al Ghamdi, Ahmed al Nami, Ahmad al Haznawi, and Ziad Jarrah checked in at the United Airlines ticket counter for Flight 93, going to Los Angeles.
Sent 15: Two checked bags; two did not.
Sent 16: Haznawi was selected by CAPPS.
Sent 17: His checked bag was screened for explosives and then loaded on the plane.
Sent 18: The four men passed through the security checkpoint, owned by United Airlines and operated under contract by Argenbright Security.
Question: A screening expert said that the screener's work was marginal at best and that the screener should have done what?.

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?.

Paragraph- Sent 1: Einstein was displeased with quantum theory and mechanics (the very theory he helped create), despite its acceptance by other physicists, stating that God "is not playing at dice."Sent 2: Einstein continued to maintain his disbelief in the theory, and attempted unsuccessfully to disprove it until he died at the age of 76.
Sent 3: In 1917, at the height of his work on relativity, Einstein published an article in Physikalische Zeitschrift that proposed the possibility of stimulated emission, the physical process that makes possible the maser and the laser.
Sent 4: This article showed that the statistics of absorption and emission of light would only be consistent with Planck's distribution law if the emission of light into a mode with n photons would be enhanced statistically compared to the emission of light into an empty mode.
Sent 5: This paper was enormously influential in the later development of quantum mechanics, because it was the first paper to show that the statistics of atomic transitions had simple laws.
Sent 6: Einstein discovered Louis de Broglie's work, and supported his ideas, which were received skeptically at first.
Sent 7: In another major paper from this era, Einstein gave a wave equation for de Broglie waves, which Einstein suggested was the Hamilton-Jacobi equation of mechanics.
Sent 8: This paper would inspire Schrodinger's work of 1926.
Question: What did Einstein publish in that showed the statistics of absorption and proposed the possibility of stimulated emission?.
