instruction:
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 (", ").
question:
Paragraph- Sent 1: The hijackers attacked at 9:28.
Sent 2: While traveling 35,000 feet above eastern Ohio, United 93 suddenly dropped 700 feet.
Sent 3: Eleven seconds into the descent, the FAA's air traffic control center in Cleveland received the first of two radio transmissions from the aircraft.
Sent 4: During the first broadcast, the captain or first officer could be heard declaring "Mayday" amid the sounds of a physical struggle in the cockpit.
Sent 5: The second radio transmission, 35 seconds later, indicated that the fight was continuing.
Sent 6: The captain or first officer could be heard shouting:" Hey get out of here-get out of here-get out of here."Sent 7: On the morning of 9/11, there were only 37 passengers on United 93-33 in addition to the 4 hijackers.
Sent 8: This was below the norm for Tuesday mornings during the summer of 2001.
Sent 9: But there is no evidence that the hijackers manipulated passenger levels or purchased additional seats to facilitate their operation.
Sent 10: The terrorists who hijacked three other commercial flights on 9/11 operated in five-man teams.
Sent 11: They initiated their cockpit takeover within 30 minutes of takeoff.
Sent 12: On Flight 93, however, the takeover took place 46 minutes after takeoff and there were only four hijackers.
Sent 13: The operative likely intended to round out the team for this flight, Mohamed al Kahtani, had been refused entry by a suspicious immigration inspector at Florida's Orlando International Airport in August.
Sent 14: Because several passengers on United 93 described three hijackers on the plane, not four, some have wondered whether one of the hijackers had been able to use the cockpit jump seat from the outset of the flight.
Sent 15: FAA rules allow use of this seat by documented and approved individuals, usually air carrier or FAA personnel.
Sent 16: We have found no evidence indicating that one of the hijackers, or anyone else, sat there on this flight.
Sent 17: All the hijackers had assigned seats in first class, and they seem to have used them.
Sent 18: We believe it is more likely that Jarrah, the crucial pilot-trained member of their team, remained seated and inconspicuous until after the cockpit was seized; and once inside, he would not have been visible to the passengers.
Question: Where and when was the first 9/11 attack?.
answer:
1, 2, 7.

question:
Paragraph- Sent 1: The bar was manned by an expensive humanoid robot.
Sent 2: It turned toward Sarah's wave and acknowledged her with a nod, moments later setting a fluted glass of sparkling liquid in front of her.
Sent 3: I marveled at the robot's smoothness and coordination.
Sent 4: Clearly, it was a high-end model.
Sent 5: Sarah transferred the glass to my free hand and pulled me away from the bar for more introductions, with Alexis trailing after us.
Sent 6: I spent the evening listening, mostly.
Sent 7: Listening and stuffing my face with all the bits of fine food provided.
Sent 8: No one minded; Sarah's inner circle was content to fill our circle of couches with plenty of chatter.
Sent 9: Ray, a plump man who was grey where he wasn't bald.
Sent 10: Zheng, short and dark and lean, with a very intense gaze.
Sent 11: He made me a little uncomfortable.
Sent 12: Kishori, petite, her hair strung out in a series of braids that reached nearly to her waist.
Sent 13: I categorized them based on their appearances, hoping I'd be able to pick them out of the crowd again later.
Sent 14: Most of their chatter was meaningless to mestories of day-to-day activities, how so-and-so had been seen in so-and-so's table at lunch and my wasn't that a surprise, and why hadn't the chef concocted this delectable a selection of appetizers for the dance the other night, but of course those rolled meat pastries reminded one of the pastries back on Earth, didn't they, and this was somehow an interesting fact.
Sent 15: After the first half-hour, I stopped expending effort to keep names and stories and gossip straight.
Sent 16: I wasn't learning anything useful.
Sent 17: I could have started asking questions, but I wanted to get my bearings first.
Sent 18: Tonight was for observation.
Sent 19: I didn't bother trying to seek out a different group of potentially more interesting people, though.
Sent 20: They all looked the same: clusters of social butterflies surrounded by the less apt, the hangers-on, the circle with whom the gossip was shared.
Question: who was the bartender at this bar?.
answer:
1.

question:
Paragraph- Sent 1: After arriving in New York City, Einstein was taken to various places and events, including Chinatown, a lunch with the editors of the New York Times, and a performance of Carmen at the Metropolitan Opera, where he was cheered by the audience on his arrival.
Sent 2: During the days following, he was given the keys to the city by Mayor Jimmy Walker and met the president of Columbia University, who described Einstein as "the ruling monarch of the mind."Sent 3: Harry Emerson Fosdick, pastor at New York's Riverside Church, gave Einstein a tour of the church and showed him a full-size statue that the church made of Einstein, standing at the entrance.
Sent 4: Also during his stay in New York, he joined a crowd of 15,000 people at Madison Square Garden during a Hanukkah celebration.
Sent 5: Einstein next traveled to California where he met Caltech president and Nobel laureate, Robert A. Millikan.
Sent 6: His friendship with Millikan was "awkward", as Millikan "had a penchant for patriotic militarism," where Einstein was a pronounced pacifist.
Sent 7: During an address to Caltech's students, Einstein noted that science was often inclined to do more harm than good.
Sent 8: This aversion to war also led Einstein to befriend author Upton Sinclair and film star Charlie Chaplin, both noted for their pacifism.
Sent 9: Carl Laemmle, head of Universal Studios, gave Einstein a tour of his studio and introduced him to Chaplin.
Sent 10: They had an instant rapport, with Chaplin inviting Einstein and his wife, Elsa, to his home for dinner.
Sent 11: Chaplin said Einstein's outward persona, calm and gentle, seemed to conceal a "highly emotional temperament," from which came his "extraordinary intellectual energy."Sent 12: Chaplin also remembers Elsa telling him about the time Einstein conceived his theory of relativity.
Sent 13: During breakfast one morning, he seemed lost in thought and ignored his food.
Sent 14: She asked him if something was bothering him.
Sent 15: He sat down at his piano and started playing.
Sent 16: He continued playing and writing notes for half an hour, then went upstairs to his study, where he remained for two weeks, with Elsa bringing up his food.
Sent 17: At the end of the two weeks he came downstairs with two sheets of paper bearing his theory.
Sent 18: Chaplin's film, City Lights, was to premier a few days later in Hollywood, and Chaplin invited Einstein and Elsa to join him as his special guests.
