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: A government-sponsored coup last year made Bruce Iwasaki and Neal Dudovitz the kings of Los Angeles County's federally funded legal aid community.
Sent 2: The two men emerged atop a changed landscape that resulted from a decade of begging for a share of shrinking public dollars doled out by an unsympathetic GOP-controlled Congress.
Sent 3: That era was capped in 1998, when the Legal Services Corp. forced 275 legal aid providers nationwide to combine into 179.
Sent 4: To comply with the orders from their main funding source, a new species of poverty lawyer emerged - a tech-savvy and button-down breed who swapped neighborhood walkin offices for toll-free phone lines, self-help kiosks and Internet access to legal advice.
Sent 5: While some organizations made the dramatic change look effortless, for others, it did not come easy.
Sent 6: And few programs provide more dramatic illustrations of the promise and pitfalls of government-funded legal services than Los Angeles County's two largest providers of federally funded services - Legal Aid Foundation of Los Angeles and Pacoima-based Neighborhood Legal Services of Los Angeles County.
Sent 7: From his offices in Koreatown, Iwasaki, a soft-spoken former O'Melveny & Myers attorney, quietly engineered a merger between a much smaller Legal Aid Society of Long Beach and his program, the Legal Aid Foundation of Los Angeles.
Sent 8: The merger was completed peacefully within a year of the federal order.
Sent 9: Today, the programs operate seamlessly, offering new innovations - including toll-free multilingual phone advisers, expanded hours for domestic-violence clinics, and renewed immigration and consumer aid - built on the foundations of the old program.
Sent 10: The organization is Los Angeles' largest government-funded group, with a budget of $11 million leveraged into $40 million in legal services to the poor.
Question: Who was the owner of Legal Aid Society of Long Beach before the merger?.

Paragraph- Sent 1: Right after the Pentagon was hit, NEADS learned of another possible hijacked aircraft.
Sent 2: It was an aircraft that in fact had not been hijacked at all.
Sent 3: After the second World Trade Center crash, Boston Center managers recognized that both aircraft were transcontinental 767 jetliners that had departed Logan Airport.
Sent 4: Remembering the "we have some planes" remark, Boston Center guessed that Delta 1989 might also be hijacked.
Sent 5: Boston Center called NEADS at 9:41 and identified Delta 1989, a 767 jet that had left Logan Airport for Las Vegas, as a possible hijack.
Sent 6: NEADS warned the FAA's Cleveland Center to watch Delta 1989.
Sent 7: The Command Center and FAA headquarters watched it too.
Sent 8: During the course of the morning, there were multiple erroneous reports of hijacked aircraft.
Sent 9: The report of American 11 heading south was the first; Delta 1989 was the second.
Sent 10: NEADS never lost track of Delta 1989, and even ordered fighter aircraft from Ohio and Michigan to intercept it.
Sent 11: The flight never turned off its transponder.
Sent 12: NEADS soon learned that the aircraft was not hijacked, and tracked Delta 1989 as it reversed course over Toledo, headed east, and landed in Cleveland.
Sent 13: But another aircraft was heading toward Washington, an aircraft about which NORAD had heard nothing: United 93.
Sent 14: United Airlines Flight 93 FAA Awareness.
Sent 15: At 9:27, after having been in the air for 45 minutes, United 93 acknowledged a transmission from the Cleveland Center controller.
Sent 16: This was the last normal contact the FAA had with the flight.
Sent 17: Less than a minute later, the Cleveland controller and the pilots of aircraft in the vicinity heard "a radio transmission of unintelligible sounds of possible screaming or a struggle from an unknown origin."Sent 18: The controller responded, seconds later: "Somebody call Cleveland?"This was followed by a second radio transmission, with sounds of screaming.
Question: Which air traffic center communicated with United 93?.

Paragraph- Sent 1: Energy is the ability to do work.
Sent 2: Another way to say this is, the ability to cause change.
Sent 3: Work is done when a force is used to move something.
Sent 4: When work is done, energy is transferred.
Sent 5: This transfer occurs between one object and another.
Sent 6: For example, a batter swings a bat and transfers energy.
Sent 7: She transfers her energy to the bat.
Sent 8: The moving bat, in turn, transfers energy to the ball.
Sent 9: Energy is measured in the Joule (J).
Sent 10: Energy exists in many forms.
Sent 11: One form of energy is called mechanical.
Sent 12: Mechanical energy is the energy of motion.
Sent 13: This type of energy can also include things that are not yet in motion.
Sent 14: In these cases, they have only a potential to be in motion.
Sent 15: In most cases, this ability comes from a position.
Sent 16: A rock sitting on top of a cliff has potential energy.
Sent 17: It is more than just the ability.
Sent 18: A rock sitting on the ground could move if someone picked it up.
Question: Describe potential energy and give an example.
