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 (", ").

[Q]: Paragraph- Sent 1: He repeatedly calls on his followers to embrace martyrdom since "the walls of oppression and humiliation cannot be demolished except in a rain of bullets."Sent 2: For those yearning for a lost sense of order in an older, more tranquil world, he offers his "Caliphate" as an imagined alternative to today's uncertainty.
Sent 3: For others, he offers simplistic conspiracies to explain their world.
Sent 4: Bin Ladin also relies heavily on the Egyptian writer Sayyid Qutb.
Sent 5: A member of the Muslim Brotherhood executed in 1966 on charges of attempting to overthrow the government, Qutb mixed Islamic scholarship with a very superficial acquaintance with Western history and thought.
Sent 6: Sent by the Egyptian government to study in the United States in the late 1940s, Qutb returned with an enormous loathing of Western society and history.
Sent 7: He dismissed Western achievements as entirely material, arguing that Western society possesses "nothing that will satisfy its own conscience and justify its existence."Sent 8: Three basic themes emerge from Qutb's writings.
Sent 9: First, he claimed that the world was beset with barbarism, licentiousness, and unbelief (a condition he called jahiliyya, the religious term for the period of ignorance prior to the revelations given to the Prophet Mohammed).
Sent 10: Qutb argued that humans can choose only between Islam and jahiliyya.
Sent 11: Second, he warned that more people, including Muslims, were attracted to jahiliyya and its material comforts than to his view of Islam; jahiliyya could therefore triumph over Islam.
Sent 12: Third, no middle ground exists in what Qutb conceived as a struggle between God and Satan.
Sent 13: All Muslims-as he defined them-therefore must take up arms in this fight.
Sent 14: Any Muslim who rejects his ideas is just one more nonbeliever worthy of destruction.
Sent 15: Bin Ladin shares Qutb's stark view, permitting him and his followers to rationalize even unprovoked mass murder as righteous defense of an embattled faith.
Sent 16: Many Americans have wondered, "Why do 'they' hate us?"Sent 17: Some also ask, "What can we do to stop these attacks?"Sent 18: Bin Ladin and al Qaeda have given answers to both these questions.

[Q]: Paragraph- Sent 1: On 9/11, the defense of U.S. airspace depended on close interaction between two federal agencies: the FAA and the North American Aerospace Defense Command (NORAD).
Sent 2: The most recent hijacking that involved U.S. air traffic controllers, FAA management, and military coordination had occurred in 1993.90 In order to understand how the two agencies interacted eight years later, we will review their missions, command and control structures, and working relationship on the morning of 9/11.
Sent 3: FAA Mission and Structure.
Sent 4: As of September 11, 2001, the FAA was mandated by law to regulate the safety and security of civil aviation.
Sent 5: From an air traffic controller's perspective, that meant maintaining a safe distance between airborne aircraft.
Sent 6: Many controllers work at the FAA's 22 Air Route Traffic Control Centers.
Sent 7: They are grouped under regional offices and coordinate closely with the national Air Traffic Control System Command Center, located in Herndon, Virginia, which oversees daily traffic flow within the entire airspace system.
Sent 8: FAA headquarters is ultimately responsible for the management of the National Airspace System.
Sent 9: The Operations Center located at FAA headquarters receives notifications of incidents, including accidents and hijackings.
Sent 10: FAA Control Centers often receive information and make operational decisions independently of one another.
Sent 11: On 9/11, the four hijacked aircraft were monitored mainly by the centers in Boston, New York, Cleveland, and Indianapolis.
Sent 12: Each center thus had part of the knowledge of what was going on across the system.
Sent 13: What Boston knew was not necessarily known by centers in New York, Cleveland, or Indianapolis, or for that matter by the Command Center in Herndon or by FAA headquarters in Washington.
Sent 14: Controllers track airliners such as the four aircraft hijacked on 9/11 primarily by watching the data from a signal emitted by each aircraft's transponder equipment.
Sent 15: Those four planes, like all aircraft traveling above 10,000 feet, were required to emit a unique transponder signal while in flight.
Sent 16: On 9/11, the terrorists turned off the transponders on three of the four hijacked aircraft.
Sent 17: With its transponder off, it is possible, though more difficult, to track an aircraft by its primary radar returns.
Sent 18: But unlike transponder data, primary radar returns do not show the aircraft's identity and altitude.
Question: Name 3 Air Route Traffic Control Centers.
