Input: Consider Input: Paragraph- Sent 1: Alexander earned the epithet "The Great" due to his unparalleled success as a military commander.
Sent 2: He never lost a battle, despite typically being outnumbered.
Sent 3: This was due to use of terrain, phalanx and cavalry tactics, bold strategy, and the fierce loyalty of his troops.
Sent 4: The Macedonian phalanx, armed with the sarissa, a spear 6 metres (20 ft) long, had been developed and perfected by Philip II through rigorous training, and Alexander used its speed and maneuverability to great effect against larger but more disparate Persian forces.
Sent 5: Alexander also recognized the potential for disunity among his diverse army, which employed various languages and weapons.
Sent 6: He overcame this by being personally involved in battle, in the manner of a Macedonian king.
Sent 7: In his first battle in Asia, at Granicus, Alexander used only a small part of his forces, perhaps 13,000 infantry with 5,000 cavalry, against a much larger Persian force of 40,000.
Sent 8: Alexander placed the phalanx at the center and cavalry and archers on the wings, so that his line matched the length of the Persian cavalry line, about 3 km (1.86 mi).
Sent 9: By contrast, the Persian infantry was stationed behind its cavalry.
Sent 10: This ensured that Alexander would not be outflanked, while his phalanx, armed with long pikes, had a considerable advantage over the Persian's scimitars and javelins.
Sent 11: Macedonian losses were negligible compared to those of the Persians.
Sent 12: At Issus in 333 BC, his first confrontation with Darius, he used the same deployment, and again the central phalanx pushed through.
Sent 13: Alexander personally led the charge in the center, routing the opposing army.
Sent 14: At the decisive encounter with Darius at Gaugamela, Darius equipped his chariots with scythes on the wheels to break up the phalanx and equipped his cavalry with pikes.
Sent 15: Alexander arranged a double phalanx, with the center advancing at an angle, parting when the chariots bore down and then reforming.
Sent 16: The advance was successful and broke Darius' center, causing the latter to flee once again.
Sent 17: When faced with opponents who used unfamiliar fighting techniques, such as in Central Asia and India, Alexander adapted his forces to his opponents' style.
Sent 18: Thus, in Bactria and Sogdiana, Alexander successfully used his javelin throwers and archers to prevent outflanking movements, while massing his cavalry at the center.
Question: Why did Alexander only use a small part of his forces in his first battle in Asia?.

Output: Alexander placed the phalanx at the center and cavalry and archers on the wings, so that his line matched the length of the Persian cavalry line, which ensured his army would not be out flanked.

Input: Consider Input: Paragraph- Sent 1: Alien Planet starts out with an interstellar spacecraft named Von Braun , leaving Earth's orbit .
Sent 2: Traveling at 20 % the speed of light , it reaches Darwin IV in 42 years .
Sent 3: Upon reaching orbit , it deploys the Darwin Reconnaissance Orbiter , Which looks for potential landing sites for the probes .
Sent 4: The first probe , Balboa , explodes along with its lifting body transport during entry , because one of its wings failed to unfold .
Sent 5: Two backup probes , Leonardo da Vinci and Isaac Newton , successfully land on the planet , and learn much about its bizarre indigenous lifeforms , including an apparently sapient species .
Sent 6: The robotic probes sent out to research on Darwin IV are called Horus Probes .
Sent 7: Each Horus probe consists of an { { convert } } long inflatable , hydrogen-filled balloon , Which is covered with solar receptors , a computer ' brain ' , a ' head ' covered with sensors , and several smaller robots that can be sent to places too dangerous for the probes themselves .
Sent 8: The probes have a limited degree of artificial intelligence , very similar to the ' processing power ' of a 4-year-old .
Sent 9: All the real thinking is done by a supercomputer in the orbiting Von Braun .
Sent 10: The probes are programmed with different personalities ; Ike is more cautious , while Leo is the risk-taker .
Sent 11: The two probes are also equipped with a holographic message that will be projected to any sentient life found on Darwin .
Sent 12: After the two probes inflate their gas-bags , they encounter a voracious Arrowtongue and watch it pursue a Gyrosprinter .
Question: What were the names of the three probes deployed by the Van Braun spacecraft?.

Output: Balboa, Leonardo da Vinci, and Isaac Newton.

Input: Consider Input: Paragraph- Sent 1: Clarifying the Record The defense of U.S. airspace on 9/11 was not conducted in accord with preexisting training and protocols.
Sent 2: It was improvised by civilians who had never handled a hijacked aircraft that attempted to disappear, and by a military unprepared for the transformation of commercial aircraft into weapons of mass destruction.
Sent 3: As it turned out, the NEADS air defenders had nine minutes' notice on the first hijacked plane, no advance notice on the second, no advance notice on the third, and no advance notice on the fourth.
Sent 4: We do not believe that the true picture of that morning reflects discredit on the operational personnel at NEADS or FAA facilities.
Sent 5: NEADS commanders and officers actively sought out information, and made the best judgments they could on the basis of what they knew.
Sent 6: Individual FAA controllers, facility managers, and Command Center managers thought outside the box in recommending a nationwide alert, in ground-stopping local traffic, and, ultimately, in deciding to land all aircraft and executing that unprecedented order flawlessly.
Sent 7: More than the actual events, inaccurate government accounts of those events made it appear that the military was notified in time to respond to two of the hijackings, raising questions about the adequacy of the response.
Sent 8: Those accounts had the effect of deflecting questions about the military's capacity to obtain timely and accurate information from its own sources.
Sent 9: In addition, they overstated the FAA's ability to provide the military with timely and useful information that morning.
Sent 10: In public testimony before this Commission in May 2003, NORAD officials stated that at 9:16, NEADS received hijack notification of United 93 from the FAA.
Sent 11: This statement was incorrect.
Sent 12: There was no hijack to report at 9:16.
Sent 13: United 93 was proceeding normally at that time.
Sent 14: In this same public testimony, NORAD officials stated that at 9:24, NEADS received notification of the hijacking of American 77.
Sent 15: This statement was also incorrect.
Sent 16: The notice NEADS received at 9:24 was that American 11 had not hit the World Trade Center and was heading for Washington, D.C. In their testimony and in other public accounts, NORAD officials also stated that the Langley fighters were scrambled to respond to the notifications about American 77,178 United 93, or both.
Sent 17: These statements were incorrect as well.
Sent 18: The fighters were scrambled because of the report that American 11 was heading south, as is clear not just from taped conversations at NEADS but also from taped conversations at FAA centers; contemporaneous logs compiled at NEADS, Continental Region headquarters, and NORAD; and other records.
Question: Who coordinated the defense of US airspace on September 11?.
Output: FAA.
