Input: Alexander earned the epithet "The Great" due to his unparalleled success as a military commander. He never lost a battle, despite typically being outnumbered. This was due to use of terrain, phalanx and cavalry tactics, bold strategy, and the fierce loyalty of his troops. 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. Alexander also recognized the potential for disunity among his diverse army, which employed various languages and weapons. He overcame this by being personally involved in battle, in the manner of a Macedonian king. 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. 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). By contrast, the Persian infantry was stationed behind its cavalry. 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. Macedonian losses were negligible compared to those of the Persians. At Issus in 333 BC, his first confrontation with Darius, he used the same deployment, and again the central phalanx pushed through. Alexander personally led the charge in the center, routing the opposing army. 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. Alexander arranged a double phalanx, with the center advancing at an angle, parting when the chariots bore down and then reforming. The advance was successful and broke Darius' center, causing the latter to flee once again. When faced with opponents who used unfamiliar fighting techniques, such as in Central Asia and India, Alexander adapted his forces to his opponents' style. Thus, in Bactria and Sogdiana, Alexander successfully used his javelin throwers and archers to prevent outflanking movements, while massing his cavalry at the center.
"How did Alexander overcome the potential disunity amon his diverse army?" is "He overcome the potential disunity among his diverse army by being personally involved in battle"?
Output: yes
Input: The Principals Committee had its first meeting on al Qaeda on September 4. On the day of the meeting, Clarke sent Rice an impassioned personal note. He criticized U.S. counterterrorism efforts past and present. The "real question" before the principals, he wrote, was "are we serious about dealing with the al Qida threat? Is al Qida a big deal? Decision makers should imagine themselves on a future day when the CSG has not succeeded in stopping al Qida attacks and hundreds of Americans lay dead in several countries, including the US," Clarke wrote. "What would those decision makers wish that they had done earlier? That future day could happen at any time." Clarke then turned to the Cole." The fact that the USS Cole was attacked during the last Administration does not absolve us of responding for the attack," he wrote. "Many in al Qida and the Taliban may have drawn the wrong lesson from the Cole: that they can kill Americans without there being a US response, without there being a price."
"What two things did Clarke urge decision makers to do because the future could happen at any time?" is "Assess the threats of Al qida"?
Output: no
Input: Fossils give clues about major geological events. Fossils can also give clues about past climates. Fossils of ocean animals on the top of a mountain? Ocean animals have been found on the Earths tallest mountain. Its hard to believe, but it is true. These fossils were found at the top of Mt. Everest. Mt. Everest is the highest mountain on Earth. These fossils showed that this entire area was once at the bottom of a sea. It can only mean that Mt. Everest was uplifted. In fact, the entire Himalaya mountain range was raised. It was forced up from the collision of two continents. Fossils of plants are found in Antarctica. Now, Antarctica is almost completely covered with ice. Plants do not grow in Antarctica. According to fossils, they once did. This means that Antarctica was once much warmer than it is now. These fossils tell us about Antarcticas past climate.
"Where is an unexpected location fossils have been found?" is "America"?
Output:
no
