Question: 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?.

Answer: 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.

Sent 2: Earlier, in 1921, he was asked by the biochemist and president of the World Zionist Organization, Chaim Weizmann, to help raise funds for the planned university.
Sent 3: He also submitted various suggestions as to its initial programs.
Sent 4: Among those, he advised first creating an Institute of Agriculture in order to settle the undeveloped land.
Sent 5: That should be followed, he suggested, by a Chemical Institute and an Institute of Microbiology, to fight the various ongoing epidemics such as malaria, which he called an "evil" that was undermining a third of the country's development.
Sent 6: Establishing an Oriental Studies Institute, to include language courses given in both Hebrew and Arabic, for scientific exploration of the country and its historical monuments, was also important.
Sent 7: Chaim Weizmann later became Israel's first president.
Sent 8: Upon his death while in office in November 1952 and at the urging of Ezriel Carlebach, Prime Minister David Ben-Gurion offered Einstein the position of President of Israel, a mostly ceremonial post.
Sent 9: The offer was presented by Israel's ambassador in Washington, Abba Eban, who explained that the offer "embodies the deepest respect which the Jewish people can repose in any of its sons".
Sent 10: Einstein declined, and wrote in his response that he was "deeply moved", and "at once saddened and ashamed" that he could not accept it. 
Question: How did Einstein help establish the University of Jerusalem?.

Answer: Helped raise funds and suggestions for initial programs.


Question: Paragraph- Sent 1: In the popular mind, the history of Hong Kong, long the entryway to China for Westerners, begins in 1841 with the British occupation of the territory.
Sent 2: However, it would be wrong to dismiss the long history of the region itself.
Sent 3: Archaeologists today are working to uncover Hong Kong's past, which stretches back thousands of years.
Sent 4: You can get a glimpse into that past at Lei Cheng Uk Museum's 1,600-year-old burial vault on the mainland just north of Kowloon.
Sent 5: In 1992, when construction of the airport on Chek Lap Kok was begun, a 2,000-year-old village, Pak Mong, was discovered, complete with artifacts that indicated a sophisticated rural society.
Sent 6: An even older Stone Age site was discovered on Lamma Island in 1996.
Sent 7: While Hong Kong remained a relative backwater in early days, nearby Guangzhou (Canton) was developing into a great trading city with connections in India and the Middle East.
Sent 8: By a.d.
Sent 9: 900, the Hong Kong islands had become a lair for pirates preying on the shipping in the Pearl River Delta and causing a major headache for burgeoning Guangzhou; small bands of pirates were still operating into the early years of the 20th century.
Sent 10: In the meantime, the mainland area was being settled by incomers, the "Five Great Clans": Tang, Hau, Pang, Liu, and Man.
Sent 11: First to arrive was the Tang clan, which established a number of walled villages in the New Territories that still exist today.
Sent 12: You can visit Kat Hing Wai and Lo Wai, villages with their walls still intact.
Sent 13: Adjacent to Lo Wai is the Tang Chung Ling Ancestral Hall, built in the 16th century, which is still the center of clan activities.
Sent 14: The first Europeans to arrive in the Pearl River Delta were the Portuguese, who settled in Macau in 1557 and for several centuries had a monopoly on trade between Asia, Europe, and South America.
Sent 15: As Macau developed into the greatest port in the East, it also became a base for Jesuit missionaries; it was later a haven for persecuted Japanese Christians.
Sent 16: While Christianity was not a great success in China, it made local headway, evidenced today by the numerous Catholic churches in Macau's historic center.
Sent 17: Intermarriage with the local Chinese created a community of Macanese, whose culture can still be seen in Macau's architecture and cuisine. 
Question: Whose missionary efforts resulted in the spread of Catholicism in Macau?.

Answer:
The Jesuits.
