Sent 16: He founded some twenty cities that bore his name, most notably Alexandria in Egypt.
Sent 17: Alexander's settlement of Greek colonists and the resulting spread of Greek culture in the east resulted in a new Hellenistic civilization, aspects of which were still evident in the traditions of the Byzantine Empire in the mid-15th century and the presence of Greek speakers in central and far eastern Anatolia until the 1920s.

question:
Paragraph- Sent 1: Born on May 11, 1975, in Mazraa, Lebanon, Ziad Jarrah came from an affluent family and attended private, Christian schools.
Sent 2: Like Atta, Binalshibh, and Shehhi, Jarrah aspired to pursue higher education in Germany.
Sent 3: In April 1996, he and a cousin enrolled at a junior college in Greifswald, in northeastern Germany.
Sent 4: There Jarrah met and became intimate with Aysel Senguen, the daughter of Turkish immigrants, who was preparing to study dentistry.
Sent 5: Even with the benefit of hindsight, Jarrah hardly seems a likely candidate for becoming an Islamic extremist.
Sent 6: Far from displaying radical beliefs when he first moved to Germany, he arrived with a reputation for knowing where to find the best discos and beaches in Beirut, and in Greifswald was known to enjoy student parties and drinking beer.
Sent 7: Although he continued to share an apartment in Greifswald with his cousin, Jarrah was mostly at Senguen's apartment.
Sent 8: Witnesses interviewed by German authorities after 9/11, however, recall that Jarrah started showing signs of radicalization as early as the end of 1996.
Sent 9: After returning from a trip home to Lebanon, Jarrah started living more strictly according to the Koran.
Sent 10: He read brochures in Arabic about jihad, held forth to friends on the subject of holy war, and professed disaffection with his previous life and a desire not to leave the world "in a natural way."Sent 11: In September 1997, Jarrah abruptly switched his intended course of study from dentistry to aircraft engineering-at the Technical University of Hamburg-Harburg.
Sent 12: His motivation for this decision remains unclear.
Sent 13: The rationale he expressed to Senguen-that he had been interested in aviation since playing with toy airplanes as a child-rings somewhat hollow.
Sent 14: In any event, Jarrah appears already to have had Hamburg contacts by this time, some of whom may have played a role in steering him toward Islamic extremism.
Sent 15: Following his move to Hamburg that fall, he began visiting Senguen in Greifswald on weekends, until she moved to the German city of Bochum one year later to enroll in dental school.
Sent 16: Around the same time, he began speaking increasingly about religion, and his visits to Senguen became less and less frequent.
Sent 17: He began criticizing her for not being religious enough and for dressing too provocatively.
Sent 18: He grew a full beard and started praying regularly.
Question: WHO DID JARRAH MET AND BECOME INTAMATE WITH?.
answer:
4.

question:
Paragraph- Sent 1: The Glory of Melaka: In the early days, if you were not a pirate or a mosquito, Melaka was not much of a place to live.
Sent 2: The land was infertile, just a swampy plain, the river small and sluggish.
Sent 3: But it had a sheltered harbor, protected from the monsoons by neighboring Sumatra.
Sent 4: Later, the strategic location and deep-water channel close to the coast brought in the bigger vessels of the trade-wind traffic crossing the Indian Ocean.
Sent 5: The first to realize the larger commercial potential, as so often throughout the country's subsequent history, were the Chinese.
Sent 6: In 1409, under a new directive from Emperor Chu Ti to pursue trade in the South Seas and the Indian Ocean, a Chinese fleet of 50 ships headed by Admiral Cheng Ho called in at Melaka.
Sent 7: They made Parameswara an offer he could not refuse: port facilities and an annual financial tribute in exchange for Chinese protection against the marauding Thais.
Sent 8: In 1411, Parameswara took the money to Beijing himself, and the emperor gratefully made him a vassal king.
Sent 9: Twenty years later, the Chinese withdrew again from the South Seas trade.
Sent 10: The new ruler of Melaka, Sri Maharajah, switched his allegiance to the Muslim trading fraternity by marrying into the Muslim faith, wedding the daughter of a sultan in Sumatra.
Sent 11: Islam won its place in Malaya not by conquestas had been the case in North Africa and Europebut by trade, dynastic alliances, and peaceful preaching.
Sent 12: Bengali peddlers had already brought the faith to the east coast.
Sent 13: In Melaka and throughout the peninsula, Islam thrived as a strong, male-dominated religion of individuality, offering dynamic leadership and preaching brotherhood and self-relianceall qualities ideally suited to the coastal trade.
Sent 14: At the same time, Sufi mystics synthesized Islamic teaching with local Malay traditions of animistic magic and charisma, though Islam did not become the state religion until Muzaffar Shah became sultan of Melaka (14461459).
Sent 15: But the key figure in the sultanate was Tun Perak, bendahara (prime minister) and military commander.
Sent 16: He expanded Melaka's power along the west coast and down to Singapore and the neighboring Bintan islands.
Sent 17: He also had orang laut pirates patrolling the seas to extort tribute from passing ships.
