DIRECTIONS: Chооse the cоrrect аnswer for eаch question.An Incredible Journey[A] The Polos - Mаrco, his father, Niccolo, and his uncle, Maffeo - had been traveling for three and a half years when they finally achieved their objective - a long-awaited meeting with the powerful Mongol leader Kublai Khan. The historic event took place in 1275 at the Khan's luxurious summer capital in Shangdu, in what is now northern China. Kublai Khan was surprisingly informal as he greeted his tired guests: "Welcome, gentlemen! Please stand up. How've you been? How was the trip?" [B] Marco Polo's trip had, in fact, started more than 9,000 kilometers away in Venice when he was just a teenager. His father and uncle already knew Kublai Khan from a previous visit nine years earlier, when they had spent a short time in Shangdu. On this second trip, the Polos stayed for 17 years before they returned home. They made themselves useful to the Khan, and undertook various missions and tasks for him. It is likely that the Khan considered it an honor that these Europeans - who were rare in China - had made this extremely difficult journey, and he took the opportunity to make good use of their skills and knowledge. [C] While he was in the service of Kublai Khan, "the most powerful man in people and in lands and in treasure that ever was in the world," Marco Polo was able to learn and experience many things that were new to Europeans. In his travel journal, he wrote that Kublai Khan's palace was the greatest he had ever seen. He admired the Khan's recently completed new capital - Daidu - whose streets were "so straight and so broad." The city was located in what is now the center of Beijing, and Kublai Khan's city planning can still be perceived in the straight, broad streets of China's modern capital.[D] We learn from Marco Polo that, in the administration of his empire, Kublai Khan made use of a fast and simple message system. Horse riders spaced every 40 kilometers allowed messages to cover 500 kilometers a day. As soon as one horse had run 40 kilometers, the next horse would run the next 40 kilometers, and so on. Marco also learned the secret of asbestos cloth, which is made from a mineral and doesn't catch fire. Paper money also took him by surprise, since it was not yet used in the West at that time. Homes were heated with "black stones ... which burn like logs." Those stones were coal - unknown in most of Europe - and were so plentiful that many people had a hot bath three times a week.[E] Although the Khan did not want his visitors to leave, the Polos finally received permission to return home in 1292. Marco continued his observations while on the ocean voyage by way of Sumatra and India. After he returned home, Marco completed a book about his trip, full of details about his amazing cultural experiences. It was probably the single greatest contribution to geographical knowledge ever made to the West about the East. According to the passage, which of the following is true?

DIRECTIONS: Reаd the аrticle аnd select the best answer tо each questiоn. EARTH UNIVERSITY [A] Fоr many universities around the world, the college experience has become more environmentally friendly, from recycling to renewable energy use, to biking to class. But at EARTH University in eastern Costa Rica, it's the main focus of study.[B] "We're forming leaders to go out and influence their communities and their countries to take greater care of the Earth and change the world," said Jose Zaglul, the university's president. That may seem like a lofty mission for a small college of 417 students in a remote area. But the university is well-known for its excellent teaching methods and facilities.[C] The university has its own rain forest area and organic farm, so students can learn how their planet works while on campus. "It's as if on the first day of medical school, you go [and work in] the emergency room," university president Zaglul said. "You may not know the science yet, but [as a student] you're exposed to the environment from day one. Once you go back to the classroom, things make more sense."[D] The school's organic farm produces vegetables for the school cafeteria and local communities. It also produces food for pigs, cows, and chickens, and it raises a local fish called guapote. Panfilo Tabora, an EARTH University professor who heads the farm, says it was one of the first "teaching" organic farms. "All students have to come here and put in their shift, to question and compare things, innovate, and then implement what they have learned," Tabora said.Where is EARTH University located?
