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.The following quote would best fit at the end of which paragraph? "You just can't learn this kind of thing in a regular classroom."

DIRECTIONS: Chооse the cоrrect аnswer for eаch question. Shаrk Attack [A] The morning had started out well for 41-year-old surfer Sam Edwardes. Sam was with his housemate Dane near Belongil Beach in the Australian state of New South Wales. The waves looked good and Sam was sitting on his surfboard, waiting for the right time to begin his first attempt.[B] Suddenly, horror struck. A great white shark rose from beneath the surface and pushed him off his board with great force. Edwardes felt a sharp pain in his leg and began to scream. As quickly as he possibly could, he got back on his board and began paddling toward the beach. As he paddled toward the shore, he shouted for help and warned other surfers about the shark.[C] When he arrived on the beach, his housemate and others on the sand realized how bad the damage was. The scene was extremely frightening. The shark had bitten a large piece out of his leg and blood was spilling out quickly. The shark had also taken a large chunk out of his surfboard.[D] Fortunately, Edwardes and those around him remained remarkably calm. His housemate and others on the beach called for an ambulance and helped stop the blood flow with a number of surfing ropes. Although Edwardes was confused about what was happening to him, he stayed calm enough to thank those around him for helping him. He was soon airlifted1 to a nearby hospital.[E] After surgery lasting four and a half hours, it became clear that Edwardes had been extremely lucky. The shark had missed some of the most important arteries2 and nerves.3 Because of this, not only was he able to survive, but there is a good chance that he will be able to surf again in the future. 1 To be airlifted is to be transported by airplane or helicopter. 2 An artery is a tube in the body that carries blood from the heart to other parts of the body.3 A nerve is a part of the body that sends messages between the brain and other parts of the body, allowing for movement and feeling.What is the passage mainly about?
