Read the following article and select the best answer. Article: TV Shows and Long Bus Trips Long bus rides are like television shows. They have a beginning, a middle, and an end-- with ads thrown in every three or four minutes. The ads are unavoidable. They happen whether you want them or not. Every couple of minutes a billboard appears outside the bus window."Buy Super Clean Toothpaste.""Drink Good'n Wet Root Beer.""Fill up with Pacific Gas." Only if you sleep, which is equal to turning the television set off, are you spared the unending cry of "You Need It! Buy It Now!" The beginning of the ride is comfortable and somewhat exciting, even if you've traveled that way before. Usually some things have changed--new houses, new buildings, sometimes even a new road. The bus driver has a style of driving and it's fun to try to figure it out the first hour or so. If the driver is particularly daring, the ride can be as exciting as a suspense story. Will the driver pass the truck in time? Will the driver move into the right or the left-hand lane?After a while, of course, the excitement dies down. Sleeping for a while helps pass the middle hours of the ride. Food always makes bus rides more interesting. But you've got to be careful of what kind of food you eat. Too much salty food can make you very thirsty between stops. The end of the ride is somewhat like the beginning. You know it will soon be over and there's a kind of expectation and excitement in that. The seat, of course, has become harder as the hours have passed. By now you've sat with your legs crossed, with your hands in your lap, with your hands on the arm rests--even with your hands crossed behind your head. The end comes just at the right time. There are just no more ways to sit. Question: What is the purpose of this passage? - To talk about the similarities between long bus trips and TV shows. - To persuade you to take a long bus trip. - To display the differences between long bus trips and TV shows. - To describe the billboards along the road.

Read the following article and select the best answer. Article: Sir Edmund Hillary is best known for being the first, along with climbing partner Tenzing Norgay, to reach the top of Mount Everest . However, he also made many visits to Antarctica . In 1957, he led the first trip over ice to the South Pole. Hillary also helped his home country, New Zealand, build a research center on Antarctica, called Scott Base. He visited it in January 2007, when he was 87 years old. In the 1900s, many people like Hillary saw Antarctica as an exciting place. Scientists are interested in how glaciers flow and melt. They also worry that global warming is making glaciers melt faster. It has caused a 75 percent increase in ice loss in the last 10 years, according to a new study. Scientists say ice loss could cause water levels around the world to rise faster than expected. Ice is melting faster than expected because of global warming. Researchers in Antarctica are studying many other subjects too. Some use the cold weather and clear air as a way to study things that affect other parts of the globe. Antarctica has the cleanest air in the world. That allows scientists to compare the air there to the air in polluted places. Antarctica is the darkest place on earth, so it is a great place to study the stars. Some scientists are even studying penguin droppings . They have developed a new test to learn more about penguins' diets. Question: The final result of global warming is that _ . - there would be no ice - water levels could rise faster - the climate would become warm - the ocean would be polluted
water levels could rise faster

Q: Read the following article and select the best answer. Article: Nicaragua's Cerro Negro Volcano has erupted 23 times in the past 100 years,burying homes, crops and people in lava and ashes. But recently the black mountain has become a tourist draw, thanks to a newly invented extreme sport: volcano boarding. Thousands of thrill-seekers have climbed to the top of Cerro Negro, peered into its mouth, then zipped down its rough-and--rocky 41--degree slope on special boards. The volcano-boarding speed, set by an Israeli woman, is 54 mph. "Rushing down an active volcano is something that people expect." Said Anthony Alcalde, an expert volcano boarder. The sport was developed in the mid-2000s by Darryn Webb, an Australian who had climbed the nearby Cerro Negro but was looking for a faster way to get to the bottom. He tried sliding down on surfboards, snowboards, and even a refrgerrator door before inventing a sit-down board made of plywood. "At first, Darryn planned to use a snowboard," said Gemma Cope, a British woman who now runs Big Foot, which offers volcano boarding tours. "But he realized he couldn't cut an edge for there were little rocks everywhere. So he came up with the sitting-down option and realized he can go pretty fast. " Tourists,who are nearly all foreigners,pay $28 for the experience, which begins with a truck ride on dirt roads to Cerro Negr0.a 2,400-foot--high volcano that last erupted in l999.Visitors must carry their boards during the half-hour climb to the top. There,they go straight down the slope and sometimes they have to use their feet for brakes.Along the way.The board fills with rocks and dust,making boarders almost blind.Crashes are common."l wiped out twice and ripped my pants."said Melinda Vorisek, a tourist from Miami."But I'd do it again." Another tourist added:"It was sheer terror. I was eating dirt.But how many people can say they've bombed down a volcano?" Question: Who is the key person to develop the sport of volcano boarding? - Anthony Alcalde - Darryn Webb - Cerro Negro - Melinda Vorisek
A: Darryn Webb

*Question*
Read the following article and select the best answer. Article: If you really want to go green, here's good news: eating green is good for you. The very foods with a high carbon cost---meat, pork, dairy products, processed snacks---also tend to be filled with fat and calories. A green diet would be mostly vegetables and fruits, whole grains, fish and lean meats like chicken---a diet that's eco- and waistline-friendly. Eating green can be healthier and beneficial to the climate. It may be hard to believe that a meal at McDonald's produces more carbon than your trip to a far away place. More than 37% of the world's land is used for agriculture, much of which was once forested. Deforestation is a major source of carbon. The fertilizer and machinery needed on a modern farm also have a large carbon footprint, as does the network of ships and trucks that brings the food from the farm to your plate. The most efficient way to reduce the carbon footprint of your menu is to eat less meat, especially beef. Raising cattle takes a lot more energy than growing the equivalent amount of grains, fruits or vegetables. What's more, the majority of cattle in the U.S. are fed on grain and loads of it---670 million tons in 2002---and the fertilizer used to feed that creates separate environmental problems. Focus on eating lower on the food chain, with more plants and fruits and less meat and dairy. It's simple. We can change today what goes into our bodies for the health of our planet and ourselves. Question: In the author's opinion, the most efficient way to reduce carbon is to _ . - eat more vegetables than meat - stop raising the cattle - plant more grains - use less fertilizer
**Answer**
eat more vegetables than meat
