Read the following article and select the best answer. Article: It's exciting to imagine how future humans will have solved the problems we have now, or what amazing new inventions will make our lives more convenient and interesting. We asked top scientists to share their predictions on what the world will be like in a century. If they're right, the 2114 is going to be really cool. 1. Robots will do your chores and more Robots will be doing most of our jobs, from building homes to teaching math. There are already robots that clean floors and pump gas. In the future they will be more complicated and useful. Unfortunately, with robots taking all the jobs, unemployment will be high. 2. You will read minds. Speaking of being social, we will communicate in an entirely different way. Forget texts and emails. Mind-reading technology will allow us to send thoughts to each other without speaking a word. We will also be able to send thoughts to objects around us. (Instead of pressing "start" on the microwave, you could just think "start.") Meanwhile, chips implanted(in our brains will improve memory and intelligence. 3. Your car will drive you Today, around 30,000 Americans die in car accidents each year. One hundred years form now, accidents will be a thing of the past. According to Mark Safford, consultant or the U.S. Department of Transportation, future cars will drive themselves. These electric cars will communicate with other cars on the road to travel safely in close formation at high speeds. 4. You will eat fake meat. Raising animals is not an efficient way to produce food, and it harms the environment: Cows, chickens, and pigs eat a lot, and then we have to deal with all that poop(. What's more, that poop can up poisoning lakes, rivers, and streams. Today, scientists can "grow" meat in a lab from animal cells, but it's expensive and not very delicious. In the future, they will have perfected the process. You'll order hamburgers that come from factories, not cows. Scientists may even find ways to make lab-grown meat tastier and healthier than the real thing. Question: Future meat will be _ . - much more affordable - less tasty but healthier - more organic and delicious - more environmentally friendly
more environmentally friendly

Read the following article and select the best answer. Article: He Made It! One Sunday, Gavin, a teenager, went skiing at Sugarloaf Mountain in Maine. In the early afternoon, when he was planning to go home, a fierce snowstorm swept into the area. Unable to see far, he accidentally turned off the path. Before he knew it, Gavin was lost, all alone! He didn't have food, water, a phone, or other supplies. He was getting colder by the minute. Gavin had no idea where he was. He tried not to panic. He thought about all of the survival shows he had watched on TV. It was time to put the tips he had learned to use. He decided to stop skiing. There was a better chance of someone finding him if he stayed put. The first thing he did was to find shelter from the freezing wind and snow. If he didn't, his body temperature would get very low, which could quickly kill him. Using his skis, Gavin built a snow cave. He gathered a huge mass of snow and dug out a hole in the middle. Then he piled branches on top of himself, like a blanket, to stay as warm as he could. By that evening, Gavin was really hungry. He ate snow and drank water from a nearby stream so that his body wouldn't lose too much water. Not knowing how much longer he could last, Gavin did the only thing he could -- he huddled in his cave and slept. The next day, Gavin went out to look for help, but he couldn't find anyone. He followed his tracks and returned to the snow cave, because without shelter, he could die that night. On Tuesday, Gavin went out again to find help. He had walked for about a mile when a volunteer searcher found him. After two days stuck in the snow, Gavin was saved. Gavin might not have survived this snowstorm had it not been for TV. He had often watched Grylls' survival show Man vs. Wild. That's where he learned the tips that saved his life. In each episode of Man vs. Wild, Grylls is abandoned in a wild area and has to find his way out. When Grylls heard about Gavin's amazing deeds, he was super impressed that Gavin had made it since he knew better than anyone how hard Gavin had to work to stay alive. Question: What happened to Gavin one Sunday afternoon? - He hurt his eyes - He caught a cold. - He got lost. - He broke his skis.
He got lost.

Read the following article and select the best answer. Article: People around the world drink about 180 billion liters of soda a year. That translates to more than 29 liters per person. Experts say the amount of carbonated soft drinks we consume is growing. New research from the American Heart Association finds that drinking soda, even diet soda, may significantly increase your risk for heart disease. Dr. Ramachandran Vasan led the study. "Drinking just one or more sodas a day may not be as innocuous as people think." In a large study of 9,000 people, doctors discovered that those who drank one or more sodas a day had a 30% increased risk for obesity , a 25% increase in the risk for abnormal blood sugar levels, and a 32% increase in the odds of having low levels of good cholesterol . All of these factors increase the risk for heart disease. And there was no difference in the results for those who drank diet soda over regular soda. It's something that surprised even the researchers. Critics of the study say diet soda may not be the cause of increased risk of heart disease. Connie Diekman is president of the American Dietetic Association. "It does not conclusively say that this will cause that." In other words, it could be that unhealthy people like soda. Dr. Vasan found those who drink soda generally tend to have greater caloric intake. They eat more saturated fat and trans fats. They also eat less fiber and exercise less. Diet soda drinkers may also share this unhealthy lifestyle. Dr. Vasan agrees that the link he found between heart disease risk and diet soda needs additional study. Question: What can be inferred from the passage above? - All the experts agree with the results of the study. - Sodas of any kind are certain to increase the risk for heart disease. - People have expected the results of the research. - More studies are needed to prove the results.
(Answer)
More studies are needed to prove the results.
