I'm taking a test and have to guess the right answer to the question after the article. Article: Your glasses may someday replace your smartphone, and some New Yorkers are ready for the switch. Some in the city can't wait to try them on and use the maps and GPS that the futuristic eyewear is likely to include. "I'd use it if I were hanging out with friends at 3 a. m. and going to the bar and wanted to see what was open," said Walter Choo, 40, of Fort Greene. The smartphone-like glasses will likely come out this year and cost between $250 and $600, the Times said, possibly including a variation of augmented reality, a technology already available on smartphones and tablets that overlays information onto the screen about one's surroundings. So, for example, if you were walking down a street, indicators would _ showing you the nearest coffee shop or directions could be plotted out and come into view right on the sidewalk in front of you. "As far as a mainstream consumer product, this just isn't something anybody needs," said Sam Biddle, who writes for Gizmodo.com. "We're accustomed to having one thing in our pocket to do all these things," he added, "and the average consumer isn't gonna be able to afford another device that's hundreds and hundreds of dollars." Google publisher Seth Weintraub, who has been reporting on the smartphone-like glasses since late last year, said he is confident that this type of wearable device will eventually be as common as smartphones. "It's just like smartphones 10 years ago," Weintraub said. "A few people started getting emails on their phones, and people thought that was crazy. Same kind of thing. We see people bending their heads to look at their smartphones, and it's unnatural," he said. "There's gonna be improvements to that, and this is a step there. " Question: According to Sam Biddle, the smartphone-like glasses are _ . Options: A: necessary for teenagers B: attractive to New Yorkers C: available to people worldwide D: expensive for average consumers
(Answer)
D

I'm taking a test and have to guess the right answer to the question after the article. Article: A new study gives us the warning that about thirty percent of the world's people may not have enough water by the year 2025. A private American organization called Population Action International did the new study. It says more than three-hundred-thirty-five-million people lack enough water now. The people live in twenty-eight countries. Most of the countries are in Africa or the Middle East. P-A-I researcher Robert Engelman says by the year 2025, about three-thousand-million people may lack water. At least 18 more countries are expected to have severe water problems. The demand for water keeps increasing. Yet the amount of water on Earth stays the same. Mr. Engelman says the population in countries that lack water is growing faster than in other parts of the world. He says population growth in these countries will continue to increase. The report says lack of water in the future may result in several problems. It may increase health problems. Lack of water often means drinking waters not safe. Mr. Engelman says there are problems all over the world because of diseases, such as cholera, which are carried in water. Lack of water may also result in more international conflict. Countries may have to compete for water in the future. Some countries now get sixty percent of their fresh water from other countries. This is true of Egypt, the Netherlands, Cambodia, Syria, Sudan, and Iraq. And the report says lack of water would affect the ability of developing to improve their economies. This is because new industries often need a large amount of water when they are beginning. The Population Action International study gives several solutions to the water problem. One way, it says, is to find ways to use water for more than one purpose. Another way is to teach people to be careful not to waste water. A third way is to use less water of agriculture. The report also says long-term solutions to the water problem must include controls on population growth. It says countries cannot provide clean water unless they slow... Question: The best title of the passage would be _ . Options: A: World Conflict B: Diseases and Water C: World Water Shortage D: Population and Water

I'm taking a test and have to guess the right answer to the question after the article. Article: Researchers are placing robotic dogs in the homes of lonely old people to determine whether they can improve the quality of life for humans. Alan Beck, an expert in human-animal relationship, and Nancy Edwards, a professor of nursing, are leading the animal-assisted study concerning the influence of robotic dogs on old people's depression, physical activity, and life satisfaction. "No one will argue that an older person is better off being more active, challenged, or stimulated ," Edwards points out. "The problem is how we promote that, especially for those without friends or help. A robotic dog could be a solution." In the study, the robot, called AIBO, is placed for six weeks in the houses of some old people who live alone. Before placing AIBO in the home, researchers will collect baseline data for six weeks. These old people will keep a diary to note their feelings and activities before and after AIBO. Then, the researchers will review the data to determine if it has inspired any changes in the life of its owner. "I talk to him all the time, and he responds to my voice," says a seventy-year-old lady. "When I'm watching TV, he'll stay in my arms until he wants down. He has a mind of his own." The AIBOs respond to certain orders. The researchers say they have some advantages over live dogs, especially for old people. Often the elderly are disabled and cannot care for an animal by walking it or playing with it. A robotic dog removes exercise and feeding concerns. "At the beginning, it was believed that no one would relate to the robotic dog because it was metal and not furry," Beck says. "But it's amazing how quickly we have given up that belief." "Hopefully, down the road, these robotic pets could become a more valuable health helper. They will record their masters' blood pressure, oxygen levels, or heart rhythms. AIBOs may even one day have games that can help stimulate older people's minds." Question: The author seems to suggest that the future robotic dogs may _ . Options: A: keep old people active B: cure certain diseases C: change people's beliefs D: look more like real dogs
(Answer)
A
