Read the following article and select the best answer. Article: A robot is a computer-controlled machine that is programmed to move and handle objects. Robots are able to perform repetitive tasks more quickly, cheaply, and accurately than humans. In 1995, about 700,000 robots were used-including over 500,000 in Japan, about 120,000 in Western Europe, and about 60,000 in the United States-all in the industrialized world. Many robots applications are designed for tasks that are either dangerous or unpleasant for human beings. Now, robotic technology can be used in more and more fields. Experts say in the future robots will be able to make new highways, constructsteel frameworks of buildings, clean sewage , and such physical work. Besides, another possibility is the development of robotic technology in medical surgery operations. Perhaps the greatest changes in future robots will improve from their increasing ability to reason. The field of artificial intelligence is moving rapidly from university labs to practical application in industry, and machines of a new kind of robots are being developed, _ can perform something involved in the process of understanding and planning, such as the management of a battlefield. Even the control of a large factory will be performed by intelligent computers. And there might be a possibility that these computers can design and make robots of their own. Is there anything dangerous involved in this artificial intelligence progress then? Robot technology has been making people nervous ever since it was invented. Is it unreasonable to worry that robots will someday become too clever? Is it impossible that these human-like robots will start to think and plan for themselves? Will robots take over the world and force humans to give them energy to survive? Question: In 1995, about 700,000 robots were working in _ . - Japan - the United States - Western Europe - the industrialized world

Read the following article and select the best answer. Article: SAN FRANCISCO--A phone app in San Francisco gives information about open parking spots. City officials in San Francisco introduced the app to try to reduce traffic jams in the city, but some say it raises safety concerns. In this city, drivers searching for parking spots lead to 30 percent of all downtown jams, city officials think. Now San Francisco has found a solution--a phone app for spot-seekers that displays information about areas with available spaces. The system, introduced last month, relies on wireless sensors fixed in streets and city garages that can tell within seconds if a spot has opened up. Monique Soltani, a TV reporter, said she and her sister spent 25 minutes on Friday trying to park. "We were praying to the parking god that we'd find a spot," she said. "If we had the app, we would not have to pray to the parking god." But the system could come with serious consequences. Some people say that drivers searching for parking could end up focusing on their phones, not the road. "It could be really distracting ," said Daniel Simons, a professor of psychology at the University of Illinois. City officials acknowledge the potential problem. They are urging drivers to pull over before they use the city's iPhone app, or to do so before they leave home. Nathaniel Ford, executive director of the San Francisco Municipal Transportation Agency, said safety could actually improve if drivers quickly found a spot instead of circling and getting frustrated. San Francisco has put sensors into 7,000 parking spots and 12,250 spots in city garages. If spaces in an area open up, the sensors communicate wirelessly with computers that in turn make the information available to app users within a minute, said Mr. Ford, of the transportation agency. On the app, a map shows which blocks have lots of places (blue) and which are full (red). More than 12,000 people have downloaded San Francisco's app, which is available now only for the iPhone but which city officials say they hope to bring to all similar... Question: According to the text, San Francisco city officials _ . - don't consider the app distracting - advise drivers to park cars slowly - are aware of the app's disadvantages - believe more parking spots are needed
are aware of the app's disadvantages

Q: Read the following article and select the best answer. Article: Thanks for bringing me down here to the university last Sunday. Classes didn't start until Wednesday, so I had a few days to get adjusted. I'm signed up for five classes: zoology, calculus, English, and two history sections. It's a heavy load, but they are all courses that will count for my degree. The zoology class which meets at 8:00 every morning is going to be my hardest subject. The history class that I have in the morning is on Western Civilization; the one in the afternoon is on early prefix = st1 /United Stateshistory, our ancestors' life. Calculus which I have at noon every day looks like it's going to be easy. Besides zoology, the other class that's going to be hard is English, for you see, we have to do a composition a week. I like all of my classmates but one. There are four of us in our suite including two girls from Texas and a girl from Manitoba. Sally who is fromSan Antoniois great: I feel like I've known her all my life. I also really like Anne who is the girl fromManitoba. Heather the other girl fromTexasis kind of a pain, though; she's one of those types of people who never tell you what's bothering them and then get hostile. I don't know how to get along with her but I'll try my best to make friends with her. This I take as one other class I myself open. All in all, though, it looks like it's going to be a great year. I'll write again in a week or so. Question: Which subject does the author regard the most difficult? - History. - English. - Zoology. - Calculus.

I want to take this opportunity to thank you for the many miles you will travel and all of the hours you will contribute to help make this one of the best programs in the entire state. We have our staff members make a home visit before adding each person to the program and try to visit everyone at least once every year. That is hardly enough, and we depend on your contact a great deal! It is important that you report back when you do not get an answer to your knock on the door. The person inside may be hurt or ill.

Many of those we serve cannot afford magazines and enjoy reading. If someone is interested in getting books from the Abilene Public Library, let us know. We can sign them up for the Books on Wheels program. Call if you smell gas strongly when you deliver meals, or if someone needs a space heater, a blanket, or an electric fan. Please convey all needs to us, and we will try to see that they are met. Some of the elderly people who we offer our service may have cancers, liver diseases, AIDS, etc. If you do not want to deliver meals to the people with certain types of health problems, such as these, please let us know.
