Article: Botany, the study of plants, plays a strange role in the history of human knowledge. For many thousands of years it was one field about which humans had little knowledge. It is impossible to know today just what our Stone Age Ancestors knew about plants, but from what we can observe of preindustrial societies that still exists, a detailed learning of plants and their properties must be very ancient. This is reasonable. Plants are the basis of the food pyramid for all living things, even for other plants. They have always been greatly important to the good of peoples, not only for food, but also for clothing, weapons, tools, medicines, housing, and a great many other purposes. Tribes living today in the woods of the Amazon recognize hundreds of plants and know many properties of each. To them botany, as such, has no name and is probably not even recognized as a special branch of knowledge at all. Unfortunately, the more industrialized we become the farther away we move from direct relation with plants, and the less clear our knowledge of botany grows. Yet everyone comes unconsciously on a surprising amount of botanical knowledge, and few people will fail to recognize a rose or an apple. When our New Stone Age ancestors, living in the Middle East about 10 000 years ago, discovered that certain grasses could be harvested and their seeds planted for richer production the next season, the first great step in a new connection of plants and humans was taken. Grains were discovered and from them flowed the _ of agriculture: planted crops. From then on, humans would increasingly take their living from the controlled production of a few plants, rather than getting a little here and a little there from many varieties that grew wild and the collected knowledge of tens of thousands of years of experience and close relations with plants in the wild would begin to disappear. Question: According to the passage, why has general knowledge of botany decreased? Yes or no, is the answer "Direct relation with a variety of plants has decreased."?
No

Article: The Internet began in the 1960s as a small network of academic and government computers primarily involved in research for the prefix = st1 /U.S.army. Originally limited to researchers at a handful of universities and government departments, the Internet has quickly become a worldwide network providing users with information on a range of subjects and allowing them to purchase goods directly from companies via computer. By 1999, 84 millionU.S.citizens had access to the Internet at home or work. More and more Americans arc paying bills, shopping, ordering airline tickets, and purchasing stocks via computer over the Internet. Internet banking is also becoming increasingly popular. With lower overhead costs in terms of staffing and office space, Internet banks are able to offer higher interest rates on deposits and charge lower rates on loans than traditional banks. "Brick and mortar" banks are increasingly offering online banking services via some special websites to enlarge their traditional services. At present, 14 percent of Internet households conduct their banking by means of the Internet, and the figure is expected to double during the next two or three years. Increasing commercial use of the Internet has heightened security and privacy concerns. With a credit card, an Internet user can order almost anything from an Internet site and have it delivered to their home or office. Companies doing business over the Internet need many security measures to protect credit card, bank account, and social security numbers from unauthorized access as they pass across the Internet. Any organization that connects its networks to the global Internet must carefully control the access point to ensure that out-siders cannot disturb the organization's internal networks or gain unauthorized access to the organization's computer systems and data. Question: Which commercial usage of the Internet does the author NOT refer to? Yes or no, is the answer "Applying for a credit card."?
No

Q: Article: Medical scientists are already putting computer chips directly into the brain to help people who have Parkinson's disease, but in what other ways might computer technology be able to help us? Ray Kurzweil is the author of the successful book The Age Of Intelligent Machines. He is also one of the world's best computer research scientists. He is researching the possibilities. Kurzweil gets computers to recognize voices. An example of this is Ramona, the _ hostess of Kurzweil's website, created by the computer, who is able to understand what you say. Visitors to the website can have their own conversations with her. Ramona also dances and sings. Kurzweil uses this technology to help people with physical problems. One of his ideas is a "seeing machine". This will be "like a friend that could describe what is going on around," he explains. Blind people will use a sensor which will probably be built into a pair of sunglasses. This machine will describe to the person everything it sees. Another idea, which is likely to help deaf people, is the "listening machine". This invention will recognize millions of words and understand any speaker. The listening machine will also be able to translate what it hears into other languages, so even people without hearing problems are likely to be interested in using it. But it is not just about helping people with physical problems. Looking further into future, Kurzweil sees a time when we will be able to store what we hear, see and think in a computer. This technology probably won't be ready for at least 50 years, but when it arrives, it means our minds will be able to live forever. Question: How can the "seeing machine" help blind people? Yes or no, is the answer "It can describe to them what it sees."?
A: No
