Article: People are being lured onto Facebook with the promise of a fun, free service without realizing they're paying for it by giving up large amounts of personal information. Facebook then attempts to make money by selling their data to advertisers that want to send targeted messages. Most Facebook users don't realize this is happening. Even if they know what the company is up to, they still have no idea what they're paying for Facebook because people don't really know what their personal data is worth. The biggest problem, however, is that the company keeps changing the rules. Early on, you keep everything private. That was the great thing about facebook--you could create your own little private network. Last year, the company changed its privacy rules so that many things-- your city, your photo, your friends' names--were set, by default to be shared with everyone on the Internet. According to Facebook's vice-president Elliot Schrage, the company is simply making changes to improve its service, and if people don't share information, they have a "less satisfying experience". Some critics think this is more about Facebook looking to make more money. Its original business model, which involved selling ads and putting them at the side of the page, totally failed. Who wants to look at ads when they're online connecting with their friends? The privacy issue has already landed Facebook in hot water in Washington. In April. Senator Charles Schumer called on Facebook to change its privacy policy. He also urged the Federal Trade Commission to set guidelines for social-networking sites."I think the senator rightly communicated that we had not been clear about what the new products were and how people could choose to use them or not to use them," Schrage admits. I suspect that whatever Facebook has done so far to invade our privacy, it's only the beginning, which is why I'm considering deactivating my account. Facebook is a handy site, but I'm upset by the idea that my information is in the hands of people I don't know.... Question: What does the author say about most Facebook users? Options: A: They are reluctant to give up their personal information. B: They don't know their personal data enriches Facebook. C: They don't identify themselves when using the website. D: They care very little about their personal information.

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: Ray Kurzweil is _ . Options: A: a famous medical scientist B: a computer research scientist C: a patient with Parkinson's D: an inventor of computer chips

Q: Read the article and select the best answer. Article: In cities with rent control, the city government sets the maximum rent that a landlord can charge for an apartment. Supporters of rent control argue that it protects people who are living in apartment. Their rent cannot increase; therefore, they are not in danger of losing their homes. However, the critics say that after a long time, rent control may have negative effects. Landlords know that they cannot increase their profits. Therefore, they invest in other businesses where they can increase their profits. They do not invest in new buildings which would also be rent-controlled. As a result, new apartments are not built. Many people who need apartments cannot find any. According to the critics, the end result of rent control is a shortage of apartments in the city. Some experts argue that the minimum wage law can cause problems in the same way. The federal government sets the minimum that an employer must pay workers. The minimum helps people who generally look for unskilled, low-paying jobs. However, if the minimum is high, employers may hire fewer workers. They will replace workers with machinery. Therefore, other things being equal, the number of workers that employers want decreases. Thus, critics hold the opinion that an increase in the minimum wage may cause unemployment. Some poor people may find themselves without jobs instead of with jobs at the minimum wage. Supporters of the minimum wage say that it helps people keep their dignity. Because of the law, workers cannot sell their services for less than the minimum. Furthermore, employers cannot force workers to accept jobs at unfair wages. Economic theory predicts the results of economic decision, such as decisions about farm production, rent control, and the minimum wage. The predictions may be corrected only if "other things are equal". Economists do not agree on some of the predictions. They also do not agree on the value of different decisions. Some economists support a particular decision while others criticize it. Economists do agree,... Question: The passage tells us about _ . Options: A: the relationship between supply and demand. B: the possible results of government controls. C: the necessity of government control. D: the urgency of getting rid of government control.
A: B
