Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.

Smart cards and mobile phones are becoming an increasingly popular way to make all sorts of payments. Even now, in Japan thousands of transactions, from paying rail tickets to picking up the groceries, take place every day with customers passing their handsets across a small flat-screen device. And predictions in the world of finance reckon that payments using mobile phones will have risen to more than $50 billion in the very near future.

What's the appeal of e-cash? Compared to cheques or credit cards, it offers the speed of cash, but more so. It takes just one tenth of a second to complete most transactions and as no change is required, errors in counting are eliminateD. Fraud and theft are also reduced and for the retailer, it reduces the cost of handling money. Sony's vision of having a chip embedded in computers, TVs and games consoles means that films, music and games can be paid for easily without having to input credit card details.

And what about the future of the banks? Within their grip on the market, banks and credit- card firms want to be in a position to collect most of the fees from the users of mobile and contactless-payment systems. But the new system could prove to be a "disruptive technology" as far as the banks are concerneD. If payments for a few coffees, a train ticket and a newspaper are made every day by a commuter with a mobile, this will not appear on their monthly credit card statements but on their mobile phone statements. And having spent fortunes on branding, credit-card companies and banks do not want to see other payment systems gaining popularity. It's too early to say whether banks will miss out and if so, by how much. However, quite a few American bankers are optimistiC. They feel there is reason to be suspicious of those who predict that high-street banks may be a thing of the past. They point out that Internet banking did not result in the closure of their high-street branches as was predicteD. On the contrary, more Americans than ever are using local branches. So, whether we'll become a totally cash-free society remains open to contention.

Why does the author mention "a small flat-screen device" in the first paragraph?

A. to criticize the e-cash system

B. to inform the e-cash system

C. to exemplify the e-cash system

D. to praise the e-cash system

Read the following passage on transport, and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 36 to 42.

    Millions of people are using cellphones today. In many places, it is actually considered unusual not to use one. In many countries, cellphones are very popular with young people. They find that the phones are more than a means of communication - having a mobile phone shows that they are cool and connected.

    The explosion in mobile phone use around the world has made some health professionals worried. Some doctors are concerned that in the future many people may suffer health problems from the use of mobile phones. In England, there has been a serious debate about this issue. Mobile phone companies are worried about the negative publicity of such ideas. They say that there is no proof that mobile phones are bad for your health.

    On the other hand, medical studies have shown changes in the brain cells of some people who use mobile phones. Signs of change in the tissues of the brain and head can be detected with modern scanning equipment. In one case, a traveling salesman had to retire at young age because of serious memory loss. He couldn't remember even simple tasks. He would often forget the name of his own son. This man used to talk on his mobile phone for about six hours a day, every day of his working week, for a couple of years. His family doctor blamed his mobile phone use, but his employer's doctor didn't agree.

    What is it that makes mobile phones potentially harmful? The answer is radiation. High-tech machines can detect very small amounts of radiation from mobile phones. Mobile phone companies agree that there is some radiation, but they say the amount is too small to worry about.

    As the discussion about their safety continues, it appears that it's best to use mobile phones less often. Use your regular phone if you want to talk for a long time. Use your mobile phone only when you really need it. Mobile phones can be very useful and convenient, especially in emergencies. In the future, mobile phones may have a warning label that says they are bad for your health. So for now, it's wise not to use your mobile phone too often.

The word "means" in the passage most closely means ______.

A. “meanings”

B. “expression”

C. “method”

D. “transmission”
