Article: When I first got an e-mail account ten years ago, I received communications only from family, friends, and colleagues. Now it seems that every time I check my e-mail,I have an endless series of advertisements and other _ that do not interest me at all. If we want e-mail to continue to be useful, we need specific laws that make spamming a crime. If lawmakers do not do something soon to prohibit spam, the problem will certainly get much worse. Computer programs allow spammers to send hundreds of millions of e-mails almost instantly. As more and more advertisers turn to spam to sell their products,individual e-mail boxes are often flooded with spam e-mails. Would people continue to use e-mail if they had to deal with an annoying amount of spam each time? This problem is troubling individuals and companies as well. Many spam e-mails contain computer viruses that can shut down the entire network of a company. Companies rely on e-mail for their employees to communicate with each other. Spam frequently causes failures in their local communications networks, and their employees are thus unable to communicate effectively. Such a situation results in a loss of productivity and requires companies to repeatedly repair their networks. These computer problems raise production costs of companies, which are, in the end, passed on to the consumer. For these reasons, I believe that lawmakers need to legislate against spare. Spammers should be fined, and perhaps sent to prison if they continue to disturb people. E-mail is a tool which helps people all over the world to communicate conveniently, but spam is destroying this convenience.
Question: According to the text, what is the major cause of the flooding spam?
Options: (A) Companies rely on e-mail for communications. (B) More people in the world communicate by e-mail. (C) Many computer viruses contain spam e-mail. (D) More advertisers begin to promote sales through spam.

Article: Although the weathermen's forecasts for a month ahead are only little better than guesswork, they are now making long-term forecasts into the next century with growing confidence. For the main trend (, ) in the world's climate in the coming years will, scientists say, be a predictable result of man's activities. At the start of the industrial revolution nearly two centuries ago, man set off a big experiment in planetary engineering. Unaware of what he was doing, he spared no thought for the consequences .Today the possible outcome is alarmingly clear, but the experiment is unstoppable. Within the lifetimes of many of us, the Earth may become warmer than it has been for a thousand years. By the middle of this century it may be warmer than it has been since before the last Ice Age. A warmer climate may seem welcome, but _ could bring many dangers, damages to crops in the world's main food-producing areas, famine , economic instability , civil unrest and even war. In the much longer term, melting of the great ice-caps of Greenland and Antarctica could raise sea-levels throughout the world. The average sea-level has already risen a foot since the turn of the last century, and if the ice-caps disappear completely, it would rise by nearly 200 feet. Complete melting might take many centuries, but even a small increase in sea-level would threaten low-lying parts of the world such as the Netherlands.
Question: Long-term weather forecasts beyond the year 2050 may seem strange because _ .
Options: (A) none of us will be alive then (B) weathermen cannot even forecast next month's weather correctly (C) weathermen can forecast much better than they used to (D) no one can stop engineering experiments
