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: (PARIS) ----An English tourist who was highly praised for rescuing a three-year-old boy in Paris said he didn't think twice before diving into the freezing river. Tuesday's news said 25-year-old John Smith from England was the man who left the spot quickly after the rescue last Saturday. He lifted the little boy out of the water after he fell off the bank. He handed the child to his father, David Anderson, who had dived in after him. "I didn't think at all," John told the News. "It happened very fast. I reacted very fast." John, an engineer on vacation, was walking with his girlfriend along the pier when he saw something falling into the water. He thought it was a doll, but realized it was a child when he approached the river. Immediately, he took off his coat and jumped into the water. When he reached the child, he appeared lifeless, he said. Fortunately, when he was out of the water, he opened his eyes. Anderson said his son slipped off the bank when he was adjusting his camera. An ambulance came later for him, said John, who was handed dry clothes from onlookers. John caught a taxi with his girlfriend shortly after. The rescue happened on the day before he left for England. John said he didn't realize his story had greatly moved Paris until he was leaving the city the next morning. "I don't really think I'm a hero," said John. "Anyone would do the same thing."
Question: What is the probable reason why John was in Paris?
Options: (A) To meet his girlfriend. (B) To visit his parents. (C) To work as an engineer. (D) To spend his vacation.

Article: If the crust of the earth were not pretty solid ,it would be shaking about and moving up and down frequently. However,there are places in the rocks of the earth's crust where it isn't strongly held together--where faults exist. Along the faults,one rock might push against another with great force. The energy is changed to vibration in the rocks,so they begin to shake and we have an earthquake! The most famous one in North America was the San Francisco earthquake of 1906. Seven hundred people died and property damage amounted to about $425,000,000.The greatest destruction came from the fires that followed the quake. One of the most famous earthquakes in Europe took place in Lisbon,Portugal,in 1755.The city was destroyed and at least thirty thousand people were killed. In 1908,in Calabria and Sicily,a quake killed about seventy-five thousand people. In 1915,in central Italy,hundreds of towns and villages were damaged and thirty thousand people were killed. Two great earthquakes that caused great damage in Asia took place in Tokyo,Japan,and in Gansu Province in China. The Tokyo quake of 1923 killed more than one hundred thousand people and destroyed the city and the city of Yokohama,too. The Chinese quake in 1920 covered more than three hundred square miles and killed about two hundred thousand people.
