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

Computers are now an important part of human life. Without them, the modern world will stop: nobody will be able to travel, work, shop, watch TV, get money, or send messages.

However, together with computers come viruses - a kind of computer program. They move from one computer to another and damage the memory or other parts of the computer. Some viruses are difficult to stop; they can damage millions of computers in a very short time. The first virus called Brain appeared in 1986. In 1987, a more dangerous virus called Jerusalem appeared. It stayed in the computer and did nothing until the date was Friday 13th when it started to damage the computer's memory.

By the late 1990s, most computers were part of the e-mail and Internet systems. This meant virus programs could do a lot of destruction very quickly. The Melissa virus, for example, could move from one computer to another by e-mail - it automatically sent itself to every other email address in the address book.

In an effort to fight against viruses, programmers wrote antivirus software. Virus programmers are getting better all the time, but so is the antivirus software. However, a virus is always spread before a remedy takes action. People believe that one day a computer virus will bring the whole world to a stop for a few hours, which may paralyze many nations' government systems and cost the lives of many people who are traveling in a plane or undergoing an important operation.
