Read the following article and select the best answer. Article: Scottish pupils recently were part of a new scheme that allowed them to take their exams online. Those examinations provided a glimpse of the future in May when 120 _ in 10 centers in Scotland sat in front of computers to take a multiple-choice online exam. Although candidates were using a computer mouse instead of a pen, in all other ways the exam was the same as normal. Exam rooms were set out to ensure that only the candidates and the teachers were able to see the individual screens. The online answers were sent directly to a safe area. According to the students at St Ninian's in East Renfrewshire who took an online French exam, it was definitely the most motivated they had ever felt when taking an exam. "I could go as fast as I wanted to, rather than as slow as everyone else wanted to," said one. "It was better than looking back and forth between the questions," said another. One pupil even described it as fun. Their head teacher, Dorothy Graham, was not so surprised, "They are so used to doing things on computers that it seems natural for them. The boys liked it because they didn't have to worry about how neat their work was." The only things that worried her were power cuts and systems' crashing. It's thought that online exams could be the norm in about five years. However, last year there were warnings about computerizing exams in England and Wales. It's thought that it could be unfair to some students if they come from homes without access to a computer. Question: Pupils who take this kind of exam _ . - do not need to write the answers down - must write the answers clearly with a mouse - have to answer the questions very quickly - can answer the questions for as long as they like
do not need to write the answers down

Q: Read the following article and select the best answer. Article: She almost did not run. Christine Williams admits that now. She could barely put one foot after another following the wake for her sister, who had died in an automobile accident. But she did run. With the cheers of friends and strangers reaching her heart, Williams set a C.W. Post record in Boston. Now she will run again, in the national Division II cross-country championships in Evansville, Ind. She wanted to be sure she was doing the right thing by running. She was the middle of three sisters, between Kerry, who is 25, and Jennifer, who was 18. Just going through any motions was hard enough, but Christine Williams wanted to know if she should put on her uniform and her shoes and run through the woods on an autumn afternoon, in the awful gaping time between her sister's wake and her funeral. "I kind of got upset beforehand." Williams admitted. Not a chatterbox under normal conditions, she now holds herself the best way she can, the fewer words the better. She almost walked away from the start line. But her friend Angela Toscano, who had flown up to Boston with her, directly from the wake, was standing near the line and talked her through it. "She said my sister would have wanted me to run." Christine said. And that was enough to get her started. The accident happened just after midnight on Nov, 4. Four young women were driving in an unfamiliar area of Long Island in Eastport, N.Y., when one of them apparently ran a yield sign, and the car was hit by another vehicle. Heather Brownrigg and Jennifer Williams died, and their friends April Brown and Kaci Moran were treated at a hospital and released. The crash made the papers. April Brown was charged with drunken driving and driving without a license. The wake began on Nov. 6. The next day Christine was to run with the Post cross-country team at the regional meet. Rich Degnan, the Post coach,"and Post officials offered a car service and tickets on the last flight-to Boston for Christine and Toscano. When they arrived at the hotel, the entire team was waiting up... Question: What is the crucial factor contributing to Christine's success in the race? - Diligent practice. - Excellent coaching. - Good relationships. - Firm determination.
A: Firm determination.

Read the following article and select the best answer. Article: Hi, I'm your tooth. I've been asked to represent the rest of your teeth. We need your help. We like to be clean when you show us off with your big, wide smiles. First, let me tell you a little about us. You weren't born with the baby teeth, they developed when you were about six or seven months old. You went from milk to real food in no time thanks to your twenty primary teeth. Eventually, they loosened and fell out, one at a time, probably about the time you were six or seven years old. Then we came into your life. We are your permanent teeth, all twenty-eight of us. Some people may even have thirty-two depending on those wisdom teeth in the back. Sometimes they are able to help, and sometimes they cause trouble. Many times wisdom teeth are sideways and have to be pulled. Some people don't even have them at all! On a more personal note, I am an incisor, and you have seven more just like me, here in the front of your mouth. We do the biting on those chocolate chip cookies you like so much. Next to us are the canines, four sharp teeth, two on either side. Their job is to tear food; pizza is a good one for them. Behind them are eight premolars and eight to twelve molars, depending on those wisdom teeth. The molars do the majority of the work chewing the food that you eat. They do a great job on those carrots you like so much! Did you know we not only help you bite and chew but also help you talk? That's right. Try to say "tooth" without letting your tongue touch the back of your teeth. It sounds pretty funny, doesn't it? Question: How many teeth does a four-year-old boy usually have according to the passage? - 20. - 24. - 28. - 32.
(Answer)
20.
