Read the following article and select the best answer. Article: Speeding off in a stolen car, the thief thinks he has got a great catch.But he is in for an unwelcome surprise.The car is fitted with a remote immobilizer, and a radio signal from a control centre miles away will ensure that once the thief switches the engine off, he will not be able to start it again. The idea goes like this.A control box fitted to the car contains a mini-cellphone, a micro-processor and memory, and a GPS satellite positioning receiver.If the car is stolen, a coded cellphone signal will tell the control centre to block the vehicle's engine management system and prevent the engine being restarted. In the UK, a set of technical fixes is already making life harder for car thieves." ," says Martyn Randall, a security expert.He says it would only take him a few minutes to teach a person how to steal a car, using a bare minimum of tools.But only if the car is more than 10 years old. Modern cars are far tougher to steal, as their engine management computer won't allow them to start unless they receive a unique ID code sent out by the ignition key.In the UK, technologies like this have helped achieve a 31% drop in vehicle-related crime since 1997. But determined criminals are still managing to find other ways to steal cars, often by getting hold of the owner's keys.And key theft is responsible for 40% of the thefts of vehicles fitted with a tracking system. If the car travels 100 metres without the driver confirming their ID, the system will send a signal to an operations centre that it has been stolen.The hundred metres minimum avoids false alarms due to inaccuracies in the GPS signal. Staff at the centre will then contact the owner to confirm that the car really is missing, and keep police informed of the vehicle's movements via the car's GPS unit. Question: The operations centre will first _ after receiving an alarm. - start the tracking system - contact the car owner - block the car engine - locate the missing car
contact the car owner

Q: Read the following article and select the best answer. Article: Japanese Students Suffer from Pressure Last April,15-year-old Rei Iwasaki stopped her piano and flute lessons and began to study every day of the week. Her parents paid to send her to a "cram school ."She wanted very much to pass her exams. In February she did pass an all-day, five-subject examination and entered the high school she hoped to enter. Thirteen-year-old Akio Yoshiwara wasn't so lucky. Unable to take the pressure of the exams, he hanged himself in February. He left a suicide note which said, "I did my best in this dear life, but it's no good." Suicides are now a common part of life among students in Japan. The cause is the incredible pressure of the "examination hell." Even a number of teachers are committing suicide each year. When some students broke windows in a school near Tokyo, the principal blamed himself and wrote the following note: "The incidents were due to the lack of appropriate measures by the principal and I apologize. I am very tired. The Japanese educational system is much different from the American system. It is perhaps the most regimented school system in any of the industrialized nations. Boys and girls wear uniforms and go to school six days a week --- 240 days a year compared to 180 in the U.S. Ninety- five percent graduate from high school compared to seventy-five percent in the U.S. Students don't ask questions in class but only listen respectfully to the teachers. And every few year's students are tested to see which school they will enter next. There is stiff competition for the "best" schools. The result is a well-informed, disciplined student, ideal for factory and company work and excellent at learning specialized skills. But there is little fun in education, little creativity and the incredible pressure of "examination hell." Question: Why did the principal kill himself? Because _ - He thought it was his fault that some students broke the windows. - He was very tired. - He couldn't stand the pressure of the "examination hell". - He blamed himself and wrote a note.
A: He thought it was his fault that some students broke the windows.
