When you visit London, one of the first things you will see is Big Ben, the famous clock which can be heard allover the world on the B.B.C. If the Houses of Parliament had not been burned down in 1834, the great clock would never have been erected.

Big Ben takes its name from Sir Benjamin Hall who was responsible for the making of the clock when the new Houses of Parliament were being built. It is not only of immense size, but is extremely accurate as well. Officials from Greenwich Observatory have the clock checked twice a day. On the B.B.C. you can hear the clock when it is actually striking because microphones are connected to the clock tower. Big Ben has rarely gone wrong. Once, however, it failed to give the correct time. A painter who had been working on the tower hung a pot of paint on one of the hands and slowed it down!

VII. Read the following passage and choose the best answers to each of the questions.

Quite a number of things have been done tohelp solve traffic problems in Singapore. For example, motorists must buy a special pass if they want to drive into the downtown business district. They can go into the business district only if they have the pass displayed on their windshield.

Another thing Singapore has done is to make it more difficult to buy cars. People have to apply for a certificate if they want to buy a car. And the number of certificates is limited. Not everyone can get one. There is also a high tax on cars, so it costs three or four times as much to buy a car in Singapore as it does in, say, the United States or Canada. The other thing Singapore has done is to build an excellent public transportation system. Their subway system is one of the best in the world. And there is also a very good taxi and bus system.

1/ In Singapore, drivers must have .................... to drive into the downtown business district.

a. a special I D card b. a special pass c. a driving certificate d. a driving lesson
