Article: There are a lot of public libraries in Britain. These libraries have more than one hundred and fifteen million books, not including those libraries of public schools. Public libraries not only lend books, music records but also help children, patients in hospitals and others to get special play readings, film shows and so on. The first public libraries were founded in about the year 1850. Today's public libraries usually have a reading-room, a lending room and a reference room. The greatest and most famous library in Britain is that of the British Library in London. It was founded in 1973 and has over 10, 000, 000 books. It has nearly every magazine, newspaper and book published in Britain and other parts across the world. 
 Answer: 10,000,000 or less.
Solution: How many books are there in the British Library?
Why? In the Article, 10,000,000 is mentioned for the number of books available in the British Library, so this is a good question.

New input: Article: "Extra? Extra! Gasoline hits four dollars a gallon!"                 No one will really be shocked -- except, perhaps, the old-timers who tell about the good old days when gas was three gallons for a dollar, and people drove around "just for the fun of it". As a matter of fact, the price of gas has been rising fast and steadily for several years, and many adjustments have already been made.                  There was, for a time, considerable unemployment in the auto industry, and three quarters of the garages and service stations have gone out of business. However, the bicycle and motor-scooter business has flourished , and many people have found employment there. Now that Federal Motors has brought out its new Lilliput, which travels forty miles on a gallon, the auto business is picking up again. The factories that haven't switched over to two-wheel transportation are working on their new smaller models. There is talk, too, about bringing out new steam and electric automobiles that will be just as economical as the old cars. In the meantime, streetcars are gradually replacing buses all over the country because of the greater economy of electric power. And many people who have seldom used public transportation are now riding the streetcars while their automobiles rust in their garages. There's no market at all for their big, luxurious cars, for only the wealthy can now afford to operate them. Many people are now shopping in their own neighborhood, and small businesses are thriving.                  Ministers, educators, and editorial writers are pointing out that there has been a great improvement in family life. Families now stay at home more for their fun, and children and parents are becoming better acquainted. The stores report a booming business in parlor games, hobby materials, books, musical instruments and albums.                  People have lost their pale indoor look. The revival of the lost art of walking has brought a healthy pink back to many a cheek. This return to the heels has revolutionized the clothing styles; people now need to be ready for all kinds of weather.                  These conditions, however, may not last. Already our clever chemists are at work on new synthetic fuels which, they say, will put us right back where we were -- on wheels. Shall we wish them success or not? 
 Answer: People shop in nearby stores without having to drive, so small businesses are declining.
Solution:
Which of the following is NOT a result of the gas price rising?
