Another kind of challenge faced the Egyptians between 4,000 and 5,000 years ago when they decided to build the first pymp3id. They used six million tons of rock. That is enough to build a ten foot wall around all of France. Four hundred thousand men worked for twenty years to build it.

　　So, for thousands of years, people accepted challenges. Today we still have many challenges before us.

　　Passage Two

　　Today we’ll examine the role that private transportation — namely, the automobile — plays in city planning.

　　A number of sociologists blame the automobile for the decline of the downtown areas of major cities. In the 1950’s and 1960’s the automobile made it possible to work in the city and yet live in the suburbs many miles away. Shopping patterns changed; instead of going to downtown stores, people in the suburbs went to large shopping malls outside the city and closer to the home. Merchants in the city failed, and their stores closed.
