There are stories about two U.S . presidents，Andrew Jackson and Martin Van Buren，which attempt to explain the American English term OK.We don’t know if either story is true，but they are both interesting.

The first explanation is based on the fact that President Jackson had very little education.In fact，he had difficulty reading and writing.When important papers came to Jackson，he tried to read them and then had his assistants explain what they said.If he approved of a paper.he would write“all correct”on it.The problem was that he didn’t know how to spell.So what he really wrote was“ol korekt”.After a while，he shortened that term to“OK”.

The second explanation is based on the place where President Van Buren was born，Kinderhook，New York.Van Bnren’s friends organized a club to help him become President They caned the club the Old Kinderhook Club，and anyone who supported Van Buren was called“OK”.

Although the Unite d States covers so much land and the land produces far more food than the present population needs，its people are by now almost entirely an urban society Less than a tenth of the people are engaged in agriculture and forestry(林业)，and most of the rest live in or around towns，small and large.Here the traditional picture is changing：every small town may still be very like other small towns，and the typical small town may represent a widely accepted view of the country，but most Americans do not live in small towns any more.Half the population now lives in some thirty metropolitan areas(1arge cities with their suburbs、of more than a million people each—a larger proportion than in Germany or England，let alone France.The statistics(统计)of urban and rural population should be treated  with caution because so many people who live in areas classified as rural travel by car to work in a nearby town each day.As the rush to live out of town continues.rural areas within reach of towns are gradually filled with houses，so that it is hard to say at what moment a piece of country becomes a suburb But more and more the typical American lives in a metropolitan rather than a small town environment.

29.If now America has 250 million people.how many of them are engaged in agriculture and      forestry?

A.About 25 million.            B.More than 25 million.

C.Less than 25 million.          D. Less than 225 million
