Xerography

For a long time Chester Carison carried around his the invention,the little black box,over which he had worked and struggled for years.He presented it to the directors of twenty-one large American corporations,such as"General Electric,International Business Machines(IBM),Lockheed,and RCA."Nobody wanted it.
Nobody wanted to invest a penny in it.
It must be painful for those directors to think of Chester Carlson now. For the little black box is the heart of the multi-billion-dollar Xerox Corporation. Carlson is the inventor of "xerography（静电复印术）"(from two Greek words meaning "dry writing"),the dry-printing process used in thousands and thousands of offices,businesses,industries,universities,shops,and government agencies around the world.
Thanks to Carlson,it now takes minutes to copy a document which,twenty years ago,would have kept a secretary busy for a whole day.And for a few pennies anyone can have a copy of anything from cooking recipes to Greek poetry.More than thirty billion such copies are made each year.
When Chester Carlson went to work in a patent office in 1930,the copying methods were slow, dirty,and expensive.In his job,Carlson had to make many copies of patents for inventions.One night,after working late and painfully,he decided that somebody had better find an easier way to do it. He went to work in the kitchen of his apartment with measuring cups and cooking pots.By 1937, having developed a simple form of xerography,he applied for his first patent on the process.
Then began Carlson's famous unsuccessful search for investors.Only in 1944,did the Battelle Memorial Institute of Columbus agreed to lent$3,000 to Carlson for research on his invention.According to the agreement,Carlson was to receive 25%of all profits.This part of the agreement later brought millions of dollars to Carlson,who borrowed money from his family to repay his debt.
Even with Battle's help,it took another year to find a company willing to buy Carlson's process. In 1945,Dr. Dessauser,director of the Haloind company,decided to adopt and market the process, which was then named"Xerox".Three years later,the Haloind company changed name to the Xerox company,which now is the 39^th largest company in the United States,with sales of over four billion dollars a year.

Why did Chester Carlson carry around his little black box for a long time?
A:Because no corporation wanted to invest money in it.
B:Because his invention looked too ordinary.
C:Because he was afraid that his invention might be stolen.
D:Because he had nowhere to place it.
