Passage 12 The Thinking Machine turned to the worried businessman,“State(陈述) your problem.” “It isn’t a crime-that is, a crime that can be punished by law,” Mr. Grayson said, “but it has cost me millions, perhaps as much as ten million dollars! Briefly, there is an information leak at my office. My business plans have become known to others almost as soon as I have made them. My plans are large; I have millions of dollars at stake(赌金), and the need for secrecy is great. For years my plans have been safe, but half a dozen times in the last eight weeks they have become known to my competitors-in the smallest detail, and in time for them to steal my customers.”“Tell me more please,” said The Thinking Machine.“I make machines and tools used in factories. Recently I sent my salesmen(推销员) to a new Industrial area out West to demonstrate(展示) some new machines. At first this was a great success; the factory owners truly liked this on-the-spot service(现场服务) and bought everything the salesmen demonstrated.”“But suddenly my staff(员工) there reported that wherever they went, they were too late. My biggest business competitor had already sent their salesmen out to demonstrate their products at a lower price!”The Thinking Machine walked to the window. “So now you want to know how-and when-information is leaking from your office. Well, to whom do you tell your business plans?”“No one, except my personal secretary, Evelyn Winthrop. She has been with me for six years; more than five years before this leak began. I have always trusted her.”“And she is the only one who knows your plans?”“Well, she hears of my plans only a few minutes or so before I give orders to carry them out. This week, for instance(举例), I planned to send salesmen to Oklahoma with new oil drills(钻头). My district manager didn’t know this plan. Miss Winthrop heard of it only on the morning they were to go out. Then I dictated(口授) to her in my office some letters of instructions(说明书) to my district managers. That is all Miss Winthrop knew of my Oklahoma plan.”“You outlined(概述) the plan in those letters?” “No. They merely(仅仅) told my managers which salesmen I wanted for Oklahoma and the costs of the various(各种) drills.” “But a careful person, knowing the content of all those letters, could have worked out what you intended to do?” “Yes, but no one person knew the contents of all the letters. Miss Winthrop and I were the only tow human beings who knew what was in them all. Neither Miss Winthrop nor I left the office all day. Yet before the day ended, I received phone calls from two managers telling me of the unbeatable(竞争不过) offers(出价) from my competitor.” “What is your business competitor’s name?” “Ralph Matthews,” said Mr. Grayson. The Thinking Machine went to a desk, addressed an envelope(信封)，got a sheet(一张) of paper and placed it inside, and sealed(密封) the envelope. Then he turned back to Mr. Grayson, “let us go to see Miss Winthrop now,”he said.Who knew the contents of Mr. Grayson's letter?
A、Everyone in his company.
B、Only himself.
C、He and his female secretary.
