Clifford Stoll ran a computer system in Berkeley, California. As a system administrator, he kept a close eye on the records. One day, Stoll found something strange in the payment record. There was a 75 cents mistake. One of the thousands of users had used the system for 75 cents worth of time and not paid for it.
It might sound like very little money to worry about. But that 75 cents was the first clue Stoll had to a much bigger problem--that a hacker had broken into Stoll' s computer system.

The problem can be particularly severe in a deprived home, a one-parent family for example, where there is little stimulation for children anyway.
Such children, while capable of mutual comprehension in a private language, often remain in comprehensible to outsiders and thus at a severe educational disadvantage. The only solution to the problem, cruel though it may seem, is to separate the twins thus forcing them to acquire ordinary speech helped and guided by sympathetic parents and teachers.
Many people don' t know that ______.
