A computer crash has occurred when a computer's central processing unit 'freezes up' and cannot respond to further commands or perform additional functions. In the split second during a computer crash, however, certain functions are still possible. When cindy's micron 401 computer crashed, she suspected it was due to an electrical power surge to the computer. The micron 401 computer usually does not work fast enough during a crash to produce an error message on the screen before the computer 'freezes'. However an error message can be triggered by an electrical power surge to the computer. Whenever a micron 401 computer crashes without producing an error message on the screen, the computer's hard drive is damaged. Upon restarting her computer, cindy determined its hard drive was not damaged.

Which one of the following must be true on basis of the information above ?

(A) If the micron 401's processor worked faster during the crash, the computer 's hard drive would have been damaged.

(B) The micron 401's hard drive is specially suited to withstand computer crashes.

(c) If the the micron 401's crash was not due to an electrical power surge, the computer's processor worked unusually fast during the crash.

(D) The micron 401 computer is built to withstand electrical power surges.

(E) If an error message appeared on the screen of the micron 401, it did so only after computer crashed.


What analogy can we employ for us to arrive at the correct answer? why do you think option E is the appropriate answer to this question.
