[单选题]Passage FiveA young girl and a man were recently found murdered in a parked car in a Boston suburb. The police found no clue (线索) in the car. Then they found a witness who had seen a car pass by the murdered couple's car. He said it was a 1950 or 1951 Chevrolet (雪佛莱牌汽车).
A. Ordinarily, searching through the files for owners of elderly Chevies would have been an impossibly difficult task because there were two and a half million such cars. In this case, however, the police had a powerful tool--the computer.
B. The Boston Registry of Motor Vehicles programmed its computer to screen all 1950 and 1951 Chevrolets within a fifteen-mile radius (半径) of the suburb--the area in which the police believed the murderer was most likely to be found. Within minutes, the computer uncovered one thousand of the wanted cars. A few hours of careful hand screening turned up a 1950 Chevrolet owner who lived close to the scene of the crime and who had received many traffic tickets (交通罚款). He was among the first suspects to be investigated, and evidence linking him to the murdered couple was found. He was arrested, and is now waiting for trial (审判).
C. 51. The computer DIDN'T help the police ______.
D. to find the suspect
E. to find the murdered couple
F. to arrest the suspect
G. to search a 1950 or 1951 Chevrolet
