问题 Which of the following is NOT one of the advantages of mini-computers?
If all linear dimensions of a computer is scaled down to one tenth, ______.

选项 A、the speed of its operation will go up ten times
B、the electric signals will go to and fro ten times faster
C、its operation speed will remain constant
D、its weight will be reduced to one tenth

答案A

解析 根据第二段第5句…scaling down of all linear dimensions in the ratio of one to ten also gives a valuable bonus:the speed of operation is scaled up 10 times.可知,电脑的运算速度将提高到原来的10倍,只有答案选项符合此意。
