If 9 trees are originally planted in a circular pattern as shown above, what is the least number of trees that must be transplanted so that the 9 trees will be in 2 straight rows?
选项
A、4
B、5
C、6
D、7
E、8
答案
B
解析
若9棵树最初以如左图所示的圆形种植,要使9棵树排在两条直线上,问最少需移植几棵树?
解:本题的正确答案为(B)。圆上的任意三点都不在同一条直线上,又根据在同一平面内的两点确定一条直线可知,要使这9棵树排在两条直线上,则至少得有9-2×2=5棵树被移植。
