there are two right internal angles;
there are five vertices;
【答案】B
【思路】五个顶点就表示有五个角,那么这个图形就是无边形,内角和为180=3180=540,其平均数为540/5=108。而条件一无法确定到底有几个角。

the items in A are even, the items in B is odd;
the sum of A is equal to sum of B;
【答案】E
【思路】举反例:A{-2,2} B{-1,1} OR A{2,4,6,8} B{1,3,5,11}
以上就是的详细内容,考生可针对文中介绍的方法进行有针对性的备考。最后预祝大家在GMAT考试中取得好成绩!
