求教破解版一ds ~~不转不转

请大家帮忙给看一下

Six countries in a certain region sent a total of 75 representatives to an international congress, and no two countries sent the same number of representatives.  Of the six countries, if Country A sent the second greatest number of representatives, did Country A send at least 10 representatives?

 

(1)  One of the six countries sent 41 representatives to the congress.

 

(2)  Country A sent fewer than 12 representatives to the congress.

(1) 75-41=34,如果A国送11个人去,其他四国可以是9,8,4,2

                        如果A国送9个人去,其他四国可以是8, 7, 6, 4

                        So, insufficient

(2) 验证方式同上

所以答案是E

谢谢connie4895 !! 只是我总是和那种““NO”也是充分的” 题混~~  这个题 我老觉得:如果1,那么a国 不是最少派10个。如果2,那么a国也不是最少派10个,所以选D。。。。
