OG-12 DS-86求教~~~

Rainbeauty

86 A number of people each wrote down one of the first 30 positive integers. Were any of the integers written down by more than one of the people?

这个题目也没太看懂，它的逻辑，希望NN解释一下，谢谢~~
我对着提也很confused~~~‘Were any of the integers written down by more than one of the people?
'是不是应该理解为“任何一个整数都不止被一个人写过”？（于是选E。。。）而非OG上面解释的是 at least onr integer had to be written down by more than one person.？（答案是选A）
求解释：为什么不能按照我的那个理解“任何一个整数都不止被一个人写过”？

任何一个整数都不止被一个人写过 = Were all the intergers written by more than one of the people?

Were any of the integers written down by more than one of the people? = Is there any number that was written down by more than one of the people?
