温哥华天空最近，国外社交网站上一道题目火了，难倒了一众歪果仁，火爆程度不亚于当年“蓝黑”的还是“白金”的裙子……
这道题江湖人称“特蕾莎女儿之谜”，谜面其实很简单，就是有点……绕……
来看题：
"If Teresa's daughter is my daughter's mother, what am I to Teresa?"
如果特蕾莎的女儿是我的女儿的妈妈，那我是特蕾莎的谁？
题目还给了5个选项：
a) Grandmother 外婆
b) Mother 妈妈
c) Daughter 女儿
d) Granddaughter 外孙女
e) I am Teresa. 我是特蕾莎
对亲属关系本来就没有分太清的国外网友都被绕晕了……
Kayla：我、妈妈和麦克三个人刚花了10分钟来解这道“特蕾莎女儿之谜”。
Nick Soldan：如果特蕾莎的女儿是我女儿的妈妈，特蕾莎是我的什么？真是个谜啊！解不开！求助！！！
特蕾莎是谁？！！
特蕾莎的女儿是谁？！！
特蕾莎女儿的妈妈又是谁？？？！！
大概觉得这道题太难，BuzzFeed给出了题目的解题关键……
我女儿的妈妈（my daughter's mother）……其实，就是我呀！
这样一来，这道题就变成了：如果特蕾莎的女儿是我，那我是特蕾莎的什么？（If Teresa's daughter is me, what am I to Teresa?）
显而易见，这道题选C，女儿（daughter）。
你是不是也恍然大悟？
什么？你说一道不过瘾？双语君（微信ID：Chinadaily_Mobile）精选了一套题，看看你能做对几道？答案在图片下面，没读完题不许偷看哦~~
几个女儿
a. I have ten or more daughters.
b. I have less than ten daughters.
c. I have at least one daughter.
If only one of these statements is true, how many daughters do I have?
a. 我有十个或者更多女儿。
b. 我有少于十个女儿。
c. 我至少有一个女儿。
如果三个陈述中只有一个是真的，那么我有多少个女儿？
答案：
I do not have any daughters and the true statement is: I have less than ten daughters.
我没有女儿。唯一真实的陈述是：我有少于十个女儿。
因为如果我有女儿，那么就一定有两个陈述为真，因此，答案是我没有女儿。
