最近，國外社交網站上一道題目火了，難倒了一眾歪果仁，火爆程度不亞於當年「藍黑」的還是「白金」的裙子……
這道題江湖人稱「特蕾莎女兒之謎」，謎面其實很簡單，就是有點……繞……
來看題：
"If Teresa's daughter is my daughter's mother, what am I to Teresa?"
如果特蕾莎的女兒是我的女兒的媽媽，那我是特蕾莎的誰？
題目還給了5個選項：
a) Grandmother外婆
b) Mother媽媽
c) Daughter女兒
d) Granddaughter外孫女
e) I am Teresa.我是特蕾莎
對親屬關係本來就沒有分太清的國外網友都被繞暈了……
Kayla：我、媽媽和麥克三個人剛花了10分鐘來解這道「特蕾莎女兒之謎」。
Nick Soldan：如果特蕾莎的女兒是我女兒的媽媽，特蕾莎是我的什麼？真是個謎啊！解不開！求助！！！
特蕾莎是誰？！！
特蕾莎的女兒是誰？！！
特蕾莎女兒的媽媽又是誰？？？！！
大概覺得這道題太難，BuzzFeed給出了題目的解題關鍵……
我女兒的媽媽（my daughter's mother）……其實，就是我呀！
這樣一來，這道題就變成了：如果特蕾莎的女兒是我，那我是特蕾莎的什麼？（If Teresa's daughter is me, what am I to Teresa?）
顯而易見，這道題選C，女兒（daughter）。
你是不是也恍然大悟？
什麼？你說一道不過癮？雙語君（微信ID：Chinadaily_Mobile）精選了一套題，看看你能做對幾道？答案在圖片下面，沒讀完題不許偷看哦~~
幾個女兒
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.我有十個或者更多女兒。
b.我有少於十個女兒。
c.我至少有一個女兒。
如果三個陳述中只有一個是真的，那麼我有多少個女兒？
答案：
I do not have any daughters and the true statement is: I have less than ten daughters.
我沒有女兒。唯一真實的陳述是：我有少於十個女兒。
因為如果我有女兒，那麼就一定有兩個陳述為真，因此，答案是我沒有女兒。
