I end the race. I am the beginning of the end. The start of eternity and the end of space. There are two of me in Heaven and one in hell. I am in water, fire, sunshine and darkness. I am the beginning of earth and the end of life. What am I?
（答案为一个字母）
Of all my siblings, which I have many,
I am the number, wise old twenty.
I always wear, my long thin hat,
And stand on one leg, I've never sat.
I'm last of last, and last of first
I'm last of the best, and last of the worst.
Who am I?
（答案为一个英语字母）
I begin eternity and end space. At the end of time and in every place. Last in life, second to death. Never alone; found in your breath. Contained by earth, water or flame. My grandeur so awesome wind dare not tame. Not in your mind. Am in your dreams. Vacant to Kings, Present to Queens.
（答案为一个字母）
“我说这种你放弃不就好了?反正一你追不到她,二这种事我不能一帮再帮阿.”
“我说老曹看在我对你那么好,那么真诚的态度上就不能将就将就? 难道这种程度的题就难道你这个大侦探了?”
“别激我, 而且我破了这种题也没好处拿有什么用?”
在同样的咖啡厅里, 我们熟悉的曹探长又在“和平”的和他的老朋友崔志勇在喝咖啡聊天了. 这次崔志勇又有了新的麻烦. 他正在追一个读大二的mm，然后对方给了他一道迷题说是如果他解不出来就没资格追她。而那道题上有一副画着人来人往的街道上有一个人对人群正在做调查。然后画的下面就是迷题
_ _ _ i _ _
r _ _ _ _ _ _ h
“她说是两个英文单词来的，还说如果我连这种题也做不出来就不要混了。叫我再回去考英文。”
“这道题虽然有为难成分但如果你真的一点也做不出确实可以去重学英文了。”
说完曹探长写上了答案，崔志勇拿过来一看。
“天哪！ 原来这么简单！”
请问答案是什么？（提示：这是一个很简单的英文猜字游戏）
