　　TEST FOR DEMENTIA下列有4个问题及一个加分题，你必须立刻回答，不能花时间慢慢想，让我们看看你有多聪明。
　　Ready? GO!!! (scroll down)准备好，向下卷！
　　
　　First Question:第一题
　　You are participating in a race. You overtake the second place person. What position are you in? 你参加赛跑，追过第2名，你是第几名？
　　
　　Answer: If you answered that you are first, then you are wrong! If you overtake the second place person, and you take their place, you are second!
　　解答：如果你的回答是第1名，你就错了！你如果追过第2名，你只是取代那人的位置，你是第2名。
　　
　　To answer the second question, don't take as much time as you took for the first question. 回答第2题，你不能使用与回答第1题相同的时间。
　　Second Question第二题:
　　If you are in a race, and you overtake the last person, then you are?
　　你参加赛跑，你追过最后一名，你是第几名？
　　
　　Answer: If you answered that you are second to last, then you are wrong again. Tell me, how can you overtake the LAST person?! You're not having a good time at this! Are you?
　　解答：如果你的回答是倒数第2名，你又错了！告诉我，你怎能追过最后一名？显然你并未乐在其中！
　　
　　Very tricky maths! Note: This must be done in your head only. Do NOT use paper and pencil or a calculator. Try it. 很诡异的算术！这只能在脑中盘算。不要使用纸与笔或计算器，试试看。
　　Third Question:第三题
　　Take 1000 and add 40 to it. Now add another 1000. Now add 30. Add another 1000. Now add 20. Now add another 1000. now add 10. What is the total?
　　以1000加上40，再加1000，再加30，再加1000，现在加上20，再加一次1000，现在加上10，总数是什么？
　　
　　Answer: Did you get 5000? The correct answer is actually 4100. Don't believe it? Check with your calculator!
　　解答：得到5000是吗？正确答案是4100，不要相信，用计算器查证吧！
　　
　　Today is definitely not your day. Maybe you will get the last question right?
　　今天对你铁定诸事不宜，或许最后一题你会答对？
　　Fourth Question:第四题

　　Mary的父亲有5个女儿，第1个女儿 Nana， 第2个女儿 Nene， 第3个女儿 Nini， 第4个女儿 Nono，第5个女儿的名字是什么？

　　解答：答案是Nunu吗？不！绝对不是，她的名字是Mary，请再读一次问题！
　　
　　Okay, now the bonus round. You can partially redeem yourself with this one!!!!!
　　好，现在是加分题。这题可稍稍解救﹙弥补﹚你！
　　Bonus Question加分题:
　　There is a mute person who wants to buy a toothbrush. By imitating the action of brushing one's teeth he successfully expresses himself to the shopkeeper and the purchase is done. Now if there is a blind man who wishes to buy a pair of sunglasses, how should he express himself?
　　一个哑巴想买牙刷，他模仿刷牙的动作，成功的向店主表达，也完成了购买。现在如果一个瞎子想买一副太阳眼镜，他要如何表达？
　　
　　Answer: He just has to open his mouth and ask. He's blind, not mute - so simple.
　　解答：他只要张开嘴问即可。他是瞎子，不是哑巴。就这么简单！
