课文讲解
Q: The Earth is home to more than seven billion people. But what would happen if everyone jumped at once? 地球上有超过70亿人口居住，倘若每个人同时跳跃会发生什么事呢？
(A) We would cause a powerful earthquake. 我们会导致强震发生
(B) We wouldn’t do much of anything. 我们无法产生多少影响
(C) We would stop the Earth’s rotation. 我们会让地球停止自转
A: If you said B, jump for joy because it’s the answer. The Earth is much too heavy to be affected by all its inhabitants jumping in unison. In fact, it would take seven million times more people than the current population all jumping together to produce an earthquake with the magnitude of Japan’s 2011 Tohoku earthquake. Surprisingly, the force of that earthquake changed the Earth’s spin enough to make every day 0.00000018 seconds shorter than before.
如果你选择B，欢跃而起吧！因为那正是答案。地球重到不足以被所有居民同时一跃而起而影响。事实上，如果要制造出与2011年日本东北大地震，还需要比现今地球多出700万倍的人口同时跳跃才办得到。但令人惊讶的是，该次地震的力道竟足以改变地球的自转速度，使每天较以往缩短了0.00000018秒。
Q: The first photograph was taken in 1826. But how many photos have been taken since then? 世界上第一张照片于1826年被拍下，而从那之后共有多少张照片被拍下呢？
(A) 900 million photographs 9亿张照片
(B) 250 billion photographs 2500亿张照片
(C) 3.5 trillion photographs 3.5兆张照片
A: You captured the right answer if you picked C. Since the invention of digital photography, the number of pictures taken has soared. A team of bloggers calculated the number by multiplying the average number of photos taken with a digital camera by the number of digital cameras owned. Then they added that number to all the film sold since 1826. The team also guesstimated we took four billion photos worldwide in 2012 alone.
如果你选C，你便捕捉到正确的答案了。自从数字摄影问世后，照片的数量大幅增加。一组部落客将一台数字相机平均的拍照数量和被拥有的数字相机数量相乘，再将计算出的数字加上自从1826年卖出的所有胶卷量。这组团队还估算出我们单是在2012年就拍了40亿张相片。

Q: We have two eyes so we can perceive depth, and we have two ears to help figure out which direction sounds originate from, but why do we have two nostrils? 我们拥有双眸以察觉深度，及一双耳朵以明白声音从何处而来，但为什么我们有一对鼻孔呢？
(A) So we can get twice the amount of oxygen. 如此我们才能吸进两倍的氧气量
(B) So we can smell more than one thing at a time. 如此我们才能一次闻不只一样东西
(C) So we can absorb different particles at different rates. 如此我们才能以不同的速度吸收不同的微粒
A: If you chose C, then you sniffed out the right answer. Throughout the day, our nostrils perform one of two tasks. One hole pulls in chemicals like oxygen quickly, because they’re needed right away, while the other brings in select particles slowly. The slower one does this because certain small matter takes longer to process. Our nostrils switch roles throughout the day. So, the functions of two nostrils can complement each other.
如果你选C，那么你就是嗅出正确答案了。一天当中，我们的鼻孔需要负责两项任务。其中一个鼻孔需要快速吸进如氧气等需要被实时吸收的化学物，同时另一个鼻孔则较缓慢地吸入挑选过的微粒，原因在于有些细小的物质需要较久的时间处理。我们的鼻孔在一天当中会互换角色，如此一来两个鼻孔便得以互补。
Q: You and I are looking at the same apple; I see red and you see red, but do we see the same red? 你和我正同时凝视着同一颗苹果。我看到红色，你也看到红色，但我们看到的是一样的红色吗？
(A) Yes, we would both see the exact same shade of red. 没错，我们见到的红色完全相同
(B) It’s impossible to tell whether we are seeing the sane color or not. 我们看到的颜色相同与否是无法辨认的
(C) My red is definitely darker than your version of red. 我看的红色绝对比你的红色要深
A: If answer B was the apple of your eye, then congratulations. Since you cannot take a look at the world through another person’s eyes, it’s impossible for you to know if you both see one color in the same way. Things which are experienced, but cannot possibly be explained to another (like your version of the color red) are called qualia. Scientists call this failure to explain these experiences the “explanatory gap.”
若答案B在你眼中最顺眼，那么恭喜你！有鉴于你不可能透过另一人的眼睛观看这个世界，要能分辨你们两人感知到的颜色是否一样是不可能的。能被感知但无法向他人解释的事物（例如你感知的红色），称为「感质」，而科学家将这种无法解释的现象称作「解释的鸿沟」。
