Q: Which of these animals can move at the fastest speed? 下列何种动物可以用最快的速度移动呢？
(A) A cheetah. (猎豹)
(B) A peregrine falcon. (游隼)
(C) A sailfish. (旗鱼)
A: You really soar above the rest if you dove for B. This large, flying hunter gets a little help from gravity to win this contest. The falcon dives down at speeds up to 325 kilometers per hour to catch its prey. Of course, the cheetah and the sailfish are no slowpokes, as they are each the speed king of their environment. Cheetahs frequently run at 110 km/h. Sailfish rule the blue ocean and, believe it or not, can swim through the water just as fast as cheetahs go on land.
如果你选择了B，那么你确实高人一等。这种大型的空中狩猎者凭借一些地心引力的帮助赢得这场比赛。游隼能以时速325公里的高速向下俯冲以抓取猎物。当然，猎豹跟旗鱼都在各自生活环境中以速度称王，所以牠们也都不是慢郎中。猎豹常以每小时110公里的速度奔跑。旗鱼则是湛蓝海洋中的霸主－信不信由你，牠在水中游的速度与猎豹在陆地上奔跑一样快。
Q: What is the coldest temperature possible? 下列哪种温度是最低温呢？
(A) 0。C.
(B) -129。C.
(C) -273。C.
A: If you picked C, then you’re a cool customer. In fact, -273。C is known as “absolute zero,” and according to physicists, something at that temperature has no thermal energy. It is well-known that water freezes at 0。C, and -129。C is the coldest natural temperature on Earth. Although scientists have created very low temperatures in experiments, they have never achieved absolute zero.
如果你选了C，那你一定是位「冷」静的人。事实上，零下273度称为「绝对零度」，而根据物理学家的说法，在此温度下的某物是没有热能的。众所皆知，水结冰的温度为零度，而地球上的自然低温为零下129度。虽然科学家们在实验中已经成功创造出极低的温度，他们仍无法实现绝对零度。

Q: Bears have one very powerful sense, but which is it? 熊有非常敏锐的感官，是哪种感官呢？
(A) Smell. 嗅觉
(B) Sight. 视觉
(C) Sound. 听觉
A: You have a nose for animal trivia if you picked A. Then again, your nose is still nothing compared to a bear’s. Their noses are seven times more sensitive than a bloodhound’s, let alone a human’s. Bears can sniff a river to find fish, or even detect a bleeding animal from dozens of kilometers away. This powerful ability makes it important for campers not to leave out any yummy snacks for bears to come and find.
如果你选A，任何有关动物的大小事都逃不过你的法「鼻」。不过话说回来，你的鼻子还是无法与熊相比。熊的嗅觉比猎犬灵敏七倍，更别提人类了。熊能嗅出河流的位置以便捕鱼，也能从数公里远处外发现受伤流血的动物。因为熊有如此敏锐的嗅觉，露营者要避免留下美味的点心将熊引来。
Q: Several animals can live longer than humans. Which animal can live the longest? 有些动物能比人类更长寿。哪种动物是最长寿的呢？
(A) A bowhead whale. (弓头鲸)
(B) A koi fish. (锦鲤)
(C) A jellyfish. (水母)
A: Swimming must be the secret to a long life, because all three of these choices live in the sea. However, it is a type of jellyfish, known as the “immortal jellyfish,” which outlasts the rest. While koi and bowhead can live up to two hundred years, we aren’t really sure how long the immortal jellyfish can live. It can become a mature adult, then go back to its immature stage, and repeat the process again and again. This curious animal may have found the fountain of youth.
在水中悠游一定是长寿的诀窍，因为以上三个选项的生物都是生活在水中，而被称作「永生水母」的水母则是其中最长寿的。虽然锦鲤和弓头鲸可以活到两百岁，但我们却不能确定永生水母可以活多久。这种水母在成熟后又会回到年轻的阶段，并不断地重复这样的过程。这种奇妙的动物或许是找到了青春之泉。
