“一切都是謎，一個謎的答案是另一個謎?！?

——拉爾夫·沃爾多·愛默生，《生化的準(zhǔn)則·幻覺》

After a massive storm tears through the Hex Archipelago, you find five grizzled survivors in the water.?

Shivering their timbers, they explain that they’re the former crew of the great pirate Greenbeard, who marooned them after they tried to mutiny.?

Each was bound up in a different spot on a small island, until the storm washed them out to sea.

In gratitude for saving them, they reveal a secret: the island they were on is also where Greenbeard has buried his treasure hoard.?

一場強(qiáng)烈的暴風(fēng)雨襲擊六角群島后，你在海上發(fā)現(xiàn)了 五名戰(zhàn)戰(zhàn)兢兢的生還者。

恐懼發(fā)抖的生還者說他們是綠胡子大海盜的前水手。他們因?yàn)榕炎兌环胖稹?/p>

他們每人原本被捆綁 在一座小島上的不同位置，后來暴雨來襲才被沖到海中。

為了報答你拯救他們， 他們向你揭示一個秘密：他們被捆綁的島嶼上 藏著綠胡子的寶藏。

But when the sailors try to describe the island, something seems off.

All agree it was flat and barren with no prominent features except for some trees.?

Yet each pirate claims they saw a different number of trees, ranging from two to six.?

The pirate who saw two trees says the treasure was buried right at his feet.

但是，當(dāng)水手嘗試描述該島嶼時， 每個人所給的描述卻不一。

每人都同意該島平坦而且荒蕪， 除了一些樹木就沒有其他明顯的特征。

但是每一位海盜卻說 他們看見不同數(shù)量的樹，數(shù)目從兩棵到六棵不等。

看到兩棵樹的海盜說 寶藏就藏在他的位置之下。

When you fly your hot air balloon over the area to investigate, you see hundreds of small islands, each with exactly six trees.?

The next storm will be here soon, so you’ll have to hurry and narrow your search.?

What does the island with Greenbeard’s treasure look like from the sky??

And where will the treasure be on that island? Pause here if you want to figure it out for yourself!

當(dāng)你升起熱氣球搜索該海域時，你看到上百座小島， 每座都有六棵樹。

下一場暴雨即將來襲，你必須把握時機(jī)，把搜索范圍縮小。

綠胡子寶藏所在的小島 的俯視圖是怎么樣的呢？

而且寶藏會在該島的什么位置呢？

It might seem like the pirates are delirious from dehydration. But that’s not what’s going on. Remember, each was confined to a separate point on the island, and no two of them could see the same number of trees. That means that for all but one pirate, something was blocking their view. And since there are no other features on the island, that something could only have been other trees.

答案：三秒

答案：兩秒

答案：一秒

那些海盜似乎因脫水而神志不清。

但事實(shí)并非如此。

記得，每一位海盜都 被綁在該島的某一位置，而且他們每位都看見不同數(shù)目的樹。

這表示他們當(dāng)中 只有一位的視野是不被阻擋的。

既然島上沒有其他特征，阻擋他們視野的只有島上其他的樹。

A pirate would see fewer trees when two or more fell along a straight line from their vantage point.?

So we need to find the island where five different pirates standing in different spots would each see a different number of trees.?

Virtually every island has a position from which you can see six trees.?

And on most islands there’s a position where 5 trees can be seen by standing in line with two of them.?

It turns out that the hardest locations to find are those with fewer visible trees precisely because they require more trees to line up with the viewer’s position.

從海盜的觀點(diǎn)來看， 如果兩棵或以上的樹排成直線，那位海盜可看見的樹 的數(shù)目就變少了。

所以我們想要找的島嶼必須當(dāng)五位海盜位于不同的位置時，每位所看到的樹的數(shù)目將會不一樣。

幾乎所有島嶼都有一個位置 是可以看到所有六棵樹的。

而且大多數(shù)島嶼也有個位置 是可以看到五棵樹的，尤其是其中兩棵排成一條線。

最難找到的則是可觀察的樹木 比較少的位置，原因是因?yàn)閺挠^察者的觀點(diǎn)， 這些位置需要更多的樹木排列成線。

So how can we see just two trees??

One way would be if all the trees were lined up in single file, such as on this island.?

Then, you could stand at the end of the line and see one, stand in the middle and see two, or stand anywhere else and see all six.?

But there’s no place from which you can see only three, four, or five, so one straight line of trees is out.

那么一個人怎么可以只看到兩棵樹呢？

其中一種排法是如果所有的樹 都排成一條線，跟這座小島的一樣。

這樣，如果你站在尾端， 就可看到一棵樹，站在中間就可看到兩棵，或站在任何其他位置看到六棵。

但是這種排法卻無法看到三棵、四棵、或五棵樹。所以所有樹木排成一條線是不可能的。

So what about two lines of trees??

So long as the lines aren’t parallel and they intersect over land, there’ll always be a position where the two lines converge from which you could see exactly two trees.?

And if they’re grouped two and four, or three and three, there are many arrangements in which you could also see three, four, five, and six trees.

如果所有的樹木排成兩排呢？

只要這兩排樹不是平行的， 而且它們的交叉點(diǎn)是在島上，總有個位置， 也就兩條線交匯的地方你是可以看到兩棵樹的。

如果排列是兩棵和四棵、或兩排各三棵、該島就有不同的位置能讓你看到三棵、四棵、五棵、或六棵樹。

Fortunately for us, there’s only one island in the archipelago with two non-parallel lines of trees, and it’ll be buried at the intersection of the two lines.?

You land on this island and dig up a chest containing a massive pile of tree seeds, ready for planting.

Was this treasure really worth all that trouble??

That’s a matter of perspective.

很幸運(yùn)的，群島上只有一座島有兩排樹是非平行的，寶藏就埋在這兩排樹的交叉點(diǎn)。

你在這座島上著陸，把箱子挖出來， 發(fā)現(xiàn)里面裝著一大堆樹種，隨時供播種使用。

這個寶藏值得你費(fèi)力搜尋嗎？

這要看你的觀點(diǎn)了。
