Can you solve the death race riddle

你能解決死亡競賽之謎嗎

The night before the Death Race across the Wastelands is set to begin, your uncle, the great inventor Slate Kanoli, got kidnapped by the ruthless No-Side gang.?

The only way to get him back is to race his Coil Runner against the gang yourself.?

Win and they’ll give back your uncle.?

Lose and you’ll forfeit the Coil Runner and all his other creations.

在荒地死亡競速開始的前一天晚上，你的叔叔，偉大的發(fā)明家?斯雷特?·?卡諾利被殘忍的無幫派人士綁架了。

唯一救回他的方法 就是駕駛他的螺旋跑車親自和無幫派賽車。

贏了，他們就會放了你叔叔。

輸了，你就會失去螺旋跑車 和他所有的發(fā)明。

As the grueling race gets underway, you find yourself falling further and further behind.?

Your only chance is to take a shortcut your uncle told you about–– the Flux Ravine gambit.

Fortunately, the Coil Runner comes equipped with emergency turbo thrusters.

Unfortunately, your uncle was a notorious tinkerer, and the system still had some kinks to work out.?

Just minor things like the ignition exploding, the reactor leaking, or the oxygen levels depleting— any of which would end your racing career immediately.

艱難的競速賽正在進(jìn)行，你發(fā)現(xiàn)自己正落后得越來越遠(yuǎn)。

你唯一的機(jī)會是走 叔叔曾告訴你的那條近道——熔巖谷。

幸運(yùn)的是，螺旋跑車 裝備了緊急渦輪增壓推進(jìn)器。

不幸的是，你叔叔的 修理水平是遠(yuǎn)近聞名的差，車的系統(tǒng)仍有 一些小問題需要解決。

僅僅一些小問題， 如火星塞爆炸，反應(yīng)器泄漏，或者氧氣用盡——當(dāng)中的任何一個都可以 立即結(jié)束你的賽車生涯。

Before his kidnapping, Uncle Slate determined that each of these critical failures was the ultimate result of a chain reaction originating in the thrusters.?

He was also certain that while one factor could trigger two different effects, and two factors could each independently lead to the same effect, no effect is caused by two factors in conjunction.?

However, Uncle Slate never got around to pinpointing which thruster was responsible for which error.

在你叔叔被綁架之前，他判斷出這些嚴(yán)重故障中的任何一個都是推進(jìn)器中一個鏈?zhǔn)椒磻?yīng)的最終結(jié)果。

他十分肯定 一個因素會引發(fā)兩個不同的結(jié)果，并且兩個因素可以 各自獨(dú)立地引起同一個結(jié)果，沒有一個結(jié)果 是由兩個因素共同引起的。

但是，斯雷特叔叔還沒來得及找出哪個推進(jìn)器會引起哪個問題 就被綁架了。

All you have are the notes from his test runs: 1. When thrusters B and C are on, the Fuel gauge glows.?

2. When thrusters A, B, and D are on, the Fuel gauge glows and the Helium tank rattles.?

3. When thrusters C, D, and E are on, the Fuel gauge glows and the Gravitometer spins.?

4. When thrusters A, D, and E are on, the Gravitometer spins and the Helium tank rattles.

5. Shortly after the Helium tank rattles and the Gravitometer spins, the Ignition explodes and the Oxygen levels deplete.?

6. Shortly after the Fuel gauge glows and the Gravitometer spins, the Reactor leaks.

You need to use as many thrusters as possible to give yourself the best chance at clearing the gap, without triggering any of the three catastrophic failures.?

Which thrusters should you activate??

Answer in 3?

Answer in 2?

Answer in 1

你只有他測試跑車時記下的筆記：1.?當(dāng)開啟推進(jìn)器?B?和?C?時， 燃油量表會閃爍發(fā)光。

2.?當(dāng)開啟推進(jìn)器?A、B?和?D?時，燃油量表閃爍發(fā)光 并且氦氣瓶發(fā)出咔嗒聲。

3.?當(dāng)開啟推進(jìn)器?C、D?和?E?時，燃油量表閃爍發(fā)光 并且比重計旋轉(zhuǎn)。

4.?當(dāng)開啟推進(jìn)器?A、D?和?E?時，比重計旋轉(zhuǎn) 并且氦氣瓶發(fā)出咔嗒聲。

5.?在氦氣瓶發(fā)出咔嗒聲 并且比重計旋轉(zhuǎn)不久之后，火星塞爆炸并且氧氣耗盡。

6.?在燃油量表閃爍發(fā)光 并且比重計旋轉(zhuǎn)不久之后，反應(yīng)器泄漏。

你需要用盡可能多的推進(jìn)器使自己盡量縮小差距，且不會引起三個 毀滅性故障中的任何一個。

你應(yīng)該啟動哪個推進(jìn)器？

答案揭曉倒計時：3，2?，1?。

The most important thing to remember here is that even if we know that one thing causes another, the converse is not necessarily true.?

For example, this panic switch shuts off the coil runner’s engine.

But the engine being off doesn’t necessarily mean the panic switch was engaged— the coil runner could be out of fuel, or damaged— or turned off normally.?

We can, however, conclude that if the engine is running, the panic switch hasn’t been engaged.?

With that in mind, one way we can start is to work backwards from the three defects that could knock you out of the race.

這里你需要記住的最重要的信息是，即使一件事會引發(fā)另外一件事，反過來卻不一定成立。

比如，應(yīng)急開關(guān) 可以熄滅螺旋跑車的引擎。

但是引擎熄滅了并不意味著用了應(yīng)急開關(guān)——螺旋跑車可能沒油了 或者壞了——或者被正常關(guān)掉了。

但是我們可以推斷出 如果引擎還在運(yùn)行，應(yīng)急開關(guān)就沒有打開。

知道了這個，我們可以從會導(dǎo)致挑戰(zhàn)失敗的 三個缺陷中反向推導(dǎo)。

So let’s look at Slate’s last two notes, since they give direct information about those.?

The Gravitometer spins in both cases, but the results are different.?

That means the spinning Gravitometer can’t be the cause of any particular malfunction.?

If it were, the same thing would happen each time.

So we can conclude that a glowing Fuel gauge makes the reactor leak, while a rattling Helium tank makes the Ignition explode and depletes the Oxygen levels.

現(xiàn)在我們一起看看 斯雷特的最后兩條筆記，因為它們給出了 有關(guān)上述筆記的直接信息。

在兩個情況下比重計都會旋轉(zhuǎn)， 但它們的結(jié)果不同。

這意味著比重計旋轉(zhuǎn)不會是任何具體故障的原因。

如果它是， 那么每次都會發(fā)生同樣的結(jié)果。

所以我們可以推斷 閃爍發(fā)光的燃油量表使反應(yīng)器泄漏，咔嗒作響的氦氣瓶使點(diǎn)火塞爆炸，并且使氧氣耗盡。

Once we know which two errors we need to avoid, we can make a table and use the logic of cause and effect to see which thrusters trigger them.?

Since the Helium tank is fine during the first test run when thrusters B and C are active, we can assume neither makes it rattle.?

And from the third run we know that D and E don’t either.?

That leaves thruster A, which was indeed used in the second and fourth test runs where the Helium tank rattled.?

Now what causes the glowing Fuel gauge?

From the fourth test run we know it can’t be thrusters A, D, or E.

一旦我們知道了 哪兩個故障需要避免，我們就可列一張表，用因果邏輯來判斷哪一個啟動器引起它們。

因為氦氣瓶在第一次測驗啟動推進(jìn)器?B?和?C?時正常，我們可以推斷這兩個推進(jìn)器 都不會使它發(fā)出咔嗒聲。

從第三次測驗我們知道 推進(jìn)器?D?和?E?也不會。

那就只剩下推進(jìn)器?A?了，當(dāng)?shù)诙偷谒拇螠y試啟動它時，氦氣瓶會咔嗒作響。

那什么會引起燃油量表閃爍發(fā)光呢？

從第四次測試我們知道 不會是推進(jìn)器?A、D?或?E?。

So is the culprit, B, C, or each of them separately??

The answer can be found in the second and third test runs: the fuel tank glowed in both, but B was activated in one, and C in the other.?

That means the B and C thrusters each independently make the Fuel tank glow.

It looks like the A, B, and C thrusters are off limits.

Fortunately, the other two are just enough to clear the jump.

那么?B?和?C?到底誰是罪魁禍?zhǔn)祝?還是說它們都是 ？

從第二次和第三次的測試中 可以得到答案：燃油量表在兩次測試中都閃爍發(fā)光， 但是?B?只在一次測試中被啟動，而?C?在另一次被啟動。

這就說明?B?和?C?推進(jìn)器 各自獨(dú)立地使燃油量表閃爍發(fā)光。

看來?A、B?和?C?推進(jìn)器不能用。

幸運(yùn)的是，另兩個推進(jìn)器 足夠完成這次跳躍。

You rocket into first place and the gang begrudgingly hands over your uncle.?

He thanks you profusely, and decides to celebrate your victory with a cup of tea from his latest contraption...

你一躍成為第一名，無幫派人士不情愿地交出了你叔叔。

他對你表示了由衷的感謝， 并且決定慶祝你的勝利，獎勵了你從他那最新的 奇特裝置里倒出的一杯茶······
