The moon's gravity is a sixth as strong as the earth's, so Chang'e-4's experiment was a test: would the earth plants know which way was up on the moon?

月球的引力是地球引力的六分之一，所以嫦娥四号的实验是一个测试：地球上的植物能知道月球上哪个是向上的方向吗？

Part of Chang'e 4's mission (使命) is to see how a moon base could be built for humans, including exploring (探索) whether humans could grow food and other plant products there.

嫦娥4号的部分使命就是探测怎样为人类建一个月球基地，包括探索人类是否能在上面种植食物和其他植物。

, okay. So 1 plus 1/4 of 0 is 1, so if Player II chooses 0, player I's best response is to choose 1.

是1,因为1+0/4=1,参与人II选0时I的最佳对策是1

So it'll be 1 plus 1/4 times 4, 1/4 times 4 is 1, so 1 plus 1 is 2, so Player II's best response in that case will be 2.

这回就是1+4/4,即1+1=2,所以此时参与人II的最佳对策是2
