Well recall from week zero when we took a very real world phonebook and then just last week we had our volunteer come up with the array of pieces of paper on the board and when I challenged myself and when I challenged our volunteer to find me the number 50 both he and I were able 50 to leverage one assumption.

大家回忆一下,当我们拿着一个现实世界的电话簿,就在上周我们的志愿者,在黑板上提出了纸片的阵列,我挑战自己，也挑战志愿者,要找出同一个,数字。
