The billing clerk was not able to find the invoice ___ the order.
a. and
b. or
我選A答案是B,
對了答案之後,我馬上舊恍然大悟,的確是B....
只是選的當下,因為趕時間,所以直覺式選A....囧
因為在學程式的時候,
not (A and B) 是常用的東西...囧
表示非A也非B,所以在選這題的時候很直覺地選了and了....囧
我覺得好蠢啊XDDD

yard with a bat and said to himself, "Bottom of the ninth, Game 7 of the
World Series, the bases are loaded," and then envisioned hitting a home run
to win the game. My job is to shatter that dream."
