文章大意：本文是说明文。文章说明了杂货店排队方式以及研究人员提出的蛇形队伍的新方式，并分析了各自的利弊。
1 . You run into the grocery store to pick up one bottle of water. You get what you need, head to the front, and choose the line that looks fastest.
You chose wrong. People who you swear got in other lines long after you are already checked out and off to the parking lot.
It turns out, it’s just math working against you; chances are, the other line really is faster.
Grocery stores try to have enough employees at checkout to get all their customers through with minimum delay.
…
| A．Why does this always seem to happen to you? |
| B．So why don’t most places encourage serpentine lines? |
| C．Some of the may have stood in a queue for almost an hour. |
| D．The chances of your line being the fastest are only one in three. |
| E．How high is the probability that you are in the fastest waiting line? |
| F．With three registers, this method is much faster than the traditional approach. |
| G．But sometimes, as on a Sunday afternoon, the system gets particularly busy. |
