On her way home from work, Janet drives through several tollbooths. Is there a pair of these tollbooths that are less than 10 miles apart?
(1) The first tollbooth and the last tollbooth are 25 miles apart.
(2) Janet drives through 4 tollbooths on her way home from work.
Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
EACH statement ALONE is sufficient.
Statements (1) and (2) TOGETHER are NOT sufficient.
有4个收费站共25米,4各收费站会形成3段路,若每个等于10米,共需要30米;现在只有25米,所以一定存在 两个收费站之间小于10米的情况 充分。选c
这个题首先,题干没读懂。
tollbooth 收费站
问:是否存在 任意两个收费站之间的距离小于10米 的情况?
12单独不充分
12结合来看。

这个题读到的时候云里雾里,然后只是在脑子里过了一下,没有画图落实到纸面上分析,思考的不全面。
