求教个多项条件推理的思路

题目是这样的,很短:

Any person who drops out of high school will be unemployed unless he or she finds a low-paying job or has relatives with good business connections.

这个的思路是什么?

(逃学+没工作)取非推出 low paying+ has relatives???那这样的逆否命题又怎么写呢?

而且后面有道题是,假定Tom is employed and does not have a low-paying job

结论题为什么答案是Tom is a high school dropout and does not have any relatives呢?

我觉得要么是does not have any relatives and he is not a high school dropout ,要翻过来
