2. All cattle ranchers dislike long winters.
All ski resort owners like long winters because long winters mean increased profits.
Some lawyers are cattle ranchers.
Which one of the following statements, if true, and added to those above, most supports the conclusion that no ski resort owners are lawyers?
(A) Some cattle ranchers are lawyers.
(B) Some people who dislike long winters are not cattle ranchers.
(C) All lawyers are cattle ranchers.
(D) All people who dislike long winters are cattle ranchers.
(E) All people with increasing profits own ski resorts.
答案是C,为什么？中间的关系似是而非的，怎么我就越看越不清了呢？
all cattle ranchers dislike long winter, but all ski resort owners like. So no cattle ranchers are ski resort owners.
Now stated some lawyers are cattle ranchers, and the conclusion is no ski owners are lawyers. If we assume all lawyers are cattle ranchers, we may obviously get the conclusion since ranchers are not owners.
