Q 23. A poor farmer was fond of telling his children: “In this world, you are either rich or poor, and you are either honest or dishonest. All poor farmers are honest. Therefore, all rich farmers are dishonest.”

The farmer’s conclusion is properly drawn if the argument assumes that

(A) every honest farmer is poor
(C) everyone who is dishonest is a rich farmer
(D) everyone who is poor is honest

cranberry

A IS THE ANSWER

C IS TOO MUCH FOR A ASSUMPTION

D IS NOT ENOUGH TO SUPPORT THE CONCLUSION COS IT MEANS ANYONE WHO IS NOT HONEST IS RICH

when peopl say all A is B does not necessarily mean every B is A. So answer A is to say All honest farmer is poor. That "All honest farmer is poor" plus "All poor farmer is honest" means honest farmer is congruent with poor farmer.

because the farmer has already stipulated that people either rich or poor, either honest or dishonest. therefore, the farmer says "all rish farmers are dishonest"

one step further, we can also say "every (or all) dishonest farmer is rich", can we?!
