Economist: Paying extra for fair-trade coffee——coffee labeled with the Fairtrade logo——is intended to help poor farmers, because they receive a higher price for the fair-trade coffee they grow. But this practice may hurt more farmers in developing nations than it helps. By raiding average prices for coffee, it encourages more coffee to be produced than consumers want to buy. This lower prices for no-fair-trade coffee and thus lowers profits for non-fair-trade coffee farmers.
To evaluate the strength of the economist’s argument, it would be most helpful to know which of the following?
Whether there is a way of alleviating the impact of the increased average prices for coffee on non-fair-trade coffee farmer’s profits
What proportion of coffee farmers in developing nations produce fair-trade coffee
Whether many coffee farmers in developing nations also derive income from other kinds of farming
Whether consumers should pay extra for fair-trade coffee if doing so lowers profits for non-fair-trade coffee farmers
How fair-trade coffee farmers in developing nations could be helped without lowering profits for non-fair-trade coffee farmers
A的问题在哪里呢
题目的conclusion是 hurt more farmers in developing nations than it helps
B是直接在论证是否是more farmers 利益受损 而A却没有
这个解释不太合理，这里的比较对象是this practice hurt more than it helps,是伤害性比帮助大，不是伤害农民的数量的比较
a不管有没有方法减轻生产non-fair-coffee的农民的伤害，伤害就是伤害，不会因为减轻而不存在。
