The following was excerpted from the speech of a spokesperson for Synthetic Farm Products, Inc.:

“Many farmers who invested in the equipment needed to make the switch from synthetic to organic fertilizers and
pesticides feel that it would be too expensive to resume synthetic farming at this point. But studies of farmers who
switched to organic farming last year indicate that their current crop yields are lower. Hence their purchase of organic
farming equipment, a relatively minor investment compared to the losses that would result from continued lower crop
yields, cannot justify persisting on an unwise course. And the choice to farm organically is financially unwise, given that it
was motivated by environmental rather than economic concerns.”

关于第一段： 这道题的conclusion到底是什么啊？

是不是farmers should switch to synthetic farming rather than persist in an unwise course - organic farming. 然后说author reasons that研究表明去年转向organic farming的农户都遭受了低产，然后又agrue说在organic设备上的的投资相较持续的低产小的多，最后说转向organic farming 在财政上不明智，因为只是motivated by environemental rather than economic concerns

关于提纲： 1. 忽略他因或者无因果，低产可能不是organic farming造成的
          2. doubtful study: 这几个农户的案例不能代表整体情况
          3. 也没有evidence证明第一年的低产会持续下去，可能第二年就有质和量的飞跃，抵消第一年低产带来的损失


各位NN非NN，好心的兄弟姐妹帮我看看吧，我脑子都搅糊涂了。。
