Environmental organizations want to preserve the land surrounding the Wilgrinn Wilderness Area from residential development. They plan to do this by purchasing that land from the farmers who own it. That plan is ill-conceived: if the farmers did sell their land, they would sell it to the highest bidder, and developers would outbid any other bidders. On the other hand, these farmers will never actually sell any of the land, provided that farming it remains viable. But farming will not remain viable if the farms are left unmodernized, and most of the farmers lack the financial resources modernization requires. And that is exactly why a more sensible preservation strategy would be to assist the farmers to modernize their farms to the extent needed to maintain viability.
In the argument as a whole, the two boldface proportions play which of the following roles?
我觉得从阅读的思路来讲,on the other hand一出,一定是一个对比,作者态度一定是一个复杂态度,而不是单一的支持或者反对;所以如果前面是否定了(ill-conceived),后面就一定是肯定了(sensible preservation strategy would be assist farmer)。从而只有答案是说在评估,而其他都是说支持或反对。 我觉得还是要读通原文。
