One proposal for preserving rain forests is to promote the adoption of new agricultural technologies, such as improved plant varieties and use of chemical herbicides, which would increase productivity and slow deforestation by reducing demand for new cropland. Studies have shown that farmers in developing countries who have achieved certain levels of education, wealth, and security of land tenure are more likely to adopt such technologies. But these studies have focused on villages with limited land that are tied to a market economy rather than on the relatively isolated, self-sufficient communities with ample land characteristic of rain-forest regions. A recent study of the Tawahka people of the Honduran rain forest found that farmers with some formal education were more likely to adopt improved plant varieties but less likely to use chemical herbicides and that those who spoke Spanish (the language of the market economy) were more likely to adopt both technologies. Nonland wealth was also associated with more adoption of both technologies, but availability of uncultivated land reduced the incentive to employ the productivity-enhancing technologies. Researchers also measured land-tenure security: in Tawahka society, kinship ties are a more important indicator of this than are legal property rights, so researchers measured it by a household's duration of residence in its village. They found that longer residence correlated with more adoption of improved plant varieties but less adoption of chemical herbicides.
The primary purpose of the passage is to
evaluate the likelihood that a particular proposal, if implemented, would ultimately succeed in achieving its intended result
question the assumption that certain technological innovations are the most effective means of realizing a particular environmental objective
discuss the progress of efforts to encourage a particular traditional society to adopt certain modern agricultural methods
present the results of new research suggesting that previous findings concerning one set of conditions may not be generalizable to another set of conditions
weigh the relative importance of three factors in determining whether a particular strategy will be successful

正确答案是D。选择D的原因是，文章讨论了“一个特定的传统社会如何采用现代农业方法”的进展，并提出了新研究结果，表明以前关于一组条件的发现可能无法推广到另一组条件。
A.文章并非说 用了这个技术后能不能达到效果，而是有没有人用这个技术以及哪些人更可能用这个技术
B. most efficient绝对词
C. 鼓励使用，文章没有鼓励使用，而是客观描述那些人会使用
D. 定位第三句话，提出了以前的研究的局限性，并举了T地的例子来说明以前finding没有提到的情况
E. 没有在衡量成功率，还是客观描述哪些人更可能使用这个新技术
错选了Ａ，这个题看了答案给我一种CR的方案推理的感觉，Ａ写的是这个方案能不能成功达到目的，但是文章讲的是方案能不能成功实施，也就是D
开头先说为保护热带雨林，农业应该增加种植多样性并且使用化学除草剂，但是发展中国家贸易地区与相对独立的地区人们的接受结果是不一样的。注意：开头一二句不一定是文章的主旨，可能是为了引出主旨而说的一个背景。实际，文章大幅度论证论据要证明的才是文章主旨，即“But these studies have focused on villages with limited land that are tied to a market economy rather than on the relatively isolated, self-sufficient communities with ample land characteristic of rain-forest regions ”. 因为从文章结构上看，后面都是对这个观点的论证论据， A recent study of the Tawahka people....Nonland wealth was also ...Researchers also...
从答案倒退可以理解，但是感觉选项很隐晦，正选还是未必选的出。

particular proposal, if implemented, would ultimately succeed in achieving its intended result
➡️ 如果农民们用了新的农业技术，雨林会不会真的得到保护？（土地的生产力会不会增加？农民对土地的需求会不会减少？）
developing countries 能做到，但雨林等地区的农户不太行
文章从第三句开始是重点，特别是but，前面说的一种实验条件跟后面实验的前提条件是不一样的，所以就对应了D选项
错选了，重点应该是But these studies have focused on villages with limited land that are tied to a market economy rather than on the relatively isolated, self-sufficient communities with ample land characteristic of rain-forest regions. 对应d的one set和another set
Studies have shown that farmers in developing countries who have achieved certain levels of education, wealth, and security of land tenure are more likely to adopt such technologies.
But these studies have focused on villages with limited land that are tied to a market economy rather than on the relatively isolated, self-sufficient communities with ample land characteristic of rain-forest regions.

错选了E选项
读完没有很清晰的总结出文章的大致结构，只记得后面忘了前面。文章前面先是说了在developing countries 中，具有xxx条件的农民更倾向于采取新技术。然后转折说这个研究具有局限性，那些自给自足的相对独立的社会形态不一定适用。进一步解释了在这种背景下不同条件影响技术的应用情况。
而不是衡量success
e 如果strategy指的是adoption of new agricultural technologies，那么文章讨论重点并非是非会成功preserve rain forests，而是strategy能否被采纳，错误类似a
d 文章第二句Studies have shown that介绍了主题，但是previous findings concerning one set of conditions里的 one set of conditions又在哪里？？
重点：分析文章结构
本文没有说成功性，说的是影响proposal被接受的程度的因素。
But these studies have focused on villages with limited land that are tied to a market economy rather than on the relatively isolated, self-sufficient communities with ample land characteristic of rain-forest regions
But these studies have focused on... A recent study of the Tawahka ...
旧proposal->有漏洞->新研究
But these studies have focused on villages with limited land that are tied to a market economy rather than on the relatively isolated, self-sufficient communities with ample land characteristic of rain-forest regions. 答案的one set of conditions , another set of conditions应该就是文中的Limited 和ample吧，说明两者的不同
A选项说评估了这个proposal执行的成功性，本文没有说成功性，说的是影响proposal被接受的程度的因素；
