刚刷完OG有几个阅读方面的问题想请教大家：

第一个问题是OG的阅读里面的53题和第7题：

53. According to the passage, which of the following statements about sulfur dioxide and nitrogen oxide outputs is true?

(A) Older production technologies cannot be adapted so as to reduce production of these outputs as waste products.

(B) Under the most recent environmental regulations, industrial plants are no longer permitted to produce these outputs.

(C) Although these outputs are environmentally hazardous, some plants still generate them as waste products despite the high compliance costs they impose.

(D) Many older plants have developed innovative technological processes that reduce the amounts of these outputs generated as waste products.

(E) Since the production processes that generate these outputs are less costly than alternative processes, these less expensive processes are sometimes adopted despite their acknowledged environmental hazards.

我知道答案是C，可是我不能理解的是为什么C是according to the passage得出来的，而不是infer出来的？
然后第7题：
7. The passage implies that which of the following is a possible consequence of a company’s adoption of innovations that increase its ecoefficiency?
(A) Company profits resulting from such innovations may be reinvested in that company with no guarantee that the company will continue to make further improvements in ecoefficiency.
(B) Company growth fostered by cost savings from such innovations may allow that company to manufacture a greater number of products that will be used and discarded, thus worsening environmental stress.
(C) A company that fails to realize significant cost savings from such innovations may have little incentive to continue to minimize the environmental impact of its production processes.
(D) A company that comes to depend on such innovations to increase its profits and growth may be vulnerable in the global market to competition from old-style eco-inefficient industries.
(E) A company that meets its ecoefficiencygoals is unlikely to invest its increased profits in the development of new and innovative ecoefficiency measures.
这个答案是B我能作对，但是，我就是觉得为什么这个就是imply，我咋觉得是according to 就能得出的呢？

我现在不是很清楚什么样的答案算是infer/suggest/imply出来的，什么样的答案算是according出来的？标准是什么呀，怎么区分呀？

第二个问题是，新东方的阅读老师的讲的文字定位法是否能用？新东方说，如果能够从题目给的信息准确定位在原文中的唯一一个段落，那么，如果有选项出现其他段落中的信息，那么那个必错，不用再去分析那个选项了？我想问，这个好悬啊，真的能用在GMAT里面吗？

第三个问题是：新东方的老师说统计学规律显示：主旨题里面有reconcile的选项必定错的，这个能信不？

第四个问题是：新东方老师说态度题里面如果有一个选项有incomplete，则那个选项必定对，能用上吗？


谢谢大家指教！O(∩_∩)O~
