我不太懂。。。这道题的论点难道不是——胜诉制度不会增加医疗失误的诉讼数量吗？那我这个逻辑和胜诉制度外的任何事情有关系吗。。。没有这个胜诉option人们诉讼量增多增少不影响胜诉制度单边对医疗失误的诉讼数量的影响啊？为什么b是对的......

对句意逻辑理解有误：因为，创造无意识的反应的应该是“情绪反应”而不是“个体”。所以后面的定从修饰的是emotional reactions

E确实认为不会同比例增长，但是没有提供reason

理解【核心结构】的概念：本选项的原因状语从句中出现了there be结构，这个句子的核心词是“有”。本题的主句中的主语是代词they，其指代对象是原因状语从句中的provisions of the new maritime code/ the new maritime code。若本选项成立，则两句的意思为：
因为这里有一个海商法，所以这个海商法引起了争端。

1.定从是就近修饰的，所以C中thought to be修饰kind显然不合适。fat of a kind需改为a kind of fat。a kind of是一个固定搭配，表示某一种，不能拆分。
2.C的that of略有赘余的嫌疑，虽然可以比较两种动物的脂肪，但比较两种动物已经足够清楚，所以这个that of可以不必要添加。

B中although从句和主句并无明显转折

screen，有“掩护，筛选”的意思
funds screen companies according to a variety of criteria，基金根据不同的标准来筛选公司
