求区分因果推理和相关因果推理的区别！谢谢各位大神

刚开始接触herl的逻辑做题方法，可是这两个分不太清，求大神帮忙

个人愚见：相关因果：若a事件发生，b事件也平行发生，结论：a导致b发生(强调a.b之间的相关联系)
若用图形表示则是
————a

————b
然后a与b之间有个a指向b的箭头，（操作有些难。。）

因果是a直接作用于b（强调因果）
图形表示则为箭头a→b。

刚刚做了og的一道题，我觉得相关因果和因果好难判断啊

8. In virtually any industry, technological improvements increase labor productivity, which is the output of goods and services per person-hour worked. In Parland’s industries, labor productivity is significantly higher than it is in Vergia’s industries. Clearly, therefore, Parland’s industries must, on the whole, be further advanced technologically than Vergia’s are.

The argument is most vulnerable to which of the following criticisms?
(A) It offers a conclusion that is no more than a paraphrase of one of the pieces of information provided in its support.
(B) It presents as evidence in support of a claim information that is inconsistent with other evidence presented in support of the same claim.
(C) It takes one possible cause of a condition to be the actual cause of that condition without considering any other possible causes.
(D) It takes a condition to be the effect of something that happened only after the condition already existed.
(E) It makes a distinction that presupposes the truth of the conclusion that is to be established.
因果推理。科技进步促使劳动生产率提高；P>V ，因此P科技比V 先进（结论）。
抓住因，找因果概括或干扰因素。
A 结论并不是一个信息的改述，是推出了东西
B 并不与其他论据冲突
C 文中没说有别的cause
D 正确。即充分但不必要
E 无关
