The definition of an intermediate conclusion is that it supports another sentence, at the same time it's being supported by another sentence.

But when I came across "PT70 - 1LR - Q17", I realized the difference between "cause and effect" and "premise and conclusion" can be quite subtle

Here's my question.

(1) A causes B,

(2) B causes C,

(3) C causes D.

Therefore, A causes D

Here, "B causes C" seems to be an intermediate cause between "A causes D".

Does it make (2) an intermediate conclusion? because it's supported by another sentence?

Just want some clarification because I think the different between Causation and Argument seem to be overlapping.

Like if say:

Because A, therefore B--- (That would be an Argument)

But if we say

B happens because of A--- (That seem to be both a Causation, and an Argument?)

Any thoughts?
