Cause and effect vs. Premise and intermediate conclusion

lx621146

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?

I think it's just an intermediate premise, because it doesn't say something like 'B causes C because B causes A which causes C.' In my opinion, that's just an fact, not a conclusion.
