Attachments to conditional parts

PirateParty

Hi, I've been on a hiatus for a few months and came across a problem while reviewing NA questions on the syllabus and remember having this issue in the past as well.

https://7sage.com/lesson/computer-emotions-na-question/?ss_completed_lesson=1791

Here JY attaches a noun (computer) to another noun (emotions) instead of writing it as, and as I wrote it, C->/E he writes it as /Ec

Then he wrote the conclusion as follows /Ic, I wrote it as C-> /I

So how can I know when to attach one thing to another in conditional reasoning? Is there a general rule to this? Because it lead me to the following issue with this problem.

I created a chain where both E and I connect to /C however I'm not able to see which comes first inorder to validate the conclusion, the /E or the /I
(diagramed below)

P:C - > /E

SA: I->E or E->I

C - >/I

JY, and the correct answer choice, both did it as I->E - I understand how they got to that when he attaches the c to /E.

Im not sure if my conditionality is off or what, but I would have assumed that it wouldn't matter if I attached the two nouns together or just created it the relationship in the chain as above. If anyone needs more clarification on anything please let me know.
