Do not classify an inference from a surface impression. Write down its premises and conclusion first.
Step 1: Identify the subject and predicate of the conclusion.
Step 2: Locate the term common to both premises.
Step 3: Test whether the conclusion follows validly.
Step 4: Ask about the middle term in reality: is it a cause, effect, or another indicator?
The final question distinguishes limmī from innī, but the earlier checks are indispensable for a reliable classification.
