Quick Question regarding only if

I have a quick question on the meaning of only if. I realize that for an example if a statement says: An living organism is a human only if the organism is not a dog. I know that can translate to If a living organism is a human, it is not a dog. However, in a MBT, MSS, or NA scenarios, would the use of ONLY IF potentially count the answer choice wrong even if the statement has identitical conditional structures? For an example: What if its the case that A living organism that is human is not a cat? A bird? a plane?

    Doesn't the sufficient condition come "after" the ONLY IF...?

    pretty sure only if implies a necessary condition

    Only if does imply a necessary condition. Meaning for your original statement, in order for a living organism to be a human, it must meet the condition that it is a dog. But just because it meets that condition doesn't mean it is a human. However, what you can imply is the contrapositive: if a living organism is a dog, you know for sure it is not a human.
