Happily, yournoona! There are a few indicators that can help, and the first is the presence or absence of the phrase "if true" or some variant (if accepted, if valid, if accurate, etc.) A Justify question must include such a phrase, because you are not looking for something that absolutely must be true, but rather something that IF it was true would prove the conclusion. That's why Justify questions are also known as "Sufficient Assumption" questions - they are sufficient to prove the conclusion.
An Assumption question stem will NEVER use such a phrase! There is no "if" about assumptions - they must be true in the author's mind if their argument is to make sense. That's why Assumptions are also known as "Necessary Assumptions" - they are required, but they don't have to be sufficient.
Another way to tell is through the presence or absence of words indicating that the conclusion is proven - "properly drawn," "follows logically," "must be true," etc. A Justify question will use those sort of phrases, indicating that the conclusion follows from the correct answer. An Assumption question avoids those phrases, because the conclusion doesn't have to follow from the correct answer. It's the other way around - the answer follows from the conclusion!
This stem has no "if true" phrase, and it has no "follows logically" language, so it cannot be a Justify question. it asks "which one of the following IS an assumption," and that tells you what you need to know! Find the assumption, not the justification.
