Exactly how many of the artifacts are there any one of which could have originated in Norway?

Still confused

I've watched the video explaining question number 17 multiple times and I am still not understanding how 3 artifacts can come from Norway. One of the rules is thatbmore artifacts have originated in Iceland than in Norway, and if 3 originate in Norway, then only 2 would come from Iceland which would break that rule.

Happy to help! I think you're misreading what the question is asking for. You're right—in any one sub game board, I must have more artifacts than N, so the most artifacts that N could have in a game board is 2. However, that's not what the question is asking. The question is asking exactly how many of the artifacts are there any of which could have originated in Norway? The key words in this phrase are "any one of which," and this question is basically asking us, "if we examine all of the possible game boards for this problem, which of the artifacts could potentially be in N?"

We know that WY can't go into N because in that game board, we would have to put the other 3 artifacts into I, and that would contradict the rule that if V is in I - ->Z is in S

Let's check the other artifacts.

If we put Z in N, WY in I, and V and X in S, we have


This satisfies all of our rules.

Now, what if we put X and V in N? (This game board is from answering the second question)


This game board also satisfies all of our rules. From these two game boards, we see that Z, X, and V are all artifacts that could theoretically go into N. Therefore, we know that there are 3 artifacts that could have originated in Norway, so our answer is C.

Does this make sense? Let us know if you have more questions!
