premise: Five artifacts—V, W, X, Y, and Z—recovered from a sunken ship are each known to have originated in Iceland, Norway, or Sweden. These artifacts, together with the surviving fragments of a cargo list, have enabled historians to determine the following: W and Y originated in the same country. X originated in Norway or Sweden. More of the artifacts originated in Iceland than in Norway. If V originated in Iceland, then Z originated in Sweden. Which one of the following could be an accurate matching of the artifacts to their origins?
hypothesis: Iceland: V, W Norway: X Sweden: Y, Z
