A scientific team compared gold samples from several ancient artifacts with gold samples from an ancient mine in western Asia. ███ ██████ ██ ███ █████ ████████ ██ █████ ███████ ████ ███ ████ ████████ ███ ████ ████ ██████ ███ █████████████ ██████ ████ ███ █████ █████ █████ ██ ██ █████████ ██████ ████ ███ ████ ██ ███ █████████ ███ ███ ████ ███ ███████ █████
The author hypothesizes that the gold in the ancient artifacts was likely dug from a certain ancient mine. This is based on the fact that ratios of trace elements in the gold in the artifacts is very similar to the ratios of those elements in gold from the mine, and no other known mine has those same ratios.
The author assumes that the gold in the artifacts is likely to have come from a source that shares the same ratios of trace elements. The author also assumes that there are no other potential sources for the gold besides a mine.
