"unless this condition of things does change, then"
The part of the excerpt that explains why Americans had reached the "end of the frontier" is: "For a moment, at the frontier, the bonds of custom are broken and unrestraint is triumphant."
To find the part of the excerpt that explains why Americans had reached the "end of the frontier," we need to look for a sentence or phrase that discusses the closing or disappearance of the frontier.
In the given excerpt, the relevant part is: "For a moment, at the frontier, the bonds of custom are broken and unrestraint is triumphant."
This sentence suggests that the "frontier" is no longer accessible or available, and that is why Americans had reached the "end of the frontier." The phrase "for a moment" implies that this situation is temporary and that the frontier has ceased to exist.
Therefore, the correct answer is: "For a moment, at the frontier, the bonds of custom are broken and unrestraint is triumphant."
