Explanation
Choice C is the best answer. The historian claims that the countries where Schliemann's excavations took place experienced a surge in commercial and financial activity. If an overwhelming number of tourists boosted local business revenues in the region, then that would support the historian's claim.
Choice A: The methods Schliemann used for excavation are not discussed in the text.
Choice B: The historian's claim is about Schliemann's economic impact after his discovery, not what the discovery revealed.
Choice D: The historian's claim makes no reference to Schliemann's previous career or how his excavations were financed.
