Final answer:
The sentence that best evidences the cultural exchange influenced by Hokusai's artwork describes the Great Wave as a symbolic barrier and a representation of potential cultural interchange, reflecting the complexities of Japan's artistic contributions and exchanges with the West.
Step-by-step explanation:
The sentence that provides the most effective evidence to support the claim about the significance of Hokusai's artwork and the cultural exchange between Japan and the West is, "So this great wave seemed, on the one hand, to be a symbolic barrier for the protection of Japan, but at the same time it had also suggested the potential for the Japanese to travel abroad, for ideas to move, for things to move back and forth." This sentence encapsulates the dual nature of the influence of Japanese art, symbolized by Hokusai's The Great Wave off Kanagawa, on the world and vice versa. It signifies the wave as a barrier that protects Japan's culture, while also hinting at the beginning of cultural exchanges between Japan and other countries, including the influence of linear perspective from Western art traditions and the exportation of ukiyo-e prints, which inspired European artists.
