Quizplus · Accepted Answer

The best choice is D because the Indus River Valley civilization disappeared before 1500 B.C.E. and its writing is still undeciphered, which makes it difficult to learn more about their culture. Option A is not applicable to the Indus River Valley civilization as it is related to modern political situations. Option B is partly true, as the civilization did decline around 1800 B.C.E., but it did not entirely disappear at that time. Option C is also correct, but it cannot be the best answer as other options provide more specific information.
