C. People's point of view can change to suit changes in historical context.
Allow me to add some explanation about historical context and how that works.
When the Panama Canal was built in the early 1900s, the historical and political context was one of imperialism. President Theodore Roosevelt of the United States used military pressure and warships to force Columbia to recognize Panama's independence, and then arranged with Panama to cede a strip of land to the United States (for $10 million) so that the US could build the canal and control the canal zone for commercial purposes.
By the late 20th century, the historical and political context was much different, and imperialistic control of overseas territories was no longer in vogue. In 1977, US President Jimmy Carter signed a treaty with Panama which agreed to give over control of the canal to Panama by the end of the century, with transfer of control taking place on December 31, 1999.
Part of the reason for willingness to make that transfer was that the Panama Canal had become expensive for the United States to maintain and operate -- so that part of the historical context plays in also. Since Panama took over the canal, they have actually done very well financially with it. You could check out a good book on the subject,<em> The Big Ditch</em>, by Noel Maurer and Carlos Yu, published by Princeton University Press in 2010.
Option B is the right answer.
Darius is known as the King of the Persian empire. He became furious with the city-states of Greece because Athens (Greek city-state) tied up with other states to revolt against Persian rule. His anger led him to launch an armed force to defeat the Athenians. He thought his action of sending the army on the land of Athens would destroy the rebellious part of the empire. But the situation changed and the army of Darius was soon defeated in the hand of the Greek city-state in 490 B.C.
C. the liberation of Paris.
The people of Paris are gathered around celebrating.

Well, here is a hint. Anything ending in (.com) is not usually trustworthy, because they are usually trying to sell something, or are just not accurate. (.gov) is trust worthy I guess, but they are telling you what you want to hear. (WIKI IS NOT TRUSTWORTHY AT ALL) (.edu) would be the best, or (.org)
