Use the internet to find the terms of the Antarctic Treaty of 1961.
Select one of the articles of the treaty that you think is the most important.
Identify the title you have selected and summarize it. Then, explain to the reader why this is the most important article of the treaty.

Answers

Okay. So the Antarctic Treaty is basically talking about how Antarctica can never truly belong to anyone. It is a piece of land that isn't owned by anyone -- it's a completely independent area. The treaty, in essence, states that the land can only be used for peaceful research purposes, and that it has to be treated right. (Countries aren't able to come in and dump nuclear waste in Antarctica.) 

This treaty was really cool when it first came about, because it was one of the first times that all of these countries came together and agreed to do something strictly in the name of peace and science.

If I had to choose one of the most important articles of the treaty I would choose article 3, which states that all scientific research that is made in Antarctica is meant to be shared freely and openly with other countries. Without this article, you can see Antarctica as another kind of battleground entirely. People may not be shooting at a each other, but they're still competing in the same land for knowledge that they don't intend to share. With this article, that doesn't happen. All research is conducted for the sake of learning, not for the sake of gaining an upper hand on another country. This article makes it to where no one ever has any reason to be underhanded or secretive about what happens in Antarctica.

C-bimetallism.
D-activism.

Correct answer choice is :


B) Populism. Explanation:

The word populism came into use in the late 19th century beside the promotion of democracy. In the United States, it was nearly connected with the People's Party, while in the Russian Empire it was connected to the agrarian socialist Narodnik movement. During the 20th century, several parties appeared in advanced democracies that were defined as a populist.

The correct answer is B. Any political movement that represents the interests of the “common people” is known as populism.

Populism appeals to the people to build its power, understanding the people as low social classes without economic or political privileges. It usually bases its structure on the constant denunciation of the evils that the privileged classes embody. Populist leaders, therefore, present themselves as redeemers of the humble.
