Answer:

Antarctica

Explanation:

The Drake passage refers to the water route that connects the southern part of South America and Antarctica. This passage was created long back, about 41 million years back. Before the creation of this passage, the region of Antarctica experienced a warmer type of climate.

The circumpolar Antarctic ocean current traveled through this passage, running in a clockwise pattern around Antarctica and it separated the Sub Antarctic warm water from the colder Antarctic current. This circumpolar Antarctic current is also considered as the West wind drift and this current maintains the extensively large ice sheets that are present currently, experiencing a much lower temperature.

Thus, the Drake passage separated Antarctica from the southern part of  South America.

zhuklara [117]

The correct answer to this open question is the following.

Who makes decisions to manage or regulate conflict in our society?

Answer: The federal government, the state government, the United States Congress with its two chambers(the House of Representatives and the Senate), and the judicial branch with all of its courts.

How are those "decision-makers" selected and by whom

Answer: United States citizens have the right to select the President of the United States and their representatives at the federal and state levels.  That is why they vote.

The leader of the United States is the President, who also is the chief of the executive branch and its cabinet. He is the most important decision-maker. At the state level, it is the governor. However, the US Congress and the state's congress also play a key roll in creating legislation.
