Answer: A. The eagle represents the willingness of the United States to use force to protect its territories.
Explanation: This question was supposed to be accompanied by a political cartoon and a sub line stating that it was a political cartoon made for the purpose of supporting imperialism. As those who will be requiring the answer to the question will already have access to both of these, no further explanation is required.
While referencing both of the previously mentioned materials, the question can easily be solved via process of elimination.
B. The eagle shows that the United States has expanded enough.
This is incorrect because a political cartoon created for the purpose of supporting imperialism wouldn't give off the message that the United States no longer needs to expand.
C. The eagle represents the threat the United States poses to other countries.
This is incorrect because the eagle is not looming nor gazing menacingly at other countries, rather its feet are planted firmly on the United States and its eyes are half-closed, the latter suggesting that the eagle is not focused, and therefore does not intend to commit to any type of action in the near future.
D. The eagle shows that United States values freedom and liberty.
This is incorrect because although eagles are typically associated with freedom and liberty, the eagle shown in the political cartoon shows no intention of flying anywhere due to the fact that its wings are pointed toward the earth. As birds in flight are usually considered to be the utmost symbol of freedom (due to the sheer amount of maneuvers they can employ while in the air), an eagle that isn't flying would not be meant to represent freedom and liberty.
After eliminating B. C. and D., there is no other option for the correct answer to be other than A. The eagle represents the willingness of the United States to use force to protect its territories.
