Question

1. the gap in the bridge. what topic does this political cartoon deal with and explain its meaning.

Explanation:

The political cartoon deals with the topic of the United States' isolationist stance after World War I. The bridge represents international cooperation. The gap in the bridge symbolizes the U.S. not joining the League of Nations (as the U.S. is the "keystone" that's missing). The President of the U.S. is on one side, while European countries (Belgium, France, England, Italy) are part of the bridge structure. This implies that without the U.S. (the keystone), the "bridge" (international cooperation through the League of Nations) is incomplete and unstable.

Answer:

The topic is the U.S.'s isolationism (specifically not joining the League of Nations) post - WWI. The meaning is that the U.S., as a crucial potential member (the "keystone"), is absent from international cooperation (the League of Nations, represented by the bridge with European countries), leaving the structure (international cooperation) incomplete and weak.
