Final answer:
Without specific cartoons from Keppler, it is impossible to evaluate if his views on immigrants changed; thus, the answer is that there is insufficient information to determine.
Step-by-step explanation:
Based on the information provided, it is not possible to directly answer whether Keppler's views about immigrants changed between his first and second cartoons without having specific references to the cartoons themselves. Therefore, the correct answer would be option (c) Insufficient information to determine. When assessing political cartoons, it is crucial to consider the context, imagery, and captions the cartoonist uses to convey their argument.
The Dillingham Commission report and the social atmosphere described hint at a broader historical context of nativism and discrimination against immigrants, particularly those from non-European backgrounds, during the turn of the century. The cartoons mentioned would need to reflect whether Keppler's views aligned with or challenged this sentiment. Analyzing the evolution of an artist's perspective would involve examining changes in the content, tone, and message of their work over time.
