Final answer:
To support Vonnegut's main point in his letter, arguments can be assessed through the emotional appeal for solidarity, intertextual support from critics' works, and evidence provided for claims, including historical or expert references.
Step-by-step explanation:
To evaluate the arguments in support of Kurt Vonnegut's main point in his letter, consider the following strategies: Firstly, identify how the appeal to emotions is used, such as Peterson's call for solidarity to prevent the loss of the foreign language curriculum, which is presented as essential to maintain diversity and cultural understanding. Secondly, explore the role of intertextuality, where other critics' works serve to support an author's interpretation or provide counterarguments, enriching the author's stance. Lastly, consider the evidence presented to back up the claims, such as the author's use of specific examples, historical contexts, or expert opinions to underscore their point.
For example, a persuasive argument might be bolstered by citing texts across time, as Garrison does, to display continuity and relevance of the argument in question. Similarly, a cartoon analysis would involve identifying the main argument, the evidence supplied by the cartoonist, and evaluating the convincing nature of the argument. In historical arguments, such as those promoting or opposing a concept like slavery, determining the basic premise and identifying a modern parallel would be crucial.
