Final answer:
A comparison or contrast pattern in a paragraph is used to show similarities or differences between subjects, and it is true that they serve this purpose.
Step-by-step explanation:
True. A comparison or contrast pattern in a paragraph indeed shows likeness or differences between two or more subjects. These patterns are prevalent in various forms of writing and critical in analyzing, evaluating, and presenting information about different subjects. For example, when discussing political figures like Huey Long and Donald Trump, a compare and contrast paragraph can reveal insights into their rhetorical styles by examining how they are alike and how they differ.
This technique is not just limited to obvious similarities and differences but can also be applied in more nuanced contexts, where the writer highlights less apparent aspects of comparison or contrast.
