Final answer:
In an outline, Roman numerals typically represent main ideas, while capital letters denote specifics or details related to those main ideas. The number of detail sentences and paragraphs would primarily depend on each main topic's complexity.
Step-by-step explanation:
In the context of an outline, different elements correspond to various parts of the paragraph structure. Roman numerals usually represent main ideas or subtopics. Capital letters often relate to specific points or details under those main ideas. Detail sentences essentially elaborate on these points, thus may correlate with these capital letters. Introductory sentences would naturally tie to the broader topics or ideas, often signified by the Roman numerals. As for the number of detail sentences and number in paragraphs, these would depend on the depth and extent of your argument for each main idea or subtopic.
