question 14\nwhich of these is the proper format for an outline?\n○ 1., a, i\n○ i., a., 1\n○ a., i, a.\n○ a. ,a., i
Answer
Brief Explanations:
A proper outline format uses a hierarchical structure with Roman numerals (I, II, III...), then capital letters (A, B, C...), then Arabic numerals (1, 2, 3...), etc. The option "I., A., 1" follows this hierarchy: Roman numeral first, then capital letter, then Arabic numeral, which is the correct outline formatting sequence. Other options mix the order incorrectly (e.g., starting with Arabic numeral before Roman, or misordering capital letters and numerals).
Answer:
B. I., A., 1 (assuming the second option is labeled B; if original options have no labels, based on the list: the second option "I., A., 1" is the correct one)
