Which examples of headings and lists are capitalized correctly?

The first choice is capitalized correctly because it follows the standard conventions for title capitalization in English. When referencing the title of a book, in this case, "Aspects of Advanced Programming," the key words are capitalized according to title case rules. This means that nouns, pronouns, verbs, adjectives, and adverbs are capitalized while minor words such as conjunctions and prepositions are not unless they begin the title.

In contrast, the other sentences do not represent titles; they are either statements or lead-ins to lists. Therefore, standard capitalization rules apply. For instance, the second choice lists agenda items but does not need title case capitalization since it is not the title of a document or work. The third choice presents a warning within a statement, again, unrelated to title case. The fourth choice introduces discussion topics but is structured as a standard sentence rather than a title.

Overall, understanding when to use title case versus standard sentence capitalization is crucial in professional communication, particularly when dealing with titles and lists.
