Final answer:
The statement about capitalizing nouns followed by numbers or letters is true. For instance, in 'IRS Form 1040' and 'Building A', the nouns are properly capitalized as they precede specific identifiers. The rule is also observed in titles and subtitles and when using proper nouns and abbreviations.
Step-by-step explanation:
The statement that nouns followed by numbers or letters should generally be capitalized, such as in 'IRS Form 1040', 'Building A', and 'No. 1.1' is true. This rule is part of proper noun capitalization, where specific identifiers that follow nouns are capitalized to denote unique entities. This is similar to capitalizing proper nouns like 'Monday', 'New Orleans', 'Mexico', and titles of works where important words are capitalized.
When introducing acronyms or abbreviations in a text, it is standard to write out the full names initially, followed by the abbreviations in parentheses, such as 'U.S. Department of Agriculture (USDA)'. Subsequent references in the text can use the acronym exclusively.
Moreover, in titles and subtitles, the first and last words, along with all major words, are capitalized, but articles, coordinating conjunctions, and prepositions are usually not, unless they are the first or last words in the title or at the beginning of a subtitle. An example of proper capitalization in a title would be: 'The Influence of Law on Society'.
