Final answer:
Each paragraph in a press release should use block formatting, be left-justified, single-spaced with a double space between paragraphs, and use a professional font.
Step-by-step explanation:
The question pertains to the correct formatting of paragraphs in different types of written documents, such as press releases, business letters, and academic papers. In the specific context of a press release, each paragraph should be formatted with block formatting, meaning that text should be left-justified and not indented. Paragraphs should be single-spaced, with a double space between paragraphs to clearly separate them.
A professional font such as size 12 Times New Roman or Arial is recommended for good readability. This formatting style contributes to a clean, readable document that is preferred in professional communication.
