Final answer:
When using terms and abbreviations, write out the full names initially with the abbreviation or acronym in parentheses; subsequently use the abbreviation. In writing, classification-and-division paragraphs help structure the content by categorizing items or breaking down groups into smaller parts, such as identifying types of essential workers during a pandemic.
Step-by-step explanation:
When referring to terms and abbreviations, it is standard practice to write out full names the first time you use them in a document, followed by the abbreviation or acronym in parentheses. After this initial introduction, you can use the abbreviation or acronym for subsequent references. For instance, you would first write "U.S. Department of Agriculture (USDA)" or "Occupational Safety and Health Administration (OSHA)" and then refer to these organizations as USDA or OSHA henceforth. This approach helps to clarify the meaning of abbreviations for the reader and ensures that the document remains accessible and understandable.
Additionally, when structuring a report or essay, you may encounter classification-and-division paragraphs. Classification paragraphs categorize individual items into a larger group, whereas division paragraphs break down a larger group or a single item into its component parts. A classification example relevant to recent history could be identifying the different types of essential workers during a pandemic. An example sentence would be, 'During the pandemic, essential workers not under quarantine included employees in the fields of health care, childcare, transportation, water and wastewater, and agriculture and food production.'
