a list should be introduced with a colon when the list is preceded by\n○ a strong opinion.\n○ a complete thought.\n○ a dependent clause.\n○ a descriptive phrase.
Answer
Brief Explanations:
A colon is used to introduce a list when what precedes it is a complete thought. It separates the general statement from the specific items in the list. For example, "She bought three things: apples, bananas, and oranges." Here, "She bought three things" is a complete thought.
Answer:
a complete thought.
