Question

when are colons used? select three options.
a colon separates clauses in a series.
a colon signals that a list follows.
a colon appears in 12-hour time notations.
a colon is used after an introductory phrase.
a colon follows the greeting in a formal letter.

Explanation:

• A colon signals a list (e.g., "Items: apple, banana").
• In 12 - hour time (e.g., 2:30 PM), a colon separates hours and minutes.
• In formal letters, the greeting uses a colon (e.g., "Dear Sir:").
• Separating clauses in a series is not a colon's use (semicolons or commas are for that). Using a colon after an introductory phrase is incorrect (it's for independent clauses or lists).

Answer:

B. A colon signals that a list follows, C. A colon appears in 12 - hour time notations, E. A colon follows the greeting in a formal letter
