Final answer:
The sentence that correctly uses colons and semicolons is 'The passengers on the bus include these three people: Mr. Smith; Mrs. Thompson; and Theresa Martinez, the team's best player.' A colon introduces the list after an independent clause, and semicolons separate complex list items.
Step-by-step explanation:
The correct sentence that uses colons and semicolons properly is: The passengers on the bus include these three people: Mr. Smith; Mrs. Thompson; and Theresa Martinez, the team's best player. In this sentence, the colon is used after an independent clause to introduce a list, whereas the semicolons are used to separate elements in a sequence when those elements already have commas within them or are individual list items that are complex.
Here's why the other sentences are incorrect:
- The passengers on the bus include these three people, Mr. Smith, Mrs. Thompson, and Theresa Martinez merges list items with commas only, which is usually fine unless the list items themselves contain commas.
- The passengers on the bus include these three people; Mr. Smith, Mrs. Thompson, and Theresa Martinez incorrectly uses a semicolon to introduce a list, which is the role of a colon.
It is clear that in order to ensure clarity in complex lists, and to correctly introduce a list after an independent clause, using a colon and semicolons appropriately is essential.
