1. "I learned all the rules and regulations of basketball; however, I never really learned to handle the ball very well."
In this sentence, a semicolon is used to separate two independent clauses that are closely related in thought. The first clause is "I learned all the rules and regulations of basketball," and the second clause is "I never really learned to handle the ball very well." The conjunction "however" is used to show contrast between these two ideas.
2. "When you report for the test, make sure you have the following items with you: at least three sharpened No. 2 pencils, your entrance ticket, and a picture identification."
Here, a colon is used after the phrase "the following items with you" to introduce a list of items. The items in the list are separated by commas.
3. "Richard had three choices: have the car fixed, buy a new one, or do without."
In this sentence, a colon is used after "three choices" to introduce a list of options. The options in the list are separated by commas.
