Which sentence correctly illustrates the use of a semicolon?

• A. I have a big test tomorrow; I can't go out tonight.
• B. I have a big test tomorrow; and I can't go out tonight.
• C. I have a big test tomorrow: I can't go out tonight.
• D. I have a big test, tomorrow; I can't go out tonight.

Answer: (A)

The sentence "I have a big test tomorrow; I can't go out tonight." effectively demonstrates the correct use of a semicolon. A semicolon serves to connect two independent clauses that are closely related in thought. In this case, both clauses—"I have a big test tomorrow" and "I can't go out tonight"—can stand alone as complete sentences, yet they are linked by the context of the speaker's obligation to study for the test, making the semicolon appropriate. The other sentences misuse punctuation in various ways. For instance, the inclusion of the word "and" before the second clause in one of the choices suggests that a coordinating conjunction is being used, which calls for a comma rather than a semicolon. Another option improperly uses a colon, which is meant to introduce a list or explanation rather than connect two independent clauses directly. Lastly, the incorrect placement of a comma before "tomorrow" does not properly separate elements within the sentence as intended. Therefore, the initial sentence stands out as the correct illustration of semicolon usage.
