Question

which sentence demonstrates correct punctuation?
a. my car is in the shop due to faulty brakes; therefore, i will be taking the bus to school.
b. last week, our class elected a new president, however; today she resigned from office.
c. when the principal called my name; i walked up to the podium and delivered my speech.
d. i went to the theater with dvida, my cousin, paolo, my friend, and zitska, my sister.

Explanation:

• Option A: "Therefore" is a conjunctive adverb. When used to join two independent clauses, a semicolon precedes it and a comma follows it, which is correct here.
• Option B: "However" is a conjunctive adverb. The semicolon should be after "however" (i.e., "president; however, today...") instead of before "however".
• Option C: "When the principal called my name" is a dependent clause, and a comma (not a semicolon) should follow it to introduce the independent clause.
• Option D: The commas in the list of people with their relationships are incorrect. It should be "I went to the theater with Dvida (my cousin), Paolo (my friend), and Zitska (my sister)" or use semicolons to separate the items with their descriptions for better clarity.

Answer:

A. My car is in the shop due to faulty brakes; therefore, I will be taking the bus to school.
