Final answer:
The correct use of a semicolon in the provided sentences is in sentence C, which joins two closely related independent clauses. Options A and B call for a colon to introduce a list, and option D does not require a semicolon as the second part isn't an independent clause.
Step-by-step explanation:
The appropriate placement for a semicolon in the given options is in sentence C. Here's why:
- A: When I travel, I take three important things: my journal, my money, and my passport. (The semicolon is not needed here; instead, a colon should be used to introduce a list.)
- B: Where would we all be if it wasn't for the three R's: reading, 'riting, and 'rithmetic? (Similar to A, a colon is appropriate before a list.)
- C: Oil prices keep on going up; something must be done. (This is correct use of a semicolon to connect two closely related independent clauses without a conjunction.)
- D: She looked deep into my eyes and said, "I love onions." (No semicolon is needed because the second part of the sentence is not an independent clause.)
To explain further, the use of a semicolon is appropriate when you're connecting two independent clauses that are closely related or when the second clause restates or otherwise complements the first. It's also important not to use a semicolon to separate words or phrases from the independent clause. Remember that a semicolon goes outside quotation marks when it's used.
