question 6 (5 points)
which punctuation mark would best fill in the blanks in the following sentence?
in the past year, i visited denver, colorado ____ portland, oregon ____ and seattle, washington.

a) slash
b) period
c) comma
d) semicolon

Explanation:

Analyze the structure of the list

The sentence contains a list of items that already include internal punctuation (commas separating cities and states):

• "Denver, Colorado"
• "Portland, Oregon"
• "Seattle, Washington"

Apply punctuation rules for complex lists

When list items themselves contain internal commas, semicolons must be used to separate the main items in the list to prevent confusion and clearly distinguish where each item begins and ends.

Determine the correct option

Replacing the blanks with semicolons yields: "In the past year, I visited Denver, Colorado; Portland, Oregon; and Seattle, Washington." This matches option D.

Answer:

• (A) Slash
• (B) Period
• (C) Comma
• (D) Semicolon (Correct answer)
