Question: 525

• A. NO CHANGE
• B. For centuries, North Americas’ continental
• C. For centuries, North America’s continental
• D. For centuries North Americas’ continental

Correct Answer: C

Explanation:

(C) The idea that should be expressed as a possessive is the continental shelf of North America. Choice (A), by omitting an apostrophe, fails to illustrate possession. Choices (B) and (D) read as if the continent were North Americas, as opposed to the correct North America.
