What change is needed in lines 5 and 6?

• A. Change north America to North America.
• B. Change was to were.
• C. Change one's to ones.
• D. Make no change.

Answer: (A)

The correct answer involves changing "north America" to "North America" because proper nouns must be capitalized in English. "North America" refers to a specific geographic area, which includes countries like the United States, Canada, and Mexico. Proper capitalization of this term is important for clarity and grammatical accuracy.

Capitalization rules dictate that the names of continents, countries, and regions are treated as proper nouns, and therefore, they should always begin with a capital letter. In this case, changing "north America" to "North America" follows this rule and aligns the text with standard conventions of written English, enhancing its professionalism and correctness.
