question 1
choose the sentence with the most correct grammar usage.
○ we plan to return some day to brazil; therefore, we want to visit rio, sao paulo, and manaus.
○ we plan to return some day to brazil therefore, we want to visit rio, sao paulo, and manaus.
○ we plan to return some day to brazil; therefore, we want to visit rio sao paulo, and manaus.
○ we plan to return some day to brazil, therefore, we want to visit rio, sao paulo, and manaus.

Explanation:

To determine the correct sentence, we analyze punctuation and list formatting:

1. "Therefore" is a conjunctive adverb. When connecting two independent clauses, it should be preceded by a semicolon (or a period and a new sentence) and followed by a comma.
2. In a list of places (Rio, Sao Paulo, Manaus), each item should be separated by a comma, and city names should be properly punctuated (e.g., "Rio, Sao Paulo, and Manaus" – not "Rio Sao Paulo").

• The first option uses a semicolon before "therefore", commas in the list, and correct city separation.
• The second option lacks a semicolon before "therefore".
• The third option incorrectly combines "Rio" and "Sao Paulo" without a comma.
• The fourth option uses a comma instead of a semicolon before "therefore".

Answer:

A. We plan to return some day to Brazil; therefore, we want to visit Rio, Sao Paulo, and Manaus.
