Dear Trump,
In the future, I believe that the state of Oklahoma should not use fossil fuels as the primary source of energy. Instead, I think the state should create a miniverse, where inside that miniverse, the inhabitants can use physical labor to create a source of power where 20% is used for the inhabitants of the miniverse, and the remaining 80% should be sent through the miniverse to power our homes and car batteries. This may sound like slavery with extra steps to you, but if you disagree, you're probably getting laid in college or something. This offer is completely valid, and it should be taken into consideration in exchange of fossil fuels, which continues to pollute our planet. Take note, a miniverse causes no pollution.
Yours truly,
Person who asked this question
The U.S. placed Cuba undr a quarantine.
A new treaty was negotiated due to riots in Panama.
The most correct option from those listed here is the second option: The assignment was originally due on Tuesday; however, the instructor changed the due date to Thursday.
The first and third options awkwardly have the word "however" capitalized in the middle of the sentence, and the last option uses the semicolon completely wrong (you're supposed to use it to connect two independent clauses).
Hope this helps. Do let me know if you have further questions.
