Answer:
1. Our answers are correct, but their answers are incorrect.
2. Your clothes are new and your shoes are new.
Explanation:
In number 1, we have two independent clauses with contrasting ideas. The first one affirms the subject's answers are correct. The second one affirms the other subject's answers are incorrect. For that reason, it is best to use the conjunction "but", which conveys a contrasting idea:
Our answers are correct, but their answers are incorrect.
In number two, the two clauses are expressing similar ideas instead of contrasting ones. The second idea basically adds to the first one: someone has new things - clothes and shoes. The best conjunction in this case is "and", which conveys an idea of addition:
Your clothes are new and your shoes are new.
A foil is a character that is the opposite of the protagonist, but not necessarily in a bad way. It only means they have opposite qualities--it does not mean that they are the antagonist of the main character. Antithetical character are normally their "enemies"--they are the antithesis. Think antithesis of the main character.
The answer is option four.
