I believe the answer is: A. Dante believed that a sinners punishment should be a serve as his sin
In Dante's inferno, hell is divided into several levels, and the punishment/torture that given to humans would be most severe as the sinners go down to the lower levels. The first level on Dante's circle of hell is given to the people who do not believe in Christianity while the lowest level is given to the traitors of christianity.
the answer is D. Some of the world’s highest waterfalls can be found in three countries: Venezuela, South Africa, and Peru.
a colon in a sentence means the auther can end the sentence with a period if he wanted and the sentence would still be correct.
in this case the sentence could be, "Some of the world’s highest waterfalls can be found in three countries."
this still looks and sounds correct and is a fully functioning sentence.
