Which sentence uses the superlative degree? a.) jerry is the more organized of the two. b.) greg is a fantastic math teacher. c.) marley is the most interesting person i have known.?

Remember that superlatives as define the highest possible quantity or characteristic. They can be found easily by the common use of the -est ending, or the use of the word most. For example: "I am the best. I am the smartest. I am the most capable."

In this case, the answer would be C, "Marley is the most interesting person I have known." The use of the word most shows this.

Hope this helps!
