C . but, it is even more basic for students to complete high school and attain at least a bachelor’s degree.
D . so it is even more basic for students to complete high school and attain at least a bachelor’s degree.
E . it is even more basic for students to complete high school and attain at least a bachelor’s degree.

Answer: E

Explanation:

This sentence is a run-on sentence and can be fixed with the deletion of one word: “therefore.” By beginning with a conjunction such as “Since” the sentence already has a descriptive clause in motion and just needs to be followed by a succinct (brief) statement of what the background of the first clause was describing. All of the choices except choice “it is even more basic for students to complete high school and attain at least a bachelor’s degree.” use this erroneous second conjunction (i.e. therefore, moreover, but, so), so they must be eliminated. Choice “it is even more basic for students to complete high school and attain at least a bachelor’s degree” is grammatically sound.
