Question

read the passage from an argumentative essay. (1) bernie sanders has argued that no one should have to pay tuition to go to college. (2) this will only increase the tax burden on the middle classes. to improve the relationship between ideas, the writer should revise sentence 2 by explaining the concept of a tax burden. adding \however\ to the beginning of the sentence. placing \therefore\ at the beginning of the sentence. connecting it to the preceding sentence with \and\.

Explanation:

Sentence 2 directly results from the claim in sentence 1: if no one pays college tuition, the tax burden on the middle class rises. "Therefore" is a conjunctive adverb that clearly signals this causal/result relationship, making the logical connection explicit. The other options either introduce unrelated context (explaining tax burden), use a word that doesn't fit the logic (however contradicts the link), or create a grammatically awkward connection (and is too weak for this causal flow).

Answer:

C. placing "therefore" at the beginning of the sentence.
