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 1 presents Bernie Sanders' supportive stance on free college, while Sentence 2 raises a critical counterpoint. The transition word "however" clearly signals this contrast, improving the logical relationship between the opposing ideas. Other options fail: explaining tax burden does not connect the two ideas directly; "therefore" implies a cause-effect that does not exist; "and" suggests agreement, which is incorrect here.

Answer:

adding "however" to the beginning of the sentence.
