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.

Sentence 2 presents a contrast to the proposal in sentence 1: free college tuition may sound beneficial, but the writer argues it would increase taxes on the middle classes. Beginning sentence 2 with “however” makes that contrast clear. “Therefore” would suggest the tax burden follows logically from the proposal without signaling the opposing point, while “and” would only add information.
