The correct answers are B. While tablets are expensive, most buyers can save money in the long run by purchasing e-textbooks instead of print books and D.However, the amount of money districts spend on paper used for copies, which tablets would largely replace, balances the implementation cost.
Step-by-step explanation:
A counterclaim is an argument or statement that shows another argument might be not valid, in this case, the counterclaim is about the high cost of replacing tablets instead of textbooks, this statement needs to be rebutted or disproved with evidence that shows how replacing tablets is not as expensive as the opponents are trying to show. As a result, both options B and d are logical and strong rebuttals considering option B. "While tablets are expensive, most buyers can save money in the long run by purchasing e-textbooks instead of print books." shows, in the long run, the cost of tablets is lower than the cost of textbooks that proves to say this would be really expensive might not be true. Similarly, in option D "However, the amount of money districts spend on paper used for copies, which tablets would largely replace, balances the implementation cost" proves the counterclaim is not valid because the district spends a lot of money on copies that tablets can replace thus, the cost might be the same. In this way, both options B and D are appropriate rebuttals because they prove the cost of replacing books for tablets is not as high as the opposition claims that is the main purpose of rebuttals.
