Answer:
The statement he should include to best anticipate and respond to a counterclaim is:
C. While the school board may be concerned that an after-school computer lab would be too costly, the school could save money by asking local college students to work as volunteer tutors.
Step-by-step explanation:
Martell's claim is that the school should open an after-school lab so that students can use the computers to finish homework and projects that are computer based. A counterclaim to that will be a statement that presents a reason why creating the lab may be a bad idea. The counterclaim has to make sense, as well as Martell's response to it (the solution he offers to the counterclaim).
In letter A, the counterclaim is weak. It does not present a reason against the lab; it simply states there are people who disagree with it. We can eliminate this option.
Letter B does present a reason, but the problem is the response. It is subjective, personal. Martell would be basically attacking anyone who disagrees with him. Thus, we can also eliminate this option.
Letter C is the best option. It does present a reason - the lab could cost a lot of money - and a solution - finding volunteers to work in in. This is the choice Martell should make.
Letter D presents a response that has nothing to do with the counterclaim itself. It is also incorrect.
