Weakening Question - To weaken the Board's Claim - we can either prove that
1) local drinking water is not polluted OR
2) material that caused the disease can affect the drinking water source.

(A) Strengthens the Board's Claim by affirming that there are other reasons for disease to occur and not because of the plant.
(B) Out of Scope as what happens in nearby community is not related to board's claim
(C) Correct Choice which suggests that the disease causing material is polluting the drinking wells.
(D) Unrelated to board's claim
(E) Strengthens the board's claim that some other pollutants cause the disease, not the one produced / used at plant.

Civic Leader : Disease is caused because of the material produced at plant
Board of Director : Disease is caused because of local wells that supply drinking water and NOT because of the plant
