The only point of overlap seems to be under what circumstances chemical waste dump should be cleaned, the correct answer choice will invariably address this disagreement.
(A) This is unique to Alexander's argument and thus is not the point of issue, eliminate.
(B) This is unique to Alexander's argument, (that covering chemical waste dump site into woodland would be expensive)
(C) Neither discusses consulting the public. Teresa discusses the public in his premises insofar as their health is the town's top priority, this seems to misrepresent this contention, eliminate.
(D) Bingo. Alexander contends that the town should get rid of the dump site no matter what, however Teresa argues that it should do so only if the public health is in danger. If the public's health was in no danger, Teresa would obviously refuse but Alexander would say yes because it is important for us to redress the harm we've done to wildlife and woodland.
(E) Neither discusses destroying forests, they discuss under what conditions it is appropriate to destroy the dump site. eliminate.
