Let's look at the argument. Alexander is arguing that the chemical waste dump should be cleaned up immediately regardless of the cost as we have a pressing obligation to redress the harm done to local forests and wildlife. Teresa responds by saying that the town's first priority is people's health, so there is no need to clean up the dump unless it presents a significant hazard to people.
Teresa's statement conforms to which of the following principles:
(A) Environmental destruction should be redressed only if it is in the economic interest of the community to do so.
Incorrect. T is saying it should only be redressed if it presents a health hazard to the people regardless of the economic considerations.
(B) Resources should be allocated only to satisfy goals that have the highest priority.
Correct. T argues that the first priority is people's health, and no resources should be allocated to the cleanup unless it presents a severe health hazard. ~ highest priority -> ~ resources
(C) No expense should be spared in protecting the community's health.
Incorrect. T argues that the health is the first priority but she never goes that far as to say that no expense should be spared to protect it.
(D) Environmental hazards that pose slight health risks to people should be rectified if the technology is available to do so.
Incorrect. Out of scope. T only says that hazards must be remedied if they pose a significant health risk, we cannot infer any opinion on slight health risks or technology.
(E) It is the community as a whole that should evaluate the importance of eliminating various perceived threats to public health.
Incorrect. Out of scope. T never talks about who should make this decision whether to clean up the dump or not.
