Complete Question Explanation
Must Be True. The correct answer choice is (B)
In this stimulus the environmentalist discusses the dangers of discarding appliances in poorly operated landfills, and those of incineration, because of the danger of cfc and heavy metal leakage (in the case of poorly operated landfills) or escape into the air by way of poison ash (in the case of incineration).
Answer choice (A): While this might be true, it is not discussed in the stimulus, so this answer choice fails the Fact Test and is incorrect.
Answer choice (B): This is the correct answer choice. If incinerated heavy metals can poison the ash and escape into the air, then this is not advisable.
Answer choice (C): Although CFCs are harmful in some way, they may be poisonous and have no effect on the atmosphere. Since the stimulus does not support this answer choice, it is incorrect.
Answer choice (D): The author discusses dangers associated with old appliances, but provides no information regarding new appliances, so this answer choice fails the Fact Test and is incorrect.
Answer choice (E): All we can say definitively based on the information in the stimulus is that old appliances should be kept out of poorly run landfills; the author specifically mentions that these pose no threats in landfills that are properly operated.
