Reading the passage
Two developments need to stay separate: industry is increasingly using this method because it is cheap, and the method has become controversial as more communities rely on underground drinking water. Increased use doesn't mean increased public approval. We need an answer whose change and explanation both match the account.
Working the answers
- ACorrect
The first paragraph directly links the controversy to “growing numbers of communities” relying on underground drinking water. More dependence on those supplies makes the possibility of contamination a pressing concern.
- B
The author describes a threat to a water supply and possible dangerous exposure. We aren't told that toxin-related illnesses have increased near injection sites or that such an increase caused the controversy.
- C
The alternatives mentioned are landfills and incinerators, not newly developed technologies. Their rising costs help explain industry's choices, but C adds a claim about new alternatives and wider acceptance that we weren't given.
- D
Increasing public environmental awareness isn't identified as a cause of acceptance. The stated reason for industry's growing reliance is the method's relatively low cost and efficiency.
- E
We aren't told that high toxicity has made the method more widely accepted. The fact that the waste is hazardous helps explain the concern about contamination; it doesn't establish public approval of this disposal method.
