[bulldoser]

Could someone please explain why answer A is correct? I ultimately chose C due to the last sentence of the passage that said "Unfortunately, as societies produce more toxic waste, industry will rely increasingly upon this relatively cheap, efficient means of disposal."

While I understand that the passage itself was arguing that the use of deep-well injection had many risks but the last sentence seems to concede that it's not going away. So I picked C because it referenced the cheapness of deep-well injection. Any help would be greatly appreciated!

One problem with that answer, bulldoser, is that the passage says nothing about any newly developed alternatives. It's just deep well injection that is discussed, nothing more recently developed. Thus, despite what that last line said about expense, we cannot say that answer C is true "according to the passage." That question type means that the answer will be found directly in the text! Answer A is there in the first paragraph, making it the only valid choice.
