DISCUSSION: This is also another specific question. Pay attention to the tone of the answer choices: all of them seem to contain an opinion. If you understood the author’s stance on deep-well injections, this question should be easy.
The author thinks that deep well injections have become riskier and more controversial, as more people have started relying on underground drinking water. See the end of paragraph 1.
___________
- CORRECT. The second last sentence of paragraph 1 states this.
- The passage doesn’t mention illnesses, so we shouldn’t infer that. It’s easy to make a mistake here since your background knowledge might be telling you that ingesting toxic waste would make you sick.
- Newly developed alternatives weren’t mentioned. Eliminate. You may be thinking of the start of paragraph 1: companies are moving away from landfills and incinerators and towards deep well injections. The problem, landfills and incinerators are not new solutions. They are old solutions that have newly become more expensive due to regulation.
- The passage doesn’t mention public awareness of environmental issues and how that relates to acceptance of deep-well injections. And the end of paragraph 1 says that deep well injections have become more controversial!
- It hasn’t been more widely accepted. See the end of paragraph 1: deep well injections have become more controversial.
