Hi Powerscore!
So I eliminated all answers except for B and D and I ended up choosing the wrong answer even though my gut told me it was D. It was because I couldn't eliminate B and B made a bit of sense.
Here's my thought process.
I thought that "Something is not the cause of a problem" refers to the tourist industry and how the stimulus may be proving that the tourist industry is not the cause of the excessive development of seaside areas by stating that they "would never knowingly do anything to damage the industry." I thought that when the answer choice says "never coexist" I thought it meant something along the lines of "The tourist industry won't let it happen."
Upon further thought, I know why D is correct. I just don't know how to eliminate B. So how is B eliminated and also, how can I avoid making this mistake of misinterpretation again?
