If I had taken this exam I would have raised hell with LSAC.
Why is A the right answer? So okay FINE the oil company rep can NOT have more than one motive for cleaning up. His motive is PURELY for wildlife preservation and in fact he HATES oil, is ANGRY at BP and Exxon and is going to go join an anti-pat terrorist legion to wage doom on anyone using anything fuel oriented to save the world. Hell its Ralph Nader and Bonos love child why not?
This would not make the environmentalist's argument stand at all.
So A doesn't cut it exactly. What am a I missing here?
