Hey Appletree,
So this is a great question. And you may already know this, but I always like to reiterate this in the more difficult must be true (most strongly supported) questions in reading comp: they are asking which answer choice is the most strongly supported out of the five, not which answer is definitively true.
But I do think the sentence you point outsupports answer choice C. I will post it here for the other students who view this in the future: "Although systematic empirical studies are lacking, experience shows that harmful pollutants constantly cross most international borders, and that nations have only rarely attempted to remedy this situation."
This was considered a principle by the author in previous sentences, and it has been "rarely" even been attempted to be remedied. The first sentence in paragraph 3 also supports this answer choice.
I don't think this answer choice is by any means 100% certainly true, but based on the passage, I'd give it an 80-90% chance of being true, which is higher than the remaining 4 answer choices, making this answer choice the most strongly supported.
I hope this helps, and I wish you all of the luck in your studies.
Best,
Ryan
