I was able to correctly chose (C), but I was tempted by (B) during the preptest. I'll try to break it down:
--if the info is of commercial/national-security value, it's dissemination needs to be restricted.
--if the destination is to current/future competitors/enemies, the dissemination of that type of info should be prohibited.
--but there must be free exchange of scientific info.
(A), (D), (E) can be quickly eliminated as they are required for the principle to follow.
(C) is irrelevant. We don't care if some research is more advanced in one country than another, we only care if they have commercial/national-security value. Besides, "basic scientific research" is just out of scope.
It took me a while to determine if (B) is relevant. but then I realized if the public have "detailed knowledge" of the country's advanced technology, the dissemination would already have been taken place. Am I right?
