Good questions. First, you're correct that animal refuges are not necessarily created by international efforts--but here is the author's argument:
premise: Animals are becoming extinct at an increasing rate.
conclusion: International efforts to help the animals have been wasted.
With all else equal, the fact that animal refuges have actually saved species from extinction would at least weaken the author's argument that efforts on behalf of the animals are all wasted.
As for your second question, the answer choice specifies that species have been saved from extinction by animal refuges--this implies protection rather than simple relocation/habitat substitution.
One other point: It's always great to be able to look at an answer choice and know for sure that it is correct, but that is not always possible; it is often easier to identify the wrong answer choices as incorrect.
I hope that's helpful--please let me know whether this all makes sense--thanks!
