Hi @nivensdc,

C is incorrect because it doesn’t explain why the camel’s population would fall even more quickly after the testing range closed down. C tells us that unexploded bombs made the testing range still “somewhat” dangerous after the range closed. This could explain why the camel's population continued to fall after the range closed, however, it does not explain why the camel's population would fall even faster after the range closed then before it did. The unexploded bombs were there while the range was open too, so this could not cause an increase in the rate of camel deaths.

A, on the other hand, provides us with a reason why the camel population would decline even faster after the range closed. The bomb tests had kept out poachers and killed some camels. But, now the bomb tests are over, the poachers are coming in and killing even more camels then the bomb tests did.
