(A) Deforestation continues and the koala becomes extinct.

Is it B ?

There could be other reasons for why the Koala can become extinct.
All we know for sure is that declining forests will lead the Koala
to extinction.

Jay,Would you please explain why its B.
B is inconsistent with the politicians claim but how it is consistent with biologists claim.
According to Biologists if the forest disappears in the same rate,koala will approach extiction.
Now B says Deforestation is stopped but koala becomes extinct.Please explain

The answer is D

In biologist's claim: rate of deforestation = to rate extinction of koala.
Answer D agrees to that. fullfilled one requirement

In politicial's claim: stop deforestation and save the koala, but accroding to answer D we are saving the koala by reducing the rate of deforestation. Hence we are disagreeing with the politicial.

B says if deforestation is not stopped, the koala will become extinct.
It does not say if deforestation is stopped, the koala will not become extinct.

There is a distinction between these two statements.

Thus, B is consistent w/ the Biologist's claims.
