"All that is needed to save the koala is to stop deforestation"...
How would you write it as conditionality?
.
SAVE KOALA --> DEFORESTATION......? (Since ALL indicates sufficiency whereas IS indicates necessity)
.

I am getting confused because of this LR question where I need to pick an answer choice that contradicts the statement written above. The correct answer is "deforestation is stopped and the koala becomes extinct", which is not a negation but a contrapositive of "SAVE KOALA --> DEFORESTATION". How can it be a contradiction when it is just a mere restatement of the stimulus?

This is from PT2.S2.Q11

Thank you in advance
