Honghu, I do try to use the If x, then Y technique for logic CRs. In this example however, the biologist says 'If deforestation continues at its present pace, the Koala will become extinct'. He does not say 'If deforestation continues, the Koala will become extinct'. Given this, don't you think D is right.

The biologist didn't say what is gonna happen if deforestation does not continue at present pace (nonD). In other words, if it slows, E may or may not happen. Both cases would be consistent with his claim.

For the politician, he says if deforestation is stopped then E will not happen. He didn't say if deforestation is not stopped what is gonna happen. If deforestation is slowed, E may or may not happen. Both cases would be consistent with his claim.

In choice D deforestation is slowed, and E did not happen. Consistent with both people's claims.

D is consistent with the biologist's statement: "If the forest continues to disappear at its present pace, the koala will approach extinction.â€

I just edited my previous post with this bit below. Hope this helps.

If I am the politician and you told me that you slowed deforestation and that the koala survived, I can counter by saying

"I claimed that all one needs to do to save koalas is to stop deforestation. You claim that you saved koalas by slowing deforestation. But you still have not proved that koalas cannot be saved by stopping deforestation. By your own argument, if the koala can be saved by slowin, then its obvious that it can certainly be saved by stopping. What you are saying is in fact consistent with what I claim'

All we have to do for A is B. Meaning, B is sufficient for A.
In order to do A we have to do B. Meaning, B is necessary for A.

Do you see the difference?

Yes, I do see the difference.

However, the question asks for consistency (in other words, it does not contradict with the statements) and not for the same meaning and I therefore think that D stands.

But I may be wrong.

True. But you are insisting that D contradict the politician's claim.

Quote:
Which one of the following statements is consistent with the biologistâ€™s claim but not with the politicianâ€™s claim?

the answer choices are statements and not outcomes. I think that you've looked at the choices as if they were outcomes and not statements.
To test whether 2 statements are consistent, we should examine whether saying them together constitutes a contradiction.
Quote:
(B) Deforestation is stopped and the koala becomes extinct.

Now imagine the biologist saying this statement together with her first, would she be consistent?

Biologist: â€œIf the forest continues to disappear at its present pace, the koala will approach extinction,â€

Politician's only concern is to save koala.

There are two options, A & B, we have here which oppose politician's concern.

A certainly does not qualify to meet Biologist's concern. Therefore the answer is 'B'
