The right answer is D.Lydia's argument:Premise: Each year, thousands of seabirds are injured when they become entangled in equipment owned by fishing companies.
Conclusion: Therefore, the fishing companies should assume responsibility for funding veterinary treatment for the injured birds.
Jonathan's argument:Premise: Treatment of the most seriously injured birds would inhumanely prolong the lives of animals no longer able to live in the wild, as all wildlife should.
Conclusion: Your proposal, however, should not be adopted.
Lydia concludes that fishing companies should assume responsibility for funding the veterinary treatment for the injured birds since thousands of these birds become entangled in equipment owned by fishing companies.
Jonathan, on the other hand, feels that Lydia's conclusion above should not be adopted. His decision is based on the premise that the treatment of the most seriously injured birds would inhumanely prolong the lives of animals no longer able to live in the wild as all wildlife should. From this premise, Jonathan is ignoring the possibility that some of the birds may not be seriously injured, hence treating them might restore them to a state where they are able to live their normal lives. Of course, it is possible that some of the birds might be severely injured that subjecting them to treatment might cause more harm to them than good when released into the wild after treatment. However, basing the rejection of Lydia's proposal on the premise that some birds may not benefit from veterinary treatment, Jonathan is unfair to other birds that might fully recover after treatment.
D states that Jonathan attempts to discredit her proposal by discussing its implications for only those birds that it serves least well, and this is line with the reasoning above.
The right answer is therefore D.(A) He directs a personal attack against her rather than addressing the argument she advances.
This is incorrect. Jonathan indeed made comments about the feelings of Lydia towards the birds, suggesting that her decision might not be objective but out of her feelings for the birds. But the crust of Jonathan's argument addressed the argument by countering her argument with the premise that treatment of the most seriously injured birds would inhumanely prolong the lives of animals no longer able to live in the wild, as all wildlife should. The validity of this argument relies on the assumption that most of the injuries sustained by the birds are very severe such that treatment does not restore them to states in which they are able to live in the wild as a wild animal should.
(B) He suggests that her proposal is based on self-interest rather than on real sympathy for the injured birds.
This is incorrect for the same reasoning ascribed to A above.
(C) He questions the appropriateness of interfering with wildlife in any way, even if the goal of the interference is to help.
This is incorrect. Jonathan does not question the appropriateness of interfering with wildlife in any way. The only problem with his argument is that it can be flawed if most of the birds that get entangled in the equipment owned by the fishing companies sustain injuries that can be treated in order to restore the birds to a state where they can live in the wild as any other wild animal.
(E) He evades discussion of her proposal by raising the issue of whether her feelings about the birds are justified.
E is incorrect based on the same reasoning ascribed to A and B above.
