Answer choice (e)

@Boram, Happy to help! The argument begins by providing us with some context (many environmentalists hold that the natural environment is morally valuable for its own sake, regardless of any benefits it provides us) before diving into the premises. Beginning with "however," we're introduced to the argument. The ethicist says that even if nature has no moral value, nature can be regarded as worth preserving because it's beautiful. This is a premise. The beginning of the next sentence is another premise, and the ethicist says that it's disputable whether nature is morally valuable but undeniable that it's beautiful. The author then concludes that because of this, an argument for preserving nature that emphasizes nature's beauty will be less vulnerable to logical objections than one that emphasizes its moral value. The question stem asks us to choose the answer that displays a principle that the ethicist's reasoning most closely conforms to in the stimulus. From our analysis above, we know that the ethicist is basically saying that if an argument for preserving nature focuses on something that is indisputable (nature's beauty) rather than something that is debatable (the moral value of nature), then it will be less vulnerable to logical objection. Answer A is incorrect because the conclusion is not that any argument in favor of preserving nature will be less open to logical objection; the conclusion is that one argument in favor of preserving nature (nature's beauty) will be less open to logical objection than another (the moral value of nature). Answer B is incorrect because it does not match the structure of the argument we outlined above. Answer C is incorrect because its conclusion (that nature would be more clearly worth preserving if it did not have a disputable characteristic) does not match the argument's conclusion that one argument in favor of preserving nature (nature's beauty) will be less open to logical objection than another (the moral value of nature). Answer D is incorrect because does not come close to matching the argument. It doesn't have anything to deal with one argument (nature's beauty) being less open to logical objections than another argument (the moral value of nature). Answer E is correct, as it accurately matches the argument structure we outlined above. E's premises (if an argument for preserving nature appeals to a characteristic that can be regarded as a basis for preserving nature and that philosophically indisputably belongs to nature) and E's conclusion (an argument for preserving nature will be less open to logical objections) are a perfect match with our analysis of the ethicist's argument. This is our answer choice. Does this make sense? Let us know if you have any more questions!
