GRE 機經 邏輯閱讀

Columnist: Until very recently, Presorbin and Veltrex, two medications used to block excess stomach acid, were both available only with a prescription written by a doctor. In an advertisement for Presorbin, its makers argue that Presorbin is superior on the grounds that doctors have written 200 million prescriptions for Presorbin, as compared to 100 million for Veltrex. It can be argued that the number of prescriptions written is never a worthwhile criterion for comparing the merits of medicines, but that the advertisement’s argument is absurd is quite adequately revealed by observing that Presorbin was available as a prescription medicine years before Veltrex was.

In the columnist’s argument, the two highlighted portions play which of the following roles?

1. The first is a claim that the columnist’s argument seeks to clarify; the second states a conclusion drawn about one possible interpretation of that claim.
2. The first identifies the conclusion of an argument that the columnist’s argument is directed against; the second states the main conclusion of the columnist’s argument.
3. The first states the main conclusion of the columnist’s argument; the second states a conclusion that the columnist draws in defending that conclusion against an objection.
4. The first identifies an assumption made in an argument that the columnist's argument is directed against; the second states the main conclusion of the columnist’s argument.
5. The first is a claim that has been offered as evidence to support a position that the columnist opposes; the second states the main conclusion of the columnist’s argument.

以下為自行作題檢討，如有疑問或錯誤歡迎討論

Columnist(專欄作家): 先確認是誰的意見 Until very recently, Presorbin and Veltrex, two medications used to block excess(過量, 過量的) stomach acid, were both available only with a prescription(處方藥) written by a doctor. In an advertisement for Presorbin, its makers argue(表達觀點) advertisement... argue 廣告聲稱，非 columnist 的意見 that Presorbin is superior(優越的) on the grounds that(在...的理由下) doctors have written 200 million prescriptions for Presorbin, as compared to 100 million for Veltrex. 

Presorbin is superior
是本句的主體，後面doctors have... 是對主體的觀點做證據支持，P is superior 是 conclusion，不是 evidence
doctors have written 200 million prescriptions for Presorbin, as compared to 100 million for Veltrex.
是對 P is superior 這個觀點支持的論據，而不是代表第一段highlight整句都是論據

It can be argued that the number of prescriptions written is never a worthwhile(值得的) criterion(標準) for comparing the merits(優點) of medicines, but that the advertisement’s argument is absurd(荒謬的)

but 轉折，代表第二句與第一句持相反論點

the advertisement’s argument is absurd
columnist 的 conclusion

is quite adequately(足夠的, 合格的) revealed(揭露) by observing(觀察, 遵守) that Presorbin was available as a prescription medicine years before Veltrex was.
