As a way of reconciling these two facts, scientists have hypothesized that nearly all of the oxygen being produced was taken up by iron on Earth’s surface. Clearly, however, this explanation is inadequate. New studies show that the amount of iron on Earth’s surface was not sufficient to absorb anywhere near as much oxygen as was being produced. Therefore, something in addition to the iron on Earth’s surface must have absorbed much of the oxygen produced by plant life. In the argument given, the two portions in boldface play which of the following roles? A. The first is a claim made by the argument in support of a certain position; the second is that position. B. The first is a judgment made by the argument about a certain explanation; the second is that explanation. C. The first expresses the argument’s dismissal of an objection to the position it seeks to establish; the second is that position. D. The first sums up the argument’s position with regard to a certain hypothesis; the second provi
