Option D is the correct answer.
Let's understand the information mentioned in the passage before trying to answer the question.
So the passage starts by telling us that "Walmart has recently begun transitioning from its traditional warehouse-based retail model to an online-first model". Then tells us what is expected of this strategy i.e. "A question has arisen about whether this shift will lead to a reduction in the company’s fixed costs. This is quite likely, since expenses such as warehouse rentals and in-store salaries have historically contributed significantly to Walmart’s fixed costs"
Now it asks us the role played by both the boldface in the passage.
Let's look at the options as see which of them correctly tell us the role of both boldface.
Option A: "The first introduces the context for the argument; the second is the central claim the argument attempts to justify". The first part of the option is correct in some part but the second part of the option which says that the second boldface is the claim that argument attempt to justify is wrong because the second boldface is about prediction regarding the plan mentioned in the first boldface so this is incorrect.
EliminatedOption B: "The first presents an issue that the argument seeks to evaluate; the second provides evidence in support of a prediction made in the argument". This option is wrong as it says that the second boldface provides evidence in support for the first boldface which is incorrect the role of the second boldface is telling us what is expected of the strategy discussed in the first boldface.
EliminatedOption C: "Both the first and the second provide evidence in support of the main claim". This option is incorrect both the boldface does not support the main claim the role of the first boldface highlights a strategy followed by Walmart which the passage then tried to evaluate on the basis of second boldface.
EliminatedOption D: "The first establishes the context for the argument's evaluation; the second identifies the subject of that prediction". This option is absolutely the roles which both the boldface play, as the first boldface tells us about a strategy that Walmart is implementing, which is later on evaluated then the second boldface plays a role of the subject on the basis of which this strategy is evaluated. This is the absolute fit for the roles played by both the boldface but let's check Option E as well before marking our answer.
SelectedOption E: "The first identifies the subject of the main conclusion; the second provides evidence supporting that conclusion". The second boldface does not support the first boldface, it provides a criteria on which the argument is evaluating the strategy mentioned in first boldface.
EliminatedSo after reading and checking all the option we can finally conclude that only Option D tells us the correct role played by both the boldface.Bunuel
Walmart has recently begun transitioning from its traditional warehouse-based retail model to an online-first model. A question has arisen about
whether this shift will lead to a reduction in the company’s fixed costs. This is quite likely, since expenses such as warehouse rentals and in-store salaries have historically contributed significantly to Walmart’s fixed costs.

A. The first introduces the context for the argument; the second is the central claim the argument attempts to justify.
B. The first presents an issue that the argument seeks to evaluate; the second provides evidence in support of a prediction made in the argument.
C. Both the first and the second provide evidence in support of the main claim.
