Argument Breakdown:
First bold portion: "Walmart has recently begun transitioning from its traditional warehouse-based retail model to an online-first model."
This is background information establishing the context of Walmart's strategic shift.
Second bold portion: "whether this shift will lead to a reduction in the company's fixed costs"
This presents the specific question/issue that the argument will address.
Conclusion: "This is quite likely" (that fixed costs will reduce)
The argument's main claim.
Supporting Evidence: "since expenses such as warehouse rentals and in-store salaries have historically contributed significantly to Walmart's fixed costs."
This explains why the conclusion is likely true.
Evaluating the Options:
A. Incorrect - The second bold is not the central claim; it's the question being examined. The conclusion ("this is quite likely") is the central claim.
B. Incorrect - The first bold is not presenting an issue; it's providing context. The second bold is the issue itself, not evidence.
C. Incorrect - Neither bold portion is evidence; the evidence comes after both bold parts.
D. Correct -
First bold establishes the context (transition to online-first model)
Second bold identifies what's being predicted (whether fixed costs will reduce)
E. Incorrect - The first bold is not the subject of the conclusion; it's background context. The second bold is the subject being predicted.
Why (D) is Correct:
The first bold portion sets up the situation (context), while the second bold portion identifies exactly what the argument will make a prediction about (subject of prediction). The actual prediction ("this is quite likely") and evidence follow these two elements.
Answer: D
