Digital PSAT Reading and Writing Practice Question 105: Answer and Explanation

Question: 105

Whatever your preference, the method by which a product finds its way to you, the consumer, is logistics. Originally a term that described the flow of materiel for the military in the conflicts around the globe, it has now found its way into every element of consumerism. Major retailers have emerged that specialize in on-line shopping; others have outlet stores and websites where the buyer can choose a channel for procurement.

Which choice best states the function of the underlined phrase in the text as a whole?

• A. To define current usage of a phrase
• B. To address a likely reader objection
• C. To use primary source evidence
• D. To explain the root of a concept

Correct Answer: D

Explanation:

(D) The phrase is used to describe what the concept of logistics initially meant: it was a war term used to describe the delivery of ammunition. It is thus to explain the root of a concept, as in Choice (D). Choice (A) is flawed in that the phrase defines past, not current, usage of a phrase. There is no likely reader objection, as in Choice (B). To what would the reader possibly object? There is no primary source evidence provided, as in Choice (C).
