UPS Trucks (A) CORRECT
(B) Modifier (that are powered by gasoline)
(C) Modifier (that will run on … natural gas); Meaning / Idiom (converting … that)
(D) Meaning
(E) Meaning; Modifier (that are powered by gasoline)
First glanceThree answer choices start with
to convert or
on converting, while the other two mention convert to at the end. When parts of the sentence move around across the answer choices, look out for Meaning, Modifier, or Structure issues.
Issues(1) Meaning
Meaning / Idiom: converting … that
Choices (A), (B), and (C) begin with to convert or on converting, while (D) and (E) use to convert at the end of the underlined section. Temporarily ignore the modifiers in each answer choice and look for the simple sentence structure. Here is the core structure of each sentence:
(A) The UPS plans to convert its trucks to run on natural gas.
(B) The UPS plans to convert its trucks to run on natural gas.
(C) The UPS plans on converting its trucks that will run on natural gas.
(D) The UPS plans for its trucks to convert to run on natural gas.
(E) The UPS plans that its trucks will convert to run on natural gas.
In choices (A), (B), and (C), the UPS is clearly doing both the planning and the converting. However, in choices (D) and (E), convert comes after trucks, rather than coming after United Parcel Service. This illogically implies that the trucks will convert themselves of their own accord, rather than being converted by the UPS. Eliminate answer choices (D) and (E).
Choice (C) says that the organization plans to convert just the trucks that will (already) run on natural gas. First, this wording never indicates what the organization plans to convert the trucks to. Second, if you assume (from knowledge of the original sentence) that it plans to convert the trucks to natural gas, then this reasoning is circular; logically, you can’t convert to natural gas the trucks that already will run on natural gas. Eliminate choice (C).
(2) Modifiers: that are powered by gasoline; that will run on … natural gasThree of the answer choices use the term gasoline-powered trucks. The other two choices, (B) and (E), change this modifier to that are powered by gasoline. In choices (B) and (E), the modifier is moved away from the noun trucks, and appears immediately after the noun area. Since the modifier is immediately after the word area, it seems to imply that the area, not the trucks, is powered by gasoline. Eliminate choices (B) and (E).
Also, the intended meaning of the sentence is that only the gasoline-powered trucks in the area—as opposed to all trucks in the area—will be converted. By moving the reference to gasoline power away from the word trucks, choices (B) and (E) create ambiguity. It is no longer immediately clear whether the sentence refers to all trucks in the Los Angeles area or only the gasoline-powered ones.
Answer choice (C) also uses a that modifier. In this answer choice, the that modifier starts at the end of the underlined section: that will run on cleaner-burning natural gas. As in choices (B) and (E), this modifier logically describes the trucks, but is incorrectly placed next to the word area. Eliminate answer choice (C).
The Correct AnswerCorrect answer (A) makes clear that the
trucks are
gasoline-powered. It also clearly conveys the fact that the UPS does both the planning and the conversion.
