Unlike the body styles of the Boeing 747 and other Everett-built jets, ideal for long flights, the Boeing 737 has a cost-effective body style, consuming less fuel over medium-range distances.


the question is illogically comparing body styles with the Boeing 737!!!!

A. the body styles of the Boeing 747 and other Everett-built jets,
B. the body styles of the Boeing 747 and other Everett-built jets, which are
C. the Boeing 747 and other Everett-built jets in having body styles- gramatically awkward sentence!

Option A, B and E incorrectly compares the Boeing 737 with the body styles of the Boeing 747 and other EB jets. Option C distorts the meaning by using in having.... So, option D is correct

A. the body styles of the Boeing 747 and other Everett-built jets, - Incorrect comparison as above.

A. the body styles of the Boeing 747 and other Everett-built jets,
Incorrect.
This option is comparing "body styles of..." with "Boeing 737" which is incorrect. Comparison should be between Boeing 747/Everett-built jets and Boeing 737


B. the body styles of the Boeing 747 and other Everett-built jets, which are
Incorrect.
Same as option A.


C. the Boeing 747 and other Everett-built jets in having body styles
Incorrect.
"In having body styles" makes the construction of the sentence awkward. Option D is clearly the best choice.


D. the Boeing 747 and other Everett-built jets, whose body styles are
Correct.
Comparison has been drawn correctly.


E. those of the Boeing 747 and other Everett-built jets with body styles
Incorrect.
Unlike "those" of? Not clear what those of is - probably body. This is an incorrect comparison - should be between Boeing 747/Everett-built jets and Boeing 737

Re: Pack 5 Q1: Unlike the body styles of the Boeing 747... [#permalink]
The sentence uses the structure Unlike X ..., Y ... One needs to make sure that X and Y are comparable things. The non-underlined portion of the sentence says "the Boeing 737 has ... ", so the underlined portion should talk about planes. Thus, options (A), (B), and (E) are out. Between (C) and (D), the latter is correct because it uses a proper pronoun "whose" to refer to the two types of the planes.

Unlike requires Noun to Noun comparison. Looking at the non-underlined portion, we have Boeing 737 so we are comparing one boeing to other or to other jets.

A. the body styles of the Boeing 747 and other Everett-built jets,
This option suggests the comparison between body styles and Boeing 737. We require same or similar comparisons. Jets compared with body styles is not the correct comparison.

This option suggests the comparison between body styles and Boeing 737. We require same or similar comparisons. Jets compared with body styles is not the correct comparison.

this option has distorted comparison. Unlike the jets in having body styles, the Boeing 737 . It compares jets in having body styles with Boeing. Comparison could have been Jets in having <non cost effective> body styles with Boeing that has cost effective body styles.

D. the Boeing 747 and other Everett-built jets, whose body styles are
Comparison is between Boeing/Jets with Jets ; over their body styles; looks fine. Whose can refer to plural form, that's good as well!

E. those of the Boeing 747 and other Everett-built jets with body styles
we have unclear reference for 'those' in this option, hence comparison elements cannot be clearly determined.
also it produces a run on sentence. those of Boeign 747 and other Jets with body styles Boeing 737

D looks good!

We need something after "Unlike" comparable (grammatically & logically) to "Boeing 737", so A, B, and E are out.

- correct choice. Relative pronoun "whose" can modify both animate and inanimate nouns on GMAT.

Official Explanation:

Unlike the body styles of the Boeing 747 and other Everett-built jets, ideal for long flights, the Boeing 737 has a cost-effective body style, consuming less fuel over medium-range distances.

A. the body styles of the Boeing 747 and other Everett-built jets,
B. the body styles of the Boeing 747 and other Everett-built jets, which are
C. the Boeing 747 and other Everett-built jets in having body styles
D. the Boeing 747 and other Everett-built jets, whose body styles are
E. those of the Boeing 747 and other Everett-built jets with body styles

A quick review of our answer choices shows a split in how we start this phrase (the body styles or the Boeing 747). There are also differences in how the clause transitions into the next clause (whose, which, with, in having).

Since the first word of the sentence is not underlined, it is important that we pay attention to it, because it will often heavily affect how we evaluate our answers. The first word is “unlike.” This immediately tells us that this sentence is a comparison, and we must compare like items. We need to look at the non-underlined portion of the sentence to see what we are comparing. “The Boeing 737” is the noun being compared with the noun that will follow “unlike.” The Boeing-737 is a plane so we need to compare it to another plane. Options A and B compare the body style of some planes to an actual plane. We can either compare body styles or planes, and the part of the sentence that doesn’t change dictates that we are comparing planes. Options A and B cannot be the correct answers.

Option E gives us a sentence that would read “Unlike those of the Boeing 747 and other Everett-built jets with body styles ideal for long flights, the Boeing 737 has a . . .” Those what? It doesn’t tell us. This comparison is nonsensical. Option E cannot be the correct answer.

It might be tempting to look at the “whose” that is modifying an inanimate object and immediately rule it out. But not so fast! Since English has no possessive pronoun for inanimate objects, “whose” can be used with living things and non-living things. While people will often rewrite a sentence to avoid using “whose” with something inanimate, it is not necessarily incorrect. Before we decide “whose” can’t be the answer, let’s look at Option C to see if it has any issues.

Option C reads “Unlike the Boeing 747 and other Everett-built jets in having body styles ideal for long flights, the Boeing 737 has a cost-effective body style.” That doesn’t really make sense, and even if it did, this construction is incredibly awkward. “In having” is just not the best way to transition in this sentence, and there are few situations where a preposition and a gerund work smoothly together. Option C cannot be the best answer.

Option D, even though it uses “whose” with something non-living, is concise, makes sense, and is grammatical. Option D is the best answer.

D. the Boeing 747 and other Everett-built jets, whose body styles are
E. those of the Boeing 747 and other Everett-built jets with body styles


Correct answer: D

A: Incorrect because it creates an incorrect comparison between "the body styles ..." and "the Boeing 737."
B: Incorrect for the same reason as (A).
C: Incorrect because of the prepositional phrase "in having." "In having" suggests that the Boeing 737 has "body styles ideal for long flights." However, the meaning of the sentence is that the Boeing 737 is different from those planes that have such body styles. Hence, (C) creates a meaning distortion.
D: Correct.
E: Incorrect for the same reason as (A) and (B). (E) also attributes "body styles" to the Boeing 737, rather than to the Boeing 747 and other Everett-built jets.

Unlike the body styles of the Boeing 747 and other Everett-built jets, ideal for long flights, the Boeing 737 has a cost-effective body style, consuming less fuel over medium-range distances.
a) "ideal for long flights" is acting as a modifier. So, we can ignore it
b) For a correct comparison, the right answer choice should correctly compare with "the Boeing 737"

A. the body styles of the Boeing 747 and other Everett-built jets,
B. the body styles of the Boeing 747 and other Everett-built jets, which are
E. those of the Boeing 747 and other Everett-built jets with body styles
A, B and E are out because all of them have the wrong comparison structure

C. the Boeing 747 and other Everett-built jets in having body styles
1st part is right but "in having body styles" OMG! Clearly wrong

D. the Boeing 747 and other Everett-built jets , whose body styles are
Everthing is correct here.
a) clear comparison
b) right modifier
