GMAT Verbal: Sentence Correction Example Problem #6

Problem:

In contrast to large steel plants that take iron ore through all the steps needed to produce several different kinds of steel, processing steel scrap into a specialized group of products has enabled small mills to put capital into new technology and remain economically viable.

(A) processing steel scrap into a specialized group of products has enabled small mills to put capital into new technology and remain
(B) processing steel scrap into a specialized group of products has enabled small mills to put capital into new technology, remaining
(C) the processing of steel scrap into a specialized group of products has enabled small mills to put capital into new technology, remaining
(D) small mills, by processing steel scrap into a specialized group of products, have been able to put capital into new technology and remain
(E) small mills, by processing steel scrap into a specialized group of products, have been able to put capital into new technology and remained

Solution:

Grammar Rule tested! Illogical comparisons

The major concept tested in this question is illogical comparisons.  The original sentence is comparing large steel plants to processing steel scrap.  In the same way that it would be illogical to compare Beethoven’s symphonies to Mozart (the composer), it is illogical to compare large steel plants and a method of processing steel scrap.  Instead, you should compare large steel plants to small steel mills.  Eliminate answer choices (A) , (B) , and (C) , since they all compare large steel plants to processing steel scrap.

Tip! Always compare the same type of thing (books to books and people to people). You cannot logically compare a book to a person!

Now we are left with choices (D) and (E). The only difference between these two choices is the final verb: “remain” vs. “remained.”

Tip! In correct answers, all verbs are in the same tense.

Let’s take a look at the verb in the non-underlined portion of the sentence, “take.”  Since “take” is in the present tense,  all of the other verbs in the corrected sentence must also be in the present tense.  In both (D) and (E), “have been able” is in the present perfect, which is also a present tense, however, only choice (D) keeps all of the verbs in the present tense by using “remain.”  Therefore, (D) is the correct answer.
