Split #1: the comparison. The intent of the sentence is to compare Dorn Consulting to comparable consulting firms.
The construction "Dorn Consulting handles much more sophisticated issues than comparable consulting firms" is ambiguous --- does it mean that Dorn handles both sophisticated issue and comparable consulting firms? That's not the intent.
We need to make clear that "comparable consulting firms" are parallel to the subject, Dorn, not the object, issues.
To do this, we need to include a verb to show that the other firms are a subject.
We could repeat the verb "handle," or replace the predicate with the universal verb "do." Choices (A) & (B) have no verb, so they are incorrect.
Split #2: Dorn Consulting is a company, a collective noun, so it is singular. It may have many employees, but the company itself is singular. Notice it takes a singular verb at the beginning of the sentence. It also requires a singular pronoun: choices (A) & (D) make the classic GMAT mistake of using a plural pronoun for a singular collective noun; both of those choices are incorrect.
Split #3: the constructions "less percentage" and "fewer percentage" are incorrect. The correct construction is "a lower percentage", and of the five answer choices, only (C) gets this correct.
The answer is (C).FAQ: How do you know when to use "less" and when to use "lower"?
A: We can't think about one word applying to percentages at all times. Instead, we need to think about the structure of the sentence and what, exactly, is being described as less or lower.
Let's consider some examples:
- The workforce is 50% less than that of the previous year.
- There were 50% fewer people in the workforce this year than last year.
- The number of people in the workforce was 50% lower than the previous year.
All three of these deal with the same main idea, but the actual structure of the sentences is different.
When we are talking about countable nouns (like 'the number of people' or even just 'people'), we use a comparison word ending in -er, like lower or fewer. When we refer to an uncountable noun or a statistic (like 'the workforce'), we use the word less.
This confusion between words (especially in the case of "less" vs "fewer") is an ongoing struggle for many, many people... even native speakers of English with advanced education!
