Solution

Sentence Analysis

Here’s the sentence structure:

  • Unlike the automobile company, (Comparison with the main subject)
    • whose research was based on crashes involving sport utility vehicles, (relative clause modifying ‘automobile company’. Subject: research; Verb: was based)
  • the research (Main Subject)
    • conducted by the insurance company (Verb-ed modifier modifying ‘the research’)
  • took into account such factors as a driver’s age, sex, and previous driving record. (Main Verb: ‘took into’)

The sentence intends to say that while the research done by the automobile company was based on crashes involving SUVs, the research done by the insurance company focused on a number of factors.

There is one glaring error in the sentence. It compares automobile company with the research. ‘Unlike’ has to be followed by research done by the automobile company since the main subject is the research done by the insurance company.

Option Analysis

(A) Incorrect. For the error explained above.

(B) Incorrect. Same error as in option A.

(C) Incorrect. Same error as in option A. Besides, the preposition ‘in its research of …’ modifies the main clause ‘the research conducted by the insurance company took…’, leading to a non-sensible meaning that the research conducted by the insurance company, in its research of crashes involving SUVs, took something into account.

(D) Incorrect. ‘having verb-ed’ form is called perfect participle. It is used to present the earlier action in a sequence of actions. The use of ‘having been based’ indicates that ‘based’ is an earlier action and that there is some later action. However, there is no later action for ‘automobile company’s research’. Thus, the use of ‘having verb-ed’ is incorrect here.

(E) Correct.
