  1. Correct Answer: E

    Explanation:

    Skill: Managing word choice and grammatical relationships between words

    Explanation for Correct Answer E :

    Choice (E) is correct. It avoids the person shift error of the original by consistently maintaining the first-person “we” throughout the sentence.

    Explanation for Incorrect Answer A :

    Choice (A) involves a shift in person. The sentence begins with the second-person pronoun “you” but then switches for no apparent reason to the first-person “we.”

    Explanation for Incorrect Answer B :

    Choice (B) involves a shift in person. The sentence begins with the second-person pronoun “you” but then switches for no apparent reason to the first-person “we.”

    Explanation for Incorrect Answer C :

    Choice (C) involves a misplaced modifier. The prepositional phrase “with two eyes” should modify the verb “focus.” But with its placement after the noun “object,” the prepositional phrase modifies “object,” suggesting that the object itself has two eyes.

    Explanation for Incorrect Answer D :

    Choice (D) involves a shift in person. The sentence begins with the second-person pronoun “you” but then switches for no apparent reason to the first-person “we.”
