  1. Correct Answer: B

    Explanation:

    Skill: Understanding the content, form, and function of sentences

    Explanation for Correct Answer B :

    Choice (B) is correct. “Feasible” means possible. If one were to insert this term into the text, the sentence would read “Marine biologist Sylvia Earle makes a career of expanding the limits of deep-sea mobility, making hitherto impossible tasks feasible through the new technology designed by her company.” The comma suggests that the second part of the sentence will elaborate on how Earle “expanded the limits of deep-sea mobility.” The reference to “new technology” supports the idea that Earle made impossible goals “feasible,” or possible.

    Explanation for Incorrect Answer A :

    Choice (A) is incorrect. “Famous” means well known. If one were to insert this term into the text, the sentence would read “Marine biologist Sylvia Earle makes a career of expanding the limits of deep-sea mobility, making hitherto impossible tasks famous through the new technology designed by her company.” While Earle’s work may have gained recognition, the term “hitherto” implies that previously impossible tasks are now possible, not just “famous.”

    Explanation for Incorrect Answer C :

    Choice (C) is incorrect. “Fantastic” means unbelievable or excellent. If one were to insert this term into the text, the sentence would read “Marine biologist Sylvia Earle makes a career of expanding the limits of deep-sea mobility, making hitherto impossible tasks fantastic through the new technology designed by her company.” It may be said that Earle made “fantastic” advances in deep-sea mobility, but it is somewhat illogical to say that previously impossible tasks are now unbelievable or excellent.

    Explanation for Incorrect Answer D :

    Choice (D) is incorrect. “Controversial” means subject to dispute. If one were to insert this term into the text, the sentence would read “Marine biologist Sylvia Earle makes a career of expanding the limits of deep-sea mobility, making hitherto impossible tasks controversial through the new technology designed by her company.” The sentence provides no support for the claim that Earle’s accomplishments were at all “controversial.”

    Explanation for Incorrect Answer E :

    Choice (E) is incorrect. “Captivating” means enthralling or charming. If one were to insert this term into the text, the sentence would read “Marine biologist Sylvia Earle makes a career of expanding the limits of deep-sea mobility, making hitherto impossible tasks captivating through the new technology designed by her company.” It makes little sense to claim that advances in marine biology made previously unachievable projects charming.
