OFFICIAL EXPLANATION
B
This is basically an idiom question, but your checklist may first uncover a pronoun issue. The pronoun
it clearly refers back to
light bulb, but in this case the pronoun isn’t actually necessary:
Edison’s miraculous invention refers directly back to
light bulb without the need of a pronoun. This eliminates choices A and D, both of which are actually run-on sentences. Next, you should turn your attention to the end of the underlined phrase. Do you have an invention
to use energy (choices A and E), an invention
that uses energy (choices B and D), or an invention
using energy (choice C)? If you said
that uses, then you are doing just fine. Since we’ve already eliminated choice D,
the best answer is B.
