Which choice completes the text so that it conforms to the conventions of Standard English?
film Successfully
film successfully
film; successfully
film, successfully
Correct Answer: D
Choice D is the best answer. The comma correctly sets off the adverbial participial phrase "successfully cementing..." which modifies the action of the main clause.
Choice A is incorrect because of the capitalization error and lack of punctuation. Choice B is incorrect because punctuation is needed to separate the modifier. Choice C is incorrect because a semicolon cannot precede a dependent phrase.
