How could a writer best revise this sentence to avoid overly formal language? a. by inserting an adverb between the two parts of the infinitive b. by switching from active voice to passive voice. c. by choosing to end the sentence in a preposition d. by switching from passive voice to active voice

By choosing to end the sentence in a preposition.

Explanation:

The best revision in the sentence could be the change in a preposition in order to avoid formal language that may provide an excessively sophisticated and complex. The employment of formal language often lessens the personal touch in the work. Thus in order to avoid this, the preposition could be replaced and the relative pronoun could be erased in informal language. Hence, the revised sentence would be as following:

"She didn't have the container to put the leftovers in."

Probably by switching from third person to 1st the writer would avoid using an overly formal language
