Answer: The green Jeep will be driven on the road trip.
Explanation: The passive voice is formed by using a form of the auxiliary verb "to be" followed by the past participle of the main verb. In this sentence, the auxiliary verb is "will be," the past participle of the main verb "drive" is "driven," and the object of the original sentence (the green Jeep) becomes the subject of the new sentence. This construction allows the sentence to focus on the green Jeep rather than the person who will be driving it.
