"One time I had an ovarian cyst and had to go to the hospital. I had no one to watch my 1-year-old son so I had to bring him with me. I was crying really hard because I couldn’t get my son to sit still with me and he kept trying to pull on my tubes. I just broke down. My phone was dead so I couldn’t call anyone. One of the nurses came up to me in my room and asked me if it was alright if she tried to calm my son down and give me a break. She brought some toys and a blanket back for him, and she held him in her arms and played with him so that I could calm down until my mother-in-law showed up. I didn’t even get her name, but it was so meaningful that she would show enough compassion to help us. Angels are REAL."
A. Preposition: over; object of the preposition: bridge
A preposition shows the location of an object, it shows where something is. In this case the preposition is "over" as that is the only word that is showing 'where' something is and thus the car becomes the object.
