A、Because they want to find the car there. B、Because they want to find evidence. C、Because they want to catch the thief there. D

After shopping for most of the day, a couple return to find their car has been stolen. They are shocked and very upset because they just bought it a month ago. They go to the police station to make a full report. Then, a police officer drives them back to the parking lot to see if any evidence can be found at the scene of the crime. To their surprise, the ear has been returned.
    There is an envelope stuck on the car with a note of apology and two tickets to a concert. The note reads," I apologize for taking your car, but my wife was having a baby and I had to use your car to rush her to the hospital. Please forgive the inconvenience. Here are two tickets for tonight’s concert."
     The couple feel relieved. After all, most human beings are kind, they think. They even feel glad that their car was used in such a way. It might perhaps have saved two lives, the mother’s and the baby’s. They go to the concert, enjoy the music to their hearts’ content, and return home late. To their astonishment, they find their house has been robbed. Valuable goods have been taken. The downstairs living room is in a mess. Even the kitchen is not spared. And, there is a note on the door reading, "Well, you still have your car. I have to put my newly-born kid through college somehow, don’t I?"
