Giúp mình lựa chọn đáp án trong đoạn văn này: An odd thing happened to me two weeks ago. It was on Saturday morning, our classmates decided to go for a drive. We prepared a picnic lunch and planned to spend a day in the countryside. Unfortunately , on the way we had some engine trouble. There were no garages to have our car repaired.
