• Read the passage below and choose one correct answer for each question:

            After spending a day at the beach, I stopped to buy a snack on my way home. But
  when I reached for my wallet, it wasn’t there. I checked my other pockets, and the car and then headed back to look at the beach. My driver’s license, my ID card - my mind was racing through all the things I had lost and I felt rotten. A search of the beach and parking lot proved fruitless, so I headed home. I tried to forget it because there was nothing I could do, but I was mad at myself for losing it. After dinner when I was watching TV and trying to forget, the phone rang and a voice asked: “Did you lose a wallet? I found it on the beach”. What a great feeling that gave me - not only for my luck, but also for my faith in all humanity!
