Passage Four
You have been badly injured in a car accident. It is necessary to give you a blood transfusion because you lost a great deal of blood in the accident. However, special care must be taken in selecting new blood for you. If the blood is too different from your own, the transfusion could kill you.
There are four basic types of blood; A, B, AB and O. A simple test can indicate a person’s blood type. Everybody is born with one of these four types of blood. Blood type, like hair color and height, is inherited from parents.

My uncle was the oldest at 72 years old, but he was still strong. My cousin at that time was 10 years old, and I was 25 years old. All of us liked hunting. Usually we went hunting on the weekend, especially in winter, because winter is the hunting season.
On the 25th of January, we decided to go hunting. All things were ready in the car, a Range Rover with four-wheel drive. We began on Thursday afternoon, and it took us three hours by car. We reached the place we were looking for at 5: 15 P.M.. First, we fixed the tent, then we made coffee and had a few minutes of rest. After that, we left to go on the hunt. We hunted using a falcon. Often, we hunt birds and rabbits. We spent two hours without finding anything. We decided to go back to the camp. On our way back, my cousin saw
