Read the text about the Siberian tiger and match the fact with its evidence.

The Siberian Tiger
The Siberian tiger is the biggest tiger in the world. The Siberian tiger is more than three meters long. Its tail is one meter long. It weighs up to 320 kg. It lives in forests in the north. Winter in these forests is very long and cold, which lasts for 8 months with the temperature reaching -40 and there is a lot of snow. Yuck, I don’t like winters and snowy weather. But the forests are a good place for the tiger to live, because they are very big and there are not many people.
Tigers are very strong and can walk many kilometers every night looking for food. They eat big forest animals such as deer, bears and wild board, fish and rabbits. Tigers eat a lot of meat. They eat 27 kilograms of meat in one night.
Mother tigers usually have three or four babies. The babies live with their mothers when they are young. When they are two years old, they find a place in the forests to live. I think it is so cruel to leave their babies to live on their own at the age of two. Anyway, they are the most unusual creatures in the animal kingdom.
