V.Read the passage and give short  answer (ONLY ONE WORD for each answer) 
The average life span of the Japanese is 78 for males and 85 for females, the longest in the world. The main secret lies in their food. The Japanese eat a lot of tofu, which is made from soybeans. Tofu contains lots of vegetable protein, calcium and vitamin B. It doesn’t contain much fat and it doesn’t provide many calories. Seafood like fish and vegetables play an important role in their diet, too. They cook the seafood with less cooking oil and less time. For each meal, they have more dishes on the table than us but they eat only a little of everything, never stuffing themselves. Japanese people also work very hard and do more exercises. This helps them burn the calories off easily
