 V/ (1,5 points) Read the following passage then answer the questions. Write your answers on the answer sheet.             As a result of years of research, we know that too much animal fat is bad for our health. For example, Americans eat a lot of meat and only a small amount of grains, fruit and vegetables. Because of their diet, they have high rates of cancer and heart disease. In Japan, in contrast, people eat large amounts of grains and very little meat. The Japanese also have low rates of cancer and heart disease. In fact the Japanese live longer than anyone else in the world. Unfortunately, when people move to the US, the rates of heart disease and cancer increase as their diet changes. Moreover, as hamburgers, ice-cream, and other high fat food become popular in Japan, the rates of heart disease and cancer are increasing there as well. People are also eating more meat and dairy products in other countries such as Cuba, Mauritius and Hungary. Not surprisingly, the disease rates in these countries are increasing along with the change in diet. Consequently, doctors everywhere advise people to eat more grains, fruit and vegetables and to eat less meat and fewer dairy products.
