Some people who live in the cities are very rich but some people have no home and no jobs-it's very sad. Your granddad likes it here (30) everyone talks about soccer. The Brazilians, (31) soccer team is one of the best in the world, all love soccer. We went to watch a match in a famous football stadium. Your granddad loved it. I preferred (32) all the countryside, which is so beautiful here and the animals. We've seen so many beautiful animals like (33) .
