6. Прочитайте текст и решите, какие предложения правильные (T), а какие неверные (F).

The grandmother didn't want to go to Florida. She wanted to visit some of her family in east Tennessee and she was seizing every chance to change Bailey's mind. Bailey was her son she lived with, her only son. He was sitting on the edge of his chair at the table, bent over the orange sports section of the Journal. "Now look here, Bailey," she said, "see here, read this," and she stood with one hand on her thin hip and the other rattling the newspaper at his bald head- Bailey didn't look up from his reading so she wheeled around then and faced the children's mother; a young woman in slacks, whose face was broad and innocent as a cabbage and was tied with a green handkerchief that had two points on the top like rabbit's ears. She was sitting on the sofa, feeding the baby apricots out of a jar. "The children have been to Florida before," the old lady said. "You all ought to take them somewhere else for a change so they would see different parts of the world and be broad. They have never been to east Tennessee." The children's mother didn't seem to hear her but the eight-year-old boy, John Wesley, a stocky child with glasses, said, "If you don't want to go to Florida, why don't you stay at home." He and the little girl, June Star, were reading the funny papers on the floor.
