Grandma Moses is among the most famous twentieth－century painters of the United States， ye
Grandma Moses is among the most famous twentieth-century painters of the United States， yet she had only just begun painting in her late seventies. As she once said of herself： “I would never sit back in a rocking-chair， waiting for someone to help me.” She was born on a farm in New York State. At twelve she left home and was in a service until at twenty-seven， she married Thomas Moses， the tenant of hers. They farmed most of their lives. She had ten children， of whom five survived; her husband died in 1928. Grandma Moses painted a little as a child and made embroidery pictures as a hobby， but only changed to oils in old age because her hands had become too stiff to sew and she wanted to keep busy and pass the time. Her pictures were first sold at an exhibition， and were soon noticed by a businessman who bought everything she painted. Three of the pictures were shown in the Museum of Modern Art， and in 1940 she had her first exhibition in New York. Between the 1930‘s and her death she produced some 2，000 pictures： careful and lively pictures of the country life she had known， with a wonderful sense of color and form. Which of the following would be the best title for the passage? A.Grandma Moses B.The Children of Grandma Moses C.Grandma Moses： Her Best Pictures D.Grandma Moses and Her First Exhibition From Grandma Moses‘ s words of herself in the first paragraph， it can be inferred that she was _______.A.independent B.pretty C.rich D.alone Grandma Moses began to paint because she wanted to _______.A.make her home beautiful B.keep active C.improve her salary D.gain an international fame Grandma Moses spent most of their life ________.A.nursing B.painting C.farming D.embroidering 请帮忙给出每个问题的正确答案和分析，谢谢！
