The Wonderful Wizard of OzPassage AWhen Dorothy stood in the doorway and looked around, she could see nothing but the great gray prairie on every side. Not a tree nor a house broke the broad sweep of at country that reached to the edge of the sky in all directions. The sun had baked the plowed land into a gray mass, with little cracks running through it. Even the grass was not green, for the sun had burned the tops of the long blades until they were the same gray color to be seen everywhere. Once the house had been painted, but the sun blistered the paint and the rains washed it away, and now the house was as dull and gray as everything else.Passage BThe road was smooth and well paved, now, and the country about was beautiful, so that the travelers rejoiced in leaving the forest far behind, and with it the many dangers they had met in its gloomy shades. Once more they could see fences built beside the road; but these were painted green, and when they came to a small house, in which a farmer evidently lived, that also was painted green. They passed by several of these houses during the afternoon, and sometimes people came to the doors and looked at them as if they would like to ask questions; but no one came near them nor spoke to them because of the great Lion, of which they were very much afraid. The people were all dressed in clothing of lovely emerald-green color and wore peaked hats like those of the Munchkins.Questions :1- What is the most common color of the area around Dorothys home?2-What is the most common color of the surroundings in this passage?3-What do you think the author is trying to say about the differences in these two places?
