Read the following extract, and answer the questions that follow: I will arise and go now, and go to Innisfree, And a small cabin build there, of clay and wattles made; Nine bean rows will I have there, a hive for the honey-bee, And live alone in the bee-loud glade. And I shall have some peace there, for peace comes dropping slow, Dropping from the veils of the morning to where the cricket sings; There midnight's all a glimmer, and noon a purple glow, And evening full of the linnet's wings. (a) What image has been used to describe peace? (b) What are the living creatures mentioned in the poem?
