Read the passage and answer the following question:

In earlier times, when every substance was believed to have its own qualities, there was no difficulty in believing that some substances were endowed with life, others not. Wood was wood, and water was water, and though transformations did occur, as in the disappearance of wood in the fire, they were not surprising in a world where the most miraculous changes were taking place under everyone’s every day. There was nothing but ‘doth suffer a sea-change into something rich and strange’. A seed put into the ground became in a short time a plant with leaves and flowers: the white and yolk of an egg turned into the flesh and bones and feathers of a chicken, which, no sooner was the shell cracked, jumped out and started running about.
