The book Gulliver's Travels contains four parts. What does each part deal with?
A. The first part tells about Gulliver’s experience in Lilliput where the inhabitants are six inches tall, twelve times smaller than the normal human beings. In the second part, Gulliver is left alone in Brobdingnag where people are ten times taller and larger than ordinary human being, and superior in wisdom.
B. The third part deals with Gulliver’s accidental visit to the Flying Island where the philosophers and projectors devote all their time and energy to the study of some absurd problems. The last part is a most interesting account of his discoveries in the Houyhnhnm Land.
