what is the book "FREAKONOMICS" about? (20 MARKS)

Overview
The book is a collection of economic articles written by Levitt, translated into prose meant for a wide audience. Levitt had already gained a reputation in academia for applying economic theory to diverse topics usually not covered by "traditional" economists (note that Levitt is actually not at all a "rogue" economist in that he entirely accepts the standard microeconomic paradigm of rational utility-maximization; he is merely applying it to unconventional subjects).
topics include:

Chapter 1: Discovering cheating as applied to teachers and sumo wrestlers (See below)
Chapter 2: Information control as applied to the Ku Klux Klan and real-estate agents
Chapter 3: The economics of drug dealing, including the surprisingly low wages and abject working conditions of crack cocaine dealers
Chapter 4: The controversial role legalized abortion has played in reducing crime. (Levitt explored this topic in an earlier paper entitled "The Impact of Legalized Abortion on Crime.")
Chapter 5: The negligible effects of good parenting on education (instead, the authors assert that it is what the parents are, not what they do, that makes a difference)
Chapter 6: The socioeconomic patterns of naming children
