an essay or any form of writing on a subjuect must contain three parts...

even if headings are not given but logically it should contain introduction, main body where you give ur arguments and support them by examples etc ... and then in the end it should conclude... there should be a logcial developement of the essay where each part transcends to other logically... while one reaches conclusion all his questions are addressed and reader is left with no new questions after reading the essay... means eaasay shouldnot develop new questions in the mind of a reader

humble contribution if any one disagrees may educate me
