1. "Remember that you should always develop a thesis statement before you begin writing an essay. An introduction must have a thesis sentence and you cannot write an intro without one. A thesis statement is one sentence that perfectly summarizes the purpose of your essay. For instance, if your subject is the government in India, your thesis statement may be something like, ""In India, the Prime Minister is the most important figure in government."" see: https://en.wikipedia.org/wiki/Government_of_India
Defending and explaining that one statement would be the purpose of your essay—and every essay needs a purpose. So, before you begin to write an introduction, develop a thesis."
