The demanding nature of this assignment has earned it some nicknames such as five legged monster, a hamburger essay, one three one essay, a three-tier essay, etc. 'One three one' is a significant term, as it aptly describes the structure of the essay.
An introduction, three main paragraphs and a conclusion. This kind of assignments are usually to compare and contrast essay topics, or process analysis topics, where you need to put in some rational thought to give a conclusive comment regarding the topic. For example: 'Women Leaders: a blessing for the society'. Here you will have some or the other personal perception regarding the issue, however, a rational and logical comment or comments by you, that summarize all the aspects of leadership, have to be included.
How to Write it?
Though such essays are rarely, expository or informative essay topics, including a good flow of facts is an absolute necessity. This makes them tough to write, since you need to club argumentative topics with informative ones. The three principle dimensions of these essays are research, thought, and flow. These three dimensions have to go simultaneously, and hence start typing the entire thing in a soft copy, as it becomes easy to maneuver within the river of facts, and also makes it easier for you to edit the written matter.
The first part is of course the introduction. It is more of a defining paragraph, where the entire concept is stated in a very crisp manner. Some historically significant events or names and statements related to thinkers and philosophers can be included. Unraveling of the topic should be done in this paragraph. Every topic is like a mathematical explanation. That is, you have to solve the literary equation and find out what actually is to be written.
As per the above example, 'Women Leadership: a blessing to the society', it should contain some integral thought regarding the high social standing of women in the modern society, and their highly capable temperaments. These thoughts should be nothing but truth and truth itself, one cannot make an illogical personal comment or statement. Back your argument with some research on the web, findings by the government, research papers, etc.
Main Body #1
The next part is a deeper view in the prospective, and in this paragraph you need to state some facts. There should be the rational explanations of both the three factions of the issue ― women leaders, government, and the society in general. Remember that you need to logically and rationally state facts in an ascending sequence. Statistics, success stories, and the society's appreciation of women leaders in the past and even some negative stories of failure can be included.
Main Body #2
The second part of the main body is a bit difficult to write, as you are commenting upon different aspects. Here, with respect to the same example, you will have to come up with simple logic such as how 99% of females are ideal mothers, and how every mom is a great leader. The simpler the logic, more authentic the fact becomes. This part is difficult due to the fact that, you need to state logic within the flow of language. Your own logic and thought thus play a highly integral part.
Main Body #3
You will have to, however, write an example in the same analogy of the second paragraph. For example, Hilary Clinton is not just a great leader, but is an ideal mother, and who possesses pinnacle high tolerance and undeniably high volumes of compassion. In manners, she is an ideal mother, a woman, and a leader.
Have you heard of Schaffer paragraph? It's a kind of paragraph where four factions are included ― a topic statement, a detail, and commentary followed by the finalization. Writing the conclusion in this manner would be great, as it will thoroughly summarize the said aspects of the entire essay.
It is recommended to abstain from using a template, as it puts your own thoughts into darkness. Taking some writing tips into consideration will help a lot.
