How is an essay structured?
In order for your essay to be convincing and make sense, it needs to be presented inside a well structured piece of writing. How do you do this within the framework of an essay's general structure of Introduction,Body, Conclusion? Firstly, you need to be clear about what elements you should include within these three sections of an essay. The table below outlines these elements.
|Introduction|| General statement or orientation to topic|
Brief summary of the main topics/arguments/points made in the essay
These sentences support, expand or explain the point made in the topic sentence
|Conclusion||Restatement or summary of the main points made in the body paragraphs and a final comment (if appropriate)|
You also need to be clear about the function of each of these essay sections.

In Chapter 3 of The Little Schemer, the answer to the question of why we don't simplify the rember function right away is "because then a function's structure does not coincide with its argument's structure." I'm having trouble understanding what a function's structure is, what an argument's structure is, and what the difference is between them.
Here's the unsimplified version:
And here's the simplified:
From what I can tell, the main difference is that the function has gone from two conds asking one question each to one cond asking two questions.
The function's arguments are the atom "a" and the list "lat."
This is the first time, outside of the densely written foreword, where the book references the word "structure." In my mind, the definition of the word "structure" so far is open to interpretation.
Someone has asked this exact question here before, but I have trouble following the answer. Why does a two-cond structure coincide or not coincide with the structure of a list? A list, in my mind, doesn't have any conditions at all!
Isn't a condition equivalent to a question in Scheme? Perhaps I'm misunderstanding what a condition is, which could be a reasonable root of my frustration. Anyways, any clarification on this would be very much appreciated! Thank you!
