Personally, I can't imagine any one particular portion being more important than the other as the construction of a logical argument throughout an essay depends heavily on each phase.
Without a strong introduction, it's hard to build any sense of direction or garner interest.
Without a solid body, it's impossible to make your point.
The lack of a conclusion is also detrimental since the finish is just as important as any other part because it's what leaves the lasting impression.



And something tells me I'm late for this poll by...a few.....weeks...That said, I think it is about time that I return to my state of hibernation.
