LOL
you guys are funny
so i googled it before checking your replies, because i knew i was reaching by implying there was a length requirement.
but the fact of the matter is that the average PHD "dissertation" at least a hundred pages long.
but yall can go ahead and keep arguing about syntax and what not
maybe theres some gramatical or spelling errors in my posts you can pick apart as well. 
Yes, the PhD dissertation is that long. But that is one paper out of the many you write in a doctoral program. Not every paper you write is 100 pages, you idiot. When writing a paper for a class, professors want brevity. You're talking about one paper. Many people in PhD programs also publish in peer reviewed journals. These papers tend to be maybe 8-15 pages in length.
And often, many of the PhD pages are devoted to graphs, questionnaires, etc. Sometimes graphs and questionnaires, and references can take up 20+ pages. So 100 pages of a dissertation is not 100 pages of writing. So you may have 60-70 pages in writing, and 20-30 including references, graphs, questionnaires.
So in conclusion, when you take the whole thing into consideration, most papers still require brevity, besides the dissertation.
Basically, youre still wrong and stupid.
