A educator does his duty following the guidelines or by following his lessons learnt from his life , unless one can recognise there is importance of its own which is either known to human or not to everything in this essential to fulfill its own role in their own life, as we moulded own needs and greed and we name it evolution we just have to believe the laws of nature which are long learnt by every living being to protect nature, there is always a middle way to which dosent take take toll on both the sides that is very much acceptable to everyone
Here is another example of a simple error of omission that could have been caught if the student had read the essay aloud or given it to a friend to read. The word "of" should be between "calculation" and "the." That one small error makes the entire sentence awkward and confusing. If the instructor has to reread the sentence to try to understand its meaning, the flow of the essay is interrupted. If this happens often enough in the essay, it gives an overall bad impression on what otherwise might be a very good paper in terms of research.
