The author can show the character development
in many different ways. One of which is that the author must research about the
character's basic facts. For instance, if the character is a doctor, the writer must
read books related books, interview doctors etc. This method will also lead the
author to establish a well-written history of the character. The author must be
creative and make his character like a living person.
I am not sure what your options for this question are, but I can give you some pointers for the fallacy of hasty generalization that may help. Hasty generalization involves drawing a conclusion that is based upon a very small sample size, therefore using statistics in a faulty way and essentially jumping to conclusions. For example, you have a large population of, say, 1000 participants. You take a very small sample, of say 15 participants, from this population. You then draw all of your conclusions based on this small segment of the larger population. Hope this helps.
