Can somebody help me out on writing 3 paragraphs on some kind of argument?

I think that the link below could be very helpful to you in the
process of composition.  I would say that being able to understand a particular topic is going to
be critical.  You have to figure out what you want to write about and upon what topic you have
some level of passion or zeal.  The notion of an argumentative essay is something that will
require you to have an argument that needs to be developed.  You might have to do some reflection
on what it is you really hold some beliefs.  Perhaps, there is some legislation that government
has passed that you are really not comfortable with or something of which you are in zealous
support.  This might be a starting point.  There might be a practice that you think should be
stopped or expanded.  This could serve as another point of commencement for your writing.  In the
end, you will have to identify what instigates the sense of passion within you that will compel
you to write or articulate strong points of view in order to compose the argumentative
essay.
