Expert opinions are based on factual evidence but differ from fact in that they are interpretations of
fact.The fact that experts
can draw different conclusions from the same information shows that opinions may not be as reliable
as facts or personal experience, but they are a useful and common means of supporting an argument.
In much of the argumentative writing you do, you will rely upon the opinions of experts in the field you
are studying both to determine your own perspective and to support your claims..
