It is often argued that women have a right to control their own reproductive capacity and that abortion is a vital tool for doing this. Proponents of this view state that nobody has the right to force a woman to undergo a nine month pregnancy, with all the accompanying discomfort and serious health risks, if she does not want to. Some say that the right to abortion is absolute and it is acceptable to use it as a method of birth control; other pro-choice advocates disagree but believe it should be available in cases where pregnancy will endanger the woman's health, the fetus has a severe congenital defect or the pregnancy resulted from rape or incest.
The function of an argumentative essay is to show that your assertion (opinion, theory, hypothesis) about some phenomenon or phenomena is correct or more truthful than others'. The art of argumentation is not an easy skill to acquire. Many people might think that if one simply has an opinion, one can argue it successfully, and these folks are always surprised when others don't agree with them because their logic seems so correct. Argumentative writing is the act of forming reasons, making inductions, drawing conclusions, and applying them to the case in discussion; the operation of inferring propositions, not known or admitted as true, from facts or principles known, admitted, or proved to be true. It clearly explains the process of your reasoning from the known or assumed to the unknown. Without doing this you do not have an argument, you have only an assertion, an essay that is just your unsubstantiated opinion.
