Do you think cloning human beings should be allowed? Why? Why not?

Readers should understand what the issue is and what is at stake. The issue must be arguable, as noted above. After stating your thesis, you will need to discuss the issue in depth so that your reader will understand the problem fully.

A clear position taken by the writer. In your thesis sentence, state what your position is. You do not need to say: I believe that we should financially support the space station. Using the first person weakens your argument. Say funding for the space station is imperative to maintain Americas competitive edge in the global economy. The thesis can be modified elsewhere in the essay if you need to qualify your position, but avoid hedging in your thesis.

A convincing argument. An argumentative essay does not merely assert an opinion; it presents an argument, and that argument must be backed up by data that persuades readers that the opinion is valid. This data consists of facts, statistics, the testimony of others through personal interviews and questionnaires or through articles and books, and examples. The writer of an argumentative essay should seek to use educated sources that are unbiased, and to use them fairly. It is therefore best to avoid using hate groups as a source, although you can use them briefly as an example of the seriousness of the problem. Talk shows fall into the same category as they are frequently opinionated or untrue.

A reasonable tone. Assume that your reader will disagree with you or be skeptical. It is important, therefore, that your tone be reasonable, professional, and trustworthy. By anticipating objections and making concessions, you inspire confidence and show your good will.
