The smaller the originality percentage the more original your paper. Quoting another author's words significantly increases your originality percentage and reduces your term paper score. A 0% originality score is as good as it gets. An excellent originality score is less than 10%. Scores in the range of 10% to 20% are acceptable. Scores greater than 20% will receive a zero for originality in the grading rubric.

ATT.:
A manned Mars expedition is good topic but extremely broad.  If you can narrow the focus it will make the paper easier to write. While writing keep in mind that this is an engineering ethics paper. One pitfall to avoid is spending too much of the paper describing the technology behind a manned Mars expedition and not enough on ethical issues and how they can be mitigated. Following the outline closely will help keep the paper balanced. Be sure to support your position with external references using one of the standard citation formats. Critical thinking and writing your own thoughts are the key to a successful paper.
