So let me offer some words of advice now, as you head into the weekend without your last summary returned to you, an omission I will rectify Monday. You are guilty of distortion when you change the original material. In context of the summary, that loss seemed to refer to the debate. The difference may be slight, but it's a misrepresentation in any case. Your job in a summary is to represent the source.
Misrepresentation is distortion.
You are guilty of plagiarism in a range of instances from grand to slight. But easy as they are to spot, they are also easy enough to avoid for you a writer. Quote only when the original phrasing is beyond paraphrasing or when it uses language particularly succinctly and aply. Less obvious but still plagiarism is pulling ideas, particularly interpretations, from a source, even if in your own words, without citing those ideas as someone else's. When information recurs from work to work, basic stuff like the date of Lincoln's birth, the date of the first radio broadcast, you won't need to cite it.
