Luke wrote a paper and used another person’s ideas and information. Instead of identifying the author, he wrote the information as if he were presenting his own ideas.

Which of the following did Luke do while writing his paper?
1. add paraphrasing
2. ommit plagiarism
3. include quotations
4. insert a citation

4. insert a citation

Based on the information provided, Luke did not insert a citation. Instead of properly identifying the author of the ideas and information he used, Luke wrote them as if they were his own. Therefore, options 3 and 4 (include quotations and insert a citation) can be eliminated.

The statement does not provide information about whether Luke added paraphrasing or omitted plagiarism. However, since he wrote the information as if he were presenting his own ideas, it implies that he did not properly paraphrase or avoid plagiarism.

So, the correct answer is:

2. omit plagiarism
