Assignment:
Professor Lee is writing a proposal for a research grant, and the deadline for the proposal submission is two days from now. To complete the background section of the proposal, Lee copies a few isolated sentences of a journal paper written by another author. The copied sentences consist of brief, factual, one-sentence summaries of earlier articles closely related to the proposal, descriptions of basic concepts from textbooks, and definitions of standard mathematical notations. None of these ideas is due to the other author. Lee adds a one-sentence summary of the journal paper and cites it.
Does the copying of a few isolated sentences in this case constitute plagiarism?
By citing the journal paper, has Lee given proper credit to the other author?
Two to three paragraphs in your own words to help me understand, please.
