when should a student writing a research - based paper directly quote a research text instead of paraphrasing or summarizing it?\no when the words quoted are specific and unique\no when the person quoted is an expert in his or her field\no when a paragraph does not yet have a direct quote\no when a summary or paraphrase would take too long to write
Answer
Brief Explanations:
Direct quotes are used when the original words are specific and unique, capturing a particular idea or expression that cannot be easily re - worded. Just being an expert doesn't necessarily mean direct quoting. Needing a quote in a paragraph for the sake of having one is not a valid reason. And length of summary/paraphrase isn't the main factor.
Answer:
when the words quoted are specific and unique
