Answer:
A. Condense the author's idea into a shortened version but in your own words
Explanation:
D. Take an author's idea word for word from the text is plagiarism, unless you are are quoting. C. Rewriting the author's idea in your own words in a version that is about the same length is paraphrasing. A. is the definition of summarize. When someone asks you to "sum up" a story, they are asking you to give you a shorter version of the story with only the most important parts. Paraphrasing and summarizing sound pretty similar, but the key difference is in length. A paraphrase should be about the same length as the original idea, summarizing should be shorter. B. is also wrong, since you are <em>expanding </em>upon the author's thoughts, when summarizing tries to condense them.
