This is a subjective question, so there are certainly no "right" answers. Here are some close-examination strategies:
- Read the text through quickly, and then re-read more slowly until you feel that you understand what the text's purpose is and how each sentence contributes to a greater understanding.
- Highlight key words or phrases that show what the text's theme/topic/focus is.
- Examine the way information is presented. Is it scholarly, humorous, uncertain, etc?
- Is the text part of a larger work? If so, why is this excerpt significant? If not, then why is it meaningful standing alone?
- Research the author/person who created the text. Find out what drove them to write it or what they were trying to do.
- Is there a specific audience that the text is intended for? This relates to prior questions, but you could go deeper as well and look at how the text makes you feel, or whether you have learned a new way of thinking about something.
You can learn a lot by examining a text from different perspectives, including the typical characteristics of-- who, what, when, where, why, how?
Based on the given sentence above, the error that I can find is the incorrect use of the pronoun "their". Looking at the sentence, the subject is "One of your students", this means only one, and not all the students. Therefore, this should take a singular pronoun. So the correct sentence would be "One of your students left his or her book on the table." So the answer for this would be option A. Hope this helps.
A benefit of paraphrasing material from one of the sources would be that you can convey the message in a much simpler way than what is in your source. Also, you can easily convey what you had understood from the text you've read. Another would be that you avoid issues of plagiarism.
