The common errors in this summary of Margaret Atwood's "The Handmaid's Tale" are:
- The author's first name is used (choice a)
- It is written with contractions (choice b)
The use of the author's first name is not appropriate when writing about literature, as it is more formal to use the author's last name or a pronoun such as "she" or "her." The use of contractions is also not appropriate when writing about literature, as it can be more formal and objective to write in standard English without contractions. It is not an error to write about a story in the first person or in the past tense, as these are common narrative perspectives and tenses in literature.
