I believe the answer you are looking for would be the second answer choice, "We read Shakespeare's tragedy, <em>Othello</em>, after reading two of his comedies."
This is because when information already speaking of something mentioned, is referred to to clarify a subject, it must be separated by commas. (that's how I remember)
ex: My mother, the queen, is placing a new law down to make everyone have equal rights.
ex: Today I went to Ms. Green's, the principal's, office.
We sit by the pool and read books
Answer:
<em>A. the unborn daughter whom her mother lost in the circus disaster</em>
Explanation:
I would say that this is right. If the person decided to send their money to a person who needed it then that alone is a wonderful thing to do. As for the fact that the sender did not include his/her name, they might not want recognition or praise for their actions. Many people decide to donate anonymously because they want to help the cause without getting involved personally.
Hope this helps!
