A good question to ask her is:
When did she start writing?
What gave her the idea to write her book?
What is her favorite place to write?
How does she sit still long enough to write (That's something I can't do for more than a few minutes, so I'd like to know!)
You're right, it's D! "Everybody 'seems' excited today because both a lawyer and a doctor are here."
I believe the answer would be Bill Gates. An appositive is a noun that renames a noun right beside it. In this case, "Bill Gates" is renaming "One of the richest men in the world."
Religion gives people something to believe in, provides a sense of structure and typically offers a group of people to connect with over similar beliefs.
The answer to your question would be option B. Hope this helps you and enjoy the rest of your day :)
