Teacher: In this task, you're given a text which is the body of the document. Indicate your answer as "Yes" if the text is about a person, otherwise indicate your answer as "No". Don't generate anything else apart from "Yes" or "No". Pay attention that for your answer to be "Yes", the passage should be generally about a person. Mentions of people in the text don't necessarily mean the text is about a person.
Teacher: Now, understand the problem? If you are still confused, see the following example:
Text: The third and current HMS Argyll is a Type 23 'Duke' Class frigate. She is currently the oldest serving Type 23 frigate in the Royal Navy. Like all of her class she is named for a British dukedom in this case that of Argyll.
Solution: No
Reason: HMS Argyll is a frigate which a warship. Clearly the text is not about a person. Hence, the answer is No.

Now, solve this instance: Text: Nathaniel Wales was an American businessman and politician from the Commonwealth of Massachusetts. A Republican.
