Hi there.
Sentence: The car salesman tried to beguile the customer with an offer of free gas for a year.
Hope it helps u.
Answer:
Cannot answer without seeing the excerpt and knowing title/author of work in question.
Explanation:
A verb is used to describe an action.
Example: Joan is running to the park to play frisbee.
The key words are: is running.
So, in your question, since Uncle Joe is growing a beard, that'll mean your verb tense is present progressive. It's present progressive because he's growing something, and things that grow have a process to follow through.
I hope I helped :)
