Stout pretty much means strong. When added to the word brave, it's clear that "our hearts" face fear head on, with a strong, unfearing willpower.
One of the themes is that the author want his readers to know that there is more to life then we can see, or that a building/ strengthening a friendship is worth more than any treasure. Another one is like don't judge a book by its cover in this case the author is trying to point out when gandalf said that biblo is more than what meets the eye and thorin and co. underestimated him. Until he found the ring. Sorry if this is spoiling the book to anyone. Hope this helps! Have a great day!

3. Architect - work on designing buildings, which fits the criteria.
4. Likely a lawyer because they are easier for rich clients to get, and they are of course in court fighting for their clients.
to show you can fight the claim, disprove it with facts you have found during your research.
