In Chapter 12 of "The Adventures of Tom Sawyer", what did Mark Twain mean when he said, "Tom?

Gravity is synonymous with grave or serious. It could just mean he started cracking up or smiling a little bit from a very serious demeanor. I gotta go read the book again :P.

Excellent! Must have read the book more than twice but never noticed the gravity of this sentence. 'Looked with such understanding that it conveyed true seriousness of what he wanted to know/convey.

Yes, "gravity" is used in this case to mean "seriousness". So the sentence could be rewritten to say "Tom looked up at her face, and a slight smile peeked through his serious attitude. " However, the way Mark Twain wrote it was much more poetic!

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
