What does george's conversation with slim reveal about his past treatment of and present feelings toward lennie?

Georges conversation reveals that Lennie was adopted and George would take care of him. His present feelings are that he feels bound to take care of him as he is kinda like a brother.

The details about the statues, i believe, are that they're carved from blocks of igneous stone, many of them are partially buried under the ground which to preserve and protect them from the harsh environment on easter island, and many of the facial features have washed away. also, the most well-preserved one is at the british museum in london.these are just guesses from what i can see and what i think i read correctly. i'm sorry i couldn't be more .
