Some help on Mark Twain, please?

Mark Twain commented on society through the use of satire. That means he took something he thought was silly or funny and took it to the extreme in one of his characters or books so that people could recognize it as ridiculous. He was able to take current political personalities in his lifetime and use them to base characters on so that his writing was always a reflection of modern politics, but almost always a funny satirical version of events. He was able to comment on slavery in books like Huckleberry Finn in which he depicts the life of a slave but really made people think about the institution of slavery without preaching to them. In The Prince and the Pauper, he depicted two boys who look exactly alike, but how different their lives are simply because one was poor and one rich. It was a great commentary on the struggles of the poor, but maybe even a nod to the unique (but certainly less life-threatening) struggles unique to the wealthy or famous. He was incredibly popular with the public during his lifetime, but also with those in power.
