After each exercise there is also a link to read further about the paragraph and I always try to find a good documentary video from youtube based on the topic of the paragraph. Sometimes it's hard to find good videos. I am hoping you will not just learn how to unscramble paragraphs (which is not a skill you'll ever need in life :P) but you'll also learn more about the world.
Someone e-mailed me and asked me why I didn't explain how to solve each paragraph. To be honest with you, I think you will learn more about solving these exercises if *you* analyze your mistakes and understand how the sentences logically connect to each other.
(Interestingly, historians have re-examined Hamilton and Burr and are now more sympathetic to Burr. Burr was actually a very progressive thinker who opposed slavery and favored women's rights. Many historians have also pointed out that Hamilton continually provoked Burr in the press by writing false information about him. Both men contributed to the early USA - indeed, Burr was an amazing war hero during the Revolution who saved the life of his commanding officer at the risk of his own life. Burr received a bad reputation in US history because of his duel with Hamilton and because Thomas Jefferson later turned against Burr and attempted to have him jailed on false 'treason' charges.)
Yes, I'm the guy who created the scandal in Asia awhile ago. I felt that the Korean performers I was teaching were not being treated up to acceptable standards, and I reported this to a Korean newspaper to help ensure that, in the future, performers would be treated better.
