I found this in Articles; it's useful. However I had to read it 3 or 4 times to figure out what was being said because of the typos. I'm used to decoding ordinary posts, but I think articles could benefit from a little editing. It took me a while to recognize that "send" was "second". I think Pan's computer hiccuped and dropped two letters. The other misspelled words are easily recognizable. I think it should be clarified which bag is the first and which is the second. Which is inside the other, and why? If the bags have different ratings, you get different results if you change which one is "first" in the equation.
