Answer to last puzzle: "Swap camels." The will only stated that the one whose CAMEL finished last, not the rider!
That one was a personal favourite of mine! I first heard it a long time ago when I was in summer school taking an English course. I got too hung up over the "only two words" aspect of it to focus on the actual puzzle! Great job to those who got it!
You are on an island that is 1 km long and 1km wide, covered with nothing by dried, dead vegetation. Suddenly it catches fire at one end of the island and a strong wind is blowing it towards you rapidly, burning the whole width of the island. There's no beach, only sheer cliffs, and the sea is infested with sharks. What can you do?
