Your stuck on and island and you can only bring 3 things. What would you bring?
a boat, a plane, and a space ship. wait, i just re-read the question, and now i realize that it says i'm already on the island, and i can bring 3 things, presumably somewhere else. so then i will take a plant sample, and sand sample, and a rock sample. unless there is treasure in which case i would take the treasure instead
