Destination: Come one, come all, as we take a trip back in time! It is called Petrified Forest because of the petrified wood all over the park from the trees. Today, we will go back to when they formed- the late Triassic period! The Triassic period began 252 years ago and ended 201 years ago and is the beginning of the Mesozoic period. Petrified wood formed around 225 years ago, almost at the end of the period. There were a lot of changes happening during the Triassic period. It began with extinction which caused the main animals of the time to be reptiles, and the continents were beginning to shift. Pangea, the supercontinent, was still around at the beginning of this period, but by the middle of it, the continent split off into Gondwana in the south and Laurasia in the north. The climate was mostly hot and dry before the…

Three persons P1, P2, and P3 were invited by their friend F to make some smørbrød (sandwich made of bread, eggs, and tomato) together. To make a portion of smørbrød, three ingredients are needed: a slice of bread, a slice of tomato, and a slice of an egg. Each of these persons P1, P2, P3 has only one type of each of the ingredients: person P1 has slices of bread person P2 has slices of tomato; person P3 has slices of egg. We assume that persons P1, P2, and P3 each has an unlimited supply of these ingredients (i.e., slices of bread, slices of tomato, slices of egg), respectively. Their friend F, who invited them, also has an unlimited supply of all the ingredients. Here is what happens: the host F puts two random ingredients on the table. Then the invited person who has the third ingredient picks up these other two ingredients, and makes the smørbrød (i.e., takes a slice of bread, puts on it a slice of tomato, and puts on top a slice of egg), and then eats the smørbrød. The host of…
