Input: Consider Input: Billy had a pet turtle that he took good care of, everyday. His turtle's name was Tumble. Tumble liked to walk around outside in the garden and dig small holes to sleep in. Billy loved Tumble and would visit him outside when he got home from school. Tumble's favorite food was oatmeal. So, every day after school, Billy would make Tumble a big bowl of oatmeal and take it outside for Tumble to enjoy. Tumble would see Billy and walk up to him as fast as a turtle can go. Billy would put the bowl down and wait for Tumble to come up to the bowl to eat from it. When Tumble reached the bowl, he put his nose on it. But, the oatmeal was too hot to eat. Billy reached down and blew on the hot oatmeal, to cool it down for Tumble to eat. Once the oatmeal was cool enough, Tumble could dig in and eat his big bowl of oatmeal. Billy loved to watch as Tumble ate his bowl of oatmeal, because Billy took good care of Tumble, everyday. <sep>What were some of Tumble's favorite things?<sep>He loved digging holes in the garden and oatmeal

Input: Consider Input: Fossils may form in other ways. Fossils can be preserved almost completely. In this process, the organism doesnt change much. As seen below, tree sap may cover an organism. With time, the sap hardens. It turns to into amber. The original organism is preserved. This is very exciting for scientists. They are able to study the DNA of the organism that no longer lives on Earth. Some animals have been found frozen in ice. Others have been found in tar pits after falling in. Molds and casts are another way organisms can be fossilized. Have you ever walked in soft mud and left footprints? Once in a while, these traces of organisms can be preserved. In this case, nothing is left of the organism. A mold is an imprint of an organism that is preserved in rock. The organisms remains break down completely. There is nothing left of the original plant and animal. <sep>What type of fossil is made from when the animal breaks down completely, and only leaves an imprint of the organism?<sep>A Mold


Output: Yes
