Input: Consider Input: Relying on an animal to come by is risky. A flower may have to wait a long time for the right animals to come by. What if one never passes close enough to the flower? Hoping the wind will blow is also risky for a plant. What if the wind does not blow? What if the blowing pollen does not land on another flower? The wind could even blow the pollen over the ocean where it is wasted. Giving free nectar is costly. It is not a good use of the plants energy. A plant uses a lot of energy to produce nectar. Some animals may just drink the nectar. They may not carry off any pollen in return. To improve their chances, plants evolved special traits. For example, they developed ways to hide their nectar. Only certain animals were able to get at the plants hidden nectar. These specific animals might be more likely to visit only flowers of the same species. This was also a benefit for some animals. Animals also evolved special traits to get to the nectar. <sep>What do some plants provide that entices animals to visit them?<sep>Photosynthesis

Output: No


Input: Consider Input: Dr. Benjamin Stone is a hotshot young surgeon who longs to leave the drudgery of a Washington , D.C. emergency room and finally leaps at his chance at more money and less death as a plastic surgeon in Beverly Hills .  On his last day , Ben's relationship with his co-workers is presumed to be anything but a warm one .  None of his colleagues will join him for a drink and a cake in his honor has an iced portion of the phrase `` Good riddance , asshole '' sliced out .  Ben's cross-country drive in a 1956 Porsche 356 Speedster is interrupted when he crashes in the rural hamlet of Grady , South Carolina .  The crash damages the fence of local Judge Evans , who sentences him to community service at a nearby hospital .  Ben offers to pay for the fence , but the stern judge increases his community service each time he talks back .  Defeated , he reports to the hospital , where Nurse Packer humbles him by ordering him to clock in and out , as would a factory worker .  Though upset , Ben quickly makes friends with Mayor Nick Nicholson , the town cafe's proprietor/head waitress , and Melvin , the local mechanic tasked with repairing Ben's car .  Ben soon finds his clinic work to be much more laid-back than the emergency room .  He has simple cases such as spots before the eyes , fishing hook impalings , and even reading mail for a young illiterate couple , whose baby he later delivers .  The experience also humbles Ben when he mistreats a case of mitral valve regurgitation leading to late cyanosis in the child . <sep>Where did Judge Evans live?<sep>Grady,  South Carolina

Output: Yes


Input: Consider Input: An atom is the very smallest particle that still the elements properties. All the atoms of an element are alike. They are also different from the atoms of all other elements. For example, atoms of gold are always the same. It does not matter if they are found in a gold nugget or a gold ring. All gold atoms have the same structure and properties. For example, all gold atoms contain 79 protons. One of golds unique properties is that it is a great conductor of electricity. Gold is a better conductor of electricity than copper. Gold is more rare and expensive than copper. Copper is used in house wiring. Gold is far too expensive. <sep>How is gold different from copper?<sep>Gold is more expensive and rarer than copper


Output: Yes
