Please answer this: In the U.S., the majority of electricity is produced by burning coal or other fossil fuels. This causes air pollution, acid rain, and global warming. Fossil fuels are also limited and may eventually run out. Like fossil fuels, radioactive elements are limited. In fact, they are relatively rare, so they could run out sooner rather than later. On the other hand, nuclear fission does not release air pollution or cause the other environmental problems associated with burning fossil fuels. This is the major advantage of using nuclear fission as a source of energy. Park city used fossil fuels to produce their electricity. They were less conscious about the environment than their neighbors from Lake city. People from Lake city used nuclear fission as an energy source. Which city used fewer radioactive elements for their energy needs?
++++++++
Answer: Park

Please answer this: Blood vessels help regulate body processes by either constricting (becoming narrower) or dilating (becoming wider). These actions occur in response to signals from the autonomic nervous system or the endocrine system. Constriction occurs when the muscular walls of blood vessels contract. This reduces the amount of blood that can flow through the vessels (see Figure below ). Dilation occurs when the walls relax. This increases blood flows through the vessels. Greg is a physician working for the city hospital. Today he is seeing two patients, patient A and patient B. He noticed that patient A's blood vessels are constricted, but blood vessels of patient B are dilated. He needs to prescribe medicine according to his observation. Which patient would have less blood passing through the vessels, patient A or patient B?
++++++++
Answer: patient A

Please answer this: An optimal decision is a decision that leads to at least as good a known or expected outcome as all other available decision options. It is an important concept in decision theory. In order to compare the different decision outcomes, one commonly assigns a utility value to each of them. If there is uncertainty as to what the outcome will be, then under the von NeumannMorgenstern axioms the optimal decision maximizes the expected utility (a probabilityweighted average of utility over all possible outcomes of a decision). John and Keith are playing a decision making game. They have three decisions to make decision A, decision B, and decision C. Decision A and decision B have certain outcome, but decision C's outcome is uncertain. John would apply optimal decision making process while Keith would rather rely on his hunches. Will John most likely make or fail to make at least as good a known or expected outcome?
++++++++
Answer:
most likely make
