Problem: Given the question: 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. Given the paragraph above, please answer correctly the following question: Who would most likely make decisions at least as good a known or expected outcome, John or Keith? Hint: 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).

input question: Joe studied the lives of humans. He studied 2 groups of people. Group G had people over 65 in it, and group Y had people under 65 years old in it. Given the paragraph above, please answer correctly the following question: Which group had more people that have free time for hobbies? Hint: Old age begins in the mid-60s and lasts until the end of life. Most people over 65 have retired from work, freeing up their time for hobbies, grandchildren, and other interests. Stamina, strength, reflex time, and the senses all decline during old age, and the number of brain cells decreases as well. The immune system becomes less efficient, increasing the risk of serious illnesses such as cancer and pneumonia. Diseases such as Alzheimer's disease that cause loss of mental function also become more common.???
output answer: Group G
Bobby and Will were two friends attending a genetics course. Bobby studied a small, isolated group of mammals. Will studied a large, healthy population of the same species. Given the paragraph above, please answer correctly the following question: Which person observed a 'genetic bottleneck'? Hint: Declines in population size can result in a loss of genetic diversity, and owing to genetic variation's role in the evolutionary potential of a species, this could in turn result in an observable Allee effect. As a species' population becomes smaller, its gene pool will be reduced in size as well. One possible outcome from this genetic bottleneck is a reduction in fitness of the species through the process of genetic drift, as well as inbreeding depression. This overall fitness decrease of a species is caused by an accumulation of deleterious mutations throughout the population. Genetic variation within a species could range from beneficial to detrimental. Nevertheless, in a smaller sized gene pool, there is a higher chance of a stochastic event in which deleterious alleles become fixed (genetic drift). While evolutionary theory states that expressed deleterious alleles should be purged through natural selection, purging would be most efficient only at eliminating alleles that are highly detrimental or harmful. Mildly deleterious alleles such as those that act later in life would be less likely to be removed by natural selection, and conversely, newly acquired beneficial mutations are more likely to be lost by random chance in smaller genetic pools than larger ones.Although the long-term population persistence of several species with low genetic variation has recently prompted debate on the generality of inbreeding depression, there are various empirical evidences for genetic Allee effects. One such case was observed in the endangered Florida panther (Puma concolor coryi). The Florida panther experienced a genetic bottleneck in the early 1990s where the population was reduced to 25 adult individuals. This reduction in genetic diversity was correlated with defects that include lower sperm quality, abnormal testosterone levels, cowlicks, and kinked tails. In response, a genetic rescue plan was put in motion and several female pumas from Texas were introduced into the Florida population. This action quickly led...

Q: Two ancient continents both had a great bird population. At some point in time, the continent of MU experienced a great drought that lasted for several years. The other continent, Lemuria, was unaffected by the drought. Given the paragraph above, please answer correctly the following question: Which continent had more small-beaked birds die in the drought? Hint: A period of very low rainfall occurred while the Grants were on the islands. The drought resulted in fewer seeds for the finches to eat. Birds with smaller beaks could eat only the smaller seeds. Birds with bigger beaks were better off. They could eat seeds of all sizes. Therefore, there was more food available to them. Many of the small-beaked birds died in the drought. More of the big-beaked birds survived and reproduced. Within just a couple of years, the average beak size in the finches increased. This was clearly evolution by natural selection.
A: MU
Question: Scientists are observing two of the same gases at different temperatures. They are observing the speed of the particles in the gases to see how fast they are moving. Gas A has particles moving very quickly, but Gas B has particles that are hardly moving at all. Given the paragraph above, please answer correctly the following question: Which gas is at a lower temperature? Hint: We discussed earlier some basic principles about the behavior of gases called the kinetic-molecular theory. Among other things, this theory suggests that gas molecules are in constant motion, and the average speed of the individual gas particles is dependent upon temperature the higher the temperature, the faster the molecules move. It is not just gas particles that are in constant motion. The molecules and ions that make up liquids and solutions are also continually moving in nearly random directions. As a result, molecules and ions in a solution will collide with one another fairly frequently. As with gases, a temperature increase will produce an increase in the average particle speed.
Answer: Gas B
Please answer this: Two teams of researchers studied different diseases. team Alpha studied people with cholesterol, while team Beta studied people with Parkinson's disease. Given the paragraph above, please answer correctly the following question: Which team studied fewer people with cholesterol and other materials deposited on the interior of the arterial wall? Hint: Cholesterol has been implicated in heart disease for decades. Atherosclerosis is a disorder of the arteries in which cholesterol and other materials are deposited on the interior of the arterial wall. These deposits lead to the formation of plaques that can restrict or even block the flow of blood through these blood vessels (see Figure below ). A decrease in the flow of blood can lead to high blood pressure and a lowered oxygen supply to the heart muscle. A complete blockage of blood flow to parts of the heart (a heart attack) can cause significant damage due to oxygen deprivation, in some cases leading to death.
