Q: Given the background: Turner et al (2006) derived crash prediction models for this report's predecessor and found a pronounced 'safety in numbers' effect in the models. Using the crash prediction model for mid-block locations, generic motorist and cyclist volumes can be used to demonstrate the impacts on the expected crash rate of varying motor vehicle and cycle volumes. As shown in figure 2.20, an increase in the proportion of cyclists to the overall traffic volume causes an increase in expected crashes at mid-block locations, but the crash rate increases at a decreasing rate. That is to say, the crash rate per cyclist goes down as the cycle volume increases. and the situation: Berg village and Hill village are renowned for the high number of cyclists living there. Berg village dealt with many traffic casualties because of narrower streets and lanes, While Hill village had wide streets, more traffic signals and a greater number of cyclists. Answer the following question: Which village had a smaller number of cyclists?
A: Berg

Question: Given the background: The brains of all mammals have a unique layer of nerve cells covering the cerebrum. This layer is called the neocortex (the pink region of the brains in Figure above ). The neocortex plays an important role in many complex brain functions. In some mammals, such as rats, the neocortex is relatively smooth. In other mammals, especially humans, the neocortex has many folds. The folds increase the surface area of the neocortex. The larger this area is, the greater the mental abilities of an animal. and the situation: Two students read about brains in the animal kingdom. Tom read more about the brains of mammals, while Reed learned more about the brains of amphibians. Answer the following question: Which student learned less about the neocortex?
Answer: Reed

[Q]: Given the background: 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. and the situation: Two neighboring towns had different demographics. Hill town had younger inhabitants, most of them in their 30's and 40's. Lake town was inhabited by elderly people, most of them above 65 years of age. Answer the following question: Which town had more people that have retired from work?
****
[A]: Lake

input: Please answer the following: Given the background: As a star begins to run low on hydrogen, since the initial quantity has been fused into the denser helium gas, the core will contract due to gravity. The collapsing core increases temperature to the point that the star can begin to fuse helium into carbon. When that happens, the outer portion of the star expands greatly due to the higher temperature. The star can expand to 1000 times the diameter of the sun. At this point, the star is called a red giant . If our sun became a red giant, its surface would expand out past the orbit of Mars. Red giants are red because the surface of the star is cooler than white or blue stars, but remain highly visible because of their gigantic size. and the situation: A star names Andromeda has been being observed for years. Over time, it has been seen that the star remains visible but has been turning more and more red. Answer the following question: Which type of star is Andromeda becoming, a Red Giant, or a white star?
++++++++++
output: Red Giant

Please answer this: Given the background: The Fink effect, also known as "diffusion anoxia",[1] "diffusion hypoxia",[2] or the "third gas effect",[3] is a factor that influences the pO2 (partial pressure of oxygen) within the alveolus. When water-insoluble gases such as anesthetic agent N2O (nitrous oxide) are breathed in large quantities they can be dissolved in body fluids rapidly. This leads to a temporary increase in both the concentrations and partial pressures of oxygen and carbon dioxide in the alveolus. and the situation: An accident occurred in a local chemical factory. Consequently, large amount of various gases been released to the atmosphere. Local hospital is evaluating all the patients who have been affected by this accident. John, a doctor at the hospital, is seeing two patients, patient A and patient B. He concluded that patient A was having Fink effect. But he didn't see any sign of Fink effect in patient B. Answer the following question: Which patient would have increased partial pressure of oxygen in the alveolus?
++++++++
Answer: patient A

Question: Given the background: Collision theory tells us that molecules need to collide in order for a reaction to take place. All else being equal, anything that increases the frequency of collisions would also increase the rate of reaction. One way to do this is to increase the concentrations of one or more of the reactants. Using a real world example, a busy freeway will experience much more frequent car collisions than a fairly empty neighborhood street. Similarly, forcing more randomly moving molecules into the same amount of space will cause an increased number of collisions over a given length of time, providing the reactants with more opportunities to transform into products. and the situation: Jordan and Elizabeth are performing a chemistry experiment for the science fair. Jordan uses a high concentration of the reactants when starting his reactions. Elizabeth uses a low concentration of the reactants when she starts her reactions. Answer the following question: Who will have reactions that occur at a higher rate?
Answer:
Jordan
