Please answer this: I can use this background: When wind waves approach to coast area from deep water, the waves change their heights and lengths. The wave height becomes higher and the wavelength becomes shorter as the wave velocity is slowed when ocean waves approach to the shore. If the water depth is sufficiently shallow, the wave crest become steeper and the trough gets broader and shallower; finally, the ocean waves break at the shore. The motions of wave breaking are different with along to the steepness of shores and waves, and can be categorized by below three types.[11][12] Now, I have a new situation: The tourist village had two beaches: Coral beach with nice sand and deeper water was preferred by families, and Surfer beach which had shallow water was a surfer's heaven. Answer this question please: Which beach had waves with a steeper wave crest?
++++++++
Answer: Surfer beach
Problem: I can use this background: Mantle melting can come about three ways: (1) when the temperature rises, (2) if the pressure lowers (which lowers the melting point), and (3) if water is added, which lowers the melting point. Two of these (1 and 3) might explain why there are volcanoes at convergent plate boundaries: the temperature of the subducting plate increases as it sinks into the hot mantle (1). Sediments lying on top of the subducting plate contain water. As the sediments subduct, the water rises into the overlying mantle material. This lowers the melting temperature of the mantle (3). When the mantle above the subducting plate melts, volcanoes form above it. This leads to volcanoes in an island arc or continental arc. Now, I have a new situation: Two researches studied the Earth's mantle. Clint studied mantle melting, and his pal Uri decided to study other mantle related phenomena. Answer this question please: Which researcher read more about adding water to the mantle?

A: Clint
Problem: Given the question: I can use this 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. Now, I have a new 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 this question please: Which patient's alveolus would have normal concentrations of oxygen and carbon dioxide, patient A or patient B?
++++++++++++++++++++++++++++++++
The answer is:
patient B
input question: I can use this background: Candied fruit, also known as crystallized fruit or glace fruit, has existed since the 14th century. Whole fruit, smaller pieces of fruit, or pieces of peel, are placed in heated sugar syrup, which absorbs the moisture from within the fruit and eventually preserves it. Depending on size and type of fruit, this process of preservation can take from several days to several months.[1] This process allows the fruit to retain its quality for a year.[2] The continual process of drenching the fruit in syrup causes the fruit to become saturated with sugar, preventing the growth of spoilage microorganisms due to the unfavourable osmotic pressure this creates.[3] Now, I have a new situation: Dan harvested lots of fruit and decided to candy some of them to preserve them. He left some fruit fresh for the family to enjoy. He candied apples, pears, plums, and quince. He didn't candy oranges, blueberries, apricots and peaches. Answer this question please: Which fruit retained their quality longer, pears or blueberries????
output answer: pears
I can use this background: During the Cold War, the Arctic became a place where the United States, Canada, and the Soviet Union performed significant research that has been essential to the study of climate change in recent years. A major reason why research in the Arctic is essential for the study of climate change is because the effects of climate change will be felt more quickly and more drastically in higher latitudes of the world as above average temperatures are predicted for Northwest Canada and Alaska. From an anthropological point of view, researchers study the native Inuit peoples of Alaska as they have become extremely accustomed to adapting to ecological and climate variability.[1] Now, I have a new situation: Two sister cities, located at different altitude, are affected differently by climate change. Bergen is at 60 degrees N, while Seattle is at 47 degrees N latitude. Answer this question please: Which city became less accustomed to adapting to climate variability?
----
Answer: Seattle
Q: I can use this background: Reptiles are a class of animals comprising turtles, tuataras, lizards, snakes and crocodiles. They are tetrapods, but the snakes and a few species of lizard either have no limbs or their limbs are much reduced in size. Their bones are better ossified and their skeletons stronger than those of amphibians. The teeth are conical and mostly uniform in size. The surface cells of the epidermis are modified into horny scales which create a waterproof layer. Reptiles are unable to use their skin for respiration as do amphibians and have a more efficient respiratory system drawing air into their lungs by expanding their chest walls. The heart resembles that of the amphibian but there is a septum which more completely separates the oxygenated and deoxygenated bloodstreams. The reproductive system has evolved for internal fertilization, with a copulatory organ present in most species. The eggs are surrounded by amniotic membranes which prevents them from drying out and are laid on land, or develop internally in some species. The bladder is small as nitrogenous waste is excreted as uric acid.Turtles are notable for their protective shells. They have an inflexible trunk encased in a horny carapace above and a plastron below. These are formed from bony plates embedded in the dermis which are overlain by horny ones and are partially fused with the ribs and spine. The neck is long and flexible and the head and the legs can be drawn back inside the shell. Turtles are vegetarians and the typical reptile teeth have been replaced by sharp, horny plates. In aquatic species, the front legs are modified into flippers.Tuataras superficially resemble lizards but the lineages diverged in the Triassic period. There is one living species, Sphenodon punctatus. The skull has two openings (fenestrae) on either side and the jaw is rigidly attached to the skull. There is one row of teeth in the lower jaw and this fits between the two rows in the upper jaw when the animal chews. The teeth are merely projections of bony material from the jaw... Now, I have a new situation: Two animal collectors met online to talk about trading animals. Greg was a reptile collector and owned most reptile species. Danny collected rare birds but was thinking about buying some reptiles. Answer this question please: Which person owned no lizards?
A:
Danny
