Problem: Given the question: A vapor light produces visible light by electroluminescence. The bulb contains a small amount of solid sodium or mercury as well as a mixture of neon and argon gases. When an electric current passes through the gases, it causes the solid sodium or mercury to change to a gas and emit visible light. Sodium vapor lights, like these streetlights, produce yellowish light. Mercury vapor lights produce bluish light. Vapor lights are very bright and energy efficient. The bulbs are also long lasting. James is driving down the street in his town. For some reason today hes very curious about the things that he sees. He looks around as hes driving and the street lights catch his attention. He realizes that he's never seen someone changing the bulbs in a street light. He also wonders if its a film on the light that makes them have that color or something inside. Given James sees the yellow street light light up, which type of vapor light is it likely to be, Mercury or Sodium?

The answer is:
Sodium

input question: 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. Ben and Mike both studied earthquakes, while Mike was more interested specifically in mantle melting and related phenomena. Which person studied less about volcanoes at convergent plate boundaries????
output answer: Ben

Scientists think that the earliest flowers attracted insects and other animals, which spread pollen from flower to flower. This greatly increased the efficiency of fertilization over wind-spread pollen, which might or might not actually land on another flower. To take better advantage of this "animal labor," plants evolved traits such as brightly colored petals to attract pollinators. In exchange for pollination, flowers gave the pollinators nectar. Scientists studied two groups of plants. Group F had plants with flowers, group W had plants that fertilize over wind- spread pollen. Flowering plants were more efficient. Which group of plants has a higher fertilization efficiency?
----
Answer: Group F

Q: While people have been able to prevent certain viral diseases by vaccinations for many hundreds of years, the development of antiviral drugs to treat viral diseases is a relatively recent development. Antiviral drugs are medications used specifically for treating the symptoms of viral infections. The first antiviral drug was interferon , a substance that is naturally produced by certain immune cells when an infection is detected. Over the past twenty years the development of antiretroviral drugs (also known as antiretroviral therapy, or ART) has increased rapidly. This has been driven by the AIDS epidemic. Two brothers went on vacation. Tom partied heavily, and found out that he was infected with the HIV virus. Tim was more moderate, he went to the beach to get a sun tan, but he got an infection as well. Tim found out he got a bacterial infection and had to take antibiotics. Which brother didn't have to consider antiretroviral therapy?
A: Tim

Question: Protozoa generally feed by engulfing and digesting other organisms. As consumers, they have various roles in food chains and webs. Some are predators. They prey upon other single-celled organisms, such as bacteria. In fact, protozoa predators keep many bacterial populations in check. Other protozoa are herbivores. They graze on algae. Still others are decomposers. They consume dead organic matter. There are also parasitic protozoa that live in or on living hosts. For example, the protozoan that causes malaria lives inside a human host. For their part, protozoa are important food sources for many larger organisms, including insects and worms. Reed started studying protozoa and was more interested in the predatorial behaviors of protozoa, while Brad wanted to know more about other types of protozoa, suck as grazers and decomposers. Which person learned less about protozoa preying upon bacteria?
Answer: Brad

Please answer this: Animals and some bacteria and fungi carry out lactic acid fermentation. Lactic acid is a waste product of this process. Our muscles perform lactic acid fermentation during strenuous exercise, since oxygen cannot be delivered to the muscles quickly enough. The buildup of lactic acid is believed to make your muscles sore after exercise. Bacteria that produce lactic acid are used to make cheese and yogurt. The lactic acid causes the proteins in milk to thicken. Lactic acid also causes tooth decay, because bacteria use the sugars in your mouth for energy. Two groups of microbiology students studied about the fermentation process. Group A studied about alcoholic and acetic fermentation, while group B studied about lactic fermentation. Which group learned less about the human muscles?
++++++++
Answer:
Group A
