input question: I read this background article the other day: A vapor light also 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 the streetlight pictured in the Figure below , produce yellowish light. Mercury vapor lights produce bluish light. In addition to lighting city streets, vapor lights are used to light highways and stadiums. The bulbs are very bright and long lasting so they are a good choice for these places. I am facing a new situation today: Joey just purchased two new vapor light bulbs for his apartment and is excited to install them since they glow neat colors. He is going to install a different bulb in each room to give different colored glows to the rooms and to make his apartment seem more dynamic. In his bedroom he has decided to install a bulb that gives off a blue glow. He also picked up a bulb that glows yellow and will be putting that in his closet. However, after screwing the bulbs in, only the one in his closet glows, and Joey is not sure why. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: The bulb in which room does have an electric current????
output answer: closet

input question: I read this background article the other day: Type 2 diabetes is much more common than type 1 diabetes. Type 2 diabetes occurs when body cells no longer respond normally to insulin. The pancreas still makes insulin, but the cells of the body can't use it. Being overweight and having high blood pressure increase the chances of developing type 2 diabetes. This type of diabetes usually develops in adulthood. However, it is becoming more common in teens and children because more young people are overweight now than ever before. I am facing a new situation today: The Jones family and the Bell family both entered a medical study for diabetes.The members of Jones family had mostly type 1 diabetes, while Bell family members had type 2 diabetes because they ate junk-food. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which family had fewer members that were overweight????
output answer: Jones

input question: I read this background article the other day: Arbuscular mycorrhizal fungi vary across many environmental gradients. Their tolerance to freezing and drying is known to shift between AM fungal taxa. AM fungi become less prevalent and diverse at higher soil nutrient and moisture concentrations, presumably because both plants allocate less carbon to AM fungi and AM fungi reallocate their resources to intraradical hyphae in these environmental conditions. Over the long term, these environmental conditions can even create local adaptation between plant hosts, AM fungi and the local soil nutrient concentrations. I am facing a new situation today: Greg and Paul were two neighbors. They were both into mycology. Greg researched AM fungi, while Paul studied other types of mycorrhizal fungi. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which researcher learned more about plants allocating less carbon to AM fungi????
output answer: Greg

input question: I read this background article the other day: Gamma rays, X-rays and the higher energy range of ultraviolet light constitute the ionizing part of the electromagnetic spectrum. The word "ionize" refers to the breaking of one or more electrons away from an atom, an action that requires the relatively high energies that these electromagnetic waves supply. Further down the spectrum, the non-ionizing lower energies of the lower ultraviolet spectrum cannot ionize atoms, but can disrupt the inter-atomic bonds which form molecules, thereby breaking down molecules rather than atoms; a good example of this is sunburn caused by long-wavelength solar ultraviolet. The waves of longer wavelength than UV in visible light, infrared and microwave frequencies cannot break bonds but can cause vibrations in the bonds which are sensed as heat. Radio wavelengths and below generally are not regarded as harmful to biological systems. These are not sharp delineations of the energies; there is some overlap in the effects of specific frequencies.The word radiation arises from the phenomenon of waves radiating (i.e., traveling outward in all directions) from a source. This aspect leads to a system of measurements and physical units that are applicable to all types of radiation. Because such radiation expands as it passes through space, and as its energy is conserved (in vacuum), the intensity of all types of radiation from a point source follows an inverse-square law in relation to the distance from its source. Like any ideal law, the inverse-square law approximates a measured radiation intensity to the extent that the source approximates a geometric point. I am facing a new situation today: A scientists has discovered two new types of radiation. He notes that radiation type A has the ability to break away atoms from molecules, while radiation type B simply causes them to vibrate. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which radiation causes ionization, radiation type A or B????
output answer:
A
