input question: I read this background article the other day: Greenhouse Effect: The solar energy reaching the surface of the Earth is concentrated in short wavelengths, which can easily penetrate the greenhouse gases, such as carbon dioxide and methane. The Earth, however, is cooler than the sun and it radiates its heat in the form of energy in the far infrared range. These longer wavelengths are partially absorbed by the greenhouse gases and some of the solar heat is returned to Earth. At a certain temperature these processes are in equilibrium and the surface temperature of the Earth is stable. However, if more greenhouse gases are put in the atmosphere the amount of trapped terrestrial radiation increases, leading to an increase in global temperature. I am facing a new situation today: Barb and Dee studied chemistry for a school project. After little debate they decided that Dee will study volatile gases, and Barb will study greenhouse gasses. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which girl studied more about short wavelength solar energy????
output answer: Barb

input question: I read this background article the other day: Figure B above shows an important relationship between the wavelength and frequency of a wave. The top wave clearly has a shorter wavelength than the second wave. However, if you picture yourself at a stationary point watching these waves pass by, more waves of the first kind would pass by in a given amount of time. Thus the frequency of the first waves is greater than that of the second waves. Wavelength and frequency are therefore inversely related. As the wavelength of a wave increases, its frequency decreases. The equation that relates the two is I am facing a new situation today: Robert is generating waves using an oscilloscope in his high school physics class. As part of the experiment, Robert first has to create waves with a long wavelength, waves that we will call long waves. Afterwards, Robert has to create waves with a short wavelength, waves that we will call short waves. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which waves will have a lower frequency????
output answer: long waves

input question: I read this background article the other day: Gibberellins are hormones that cause the plant to grow. When gibberellins are applied to plants by scientists, the stems grow longer. Some gardeners or horticulture scientists add gibberellins to increase the growth of plants. Dwarf plants (small plants), on the other hand, have low levels of gibberellins ( Figure below ). Another function of gibberellins is to stop dormancy (resting time) of seeds and buds. Gibberellins signal that it's time for a seed to germinate (sprout) or for a bud to open. I am facing a new situation today: Two teams of agriculturists used different methods to improve production. Team Corn used organic methods, and team Plum used gibberellins for their crops. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which team use more hormones that cause plants to grow????
output answer: Plum

input question: I read this background article the other day: All of these animal behaviors are important. They help the animals get food for energy, make sure their young survive, or ensure that they, themselves, survive. Behaviors that help animals or their young survive, increase the animals' fitness. Animals with higher fitness have a better chance of passing their genes on to the next generation. If genes control behaviors that increase fitness, the behaviors become more common in the species. This occurs through the process of evolution by natural selection. I am facing a new situation today: Two bears are living in the same forest. One bear, named Teddy, often runs and is active in its daily life. The other bear, Fluffy, is lazy and hardly moves at all. Their levels of fitness are very different with Teddy having a much higher overall fitness level than Fluffy. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Is Fluffy more or less likely than Teddy to pass his genes on to the next generation of bears????
output answer:
less
