Problem: Given the question: Please answer correctly the following question related to the paragraph below. Which river didn't have a food source mostly derived from the trees? Two rivers spring from the same mountain. Olt was a fast moving river, while Mures river was slow moving and deep. Both rivers are very important for the local economies. Hint: The major zones in river ecosystems are determined by the river bed's gradient or by the velocity of the current. Faster moving turbulent water typically contains greater concentrations of dissolved oxygen, which supports greater biodiversity than the slow moving water of pools. These distinctions form the basis for the division of rivers into upland and lowland rivers. The food base of streams within riparian forests is mostly derived from the trees, but wider streams and those that lack a canopy derive the majority of their food base from algae. Anadromous fish are also an important source of nutrients. Environmental threats to rivers include loss of water, dams, chemical pollution and introduced species. A dam produces negative effects that continue down the watershed. The most important negative effects are the reduction of spring flooding, which damages wetlands, and the retention of sediment, which leads to loss of deltaic wetlands.

The answer is:
Mures
input question: Please answer correctly the following question related to the paragraph below. Which country would see less rodents in agricultural lands, France or Germany? Large birds are natural predators of rodents. Unfortunately, rodents consume crops in farmlands. In recent years, use of chemicals in agriculture has seen reduced number of large birds in Germany. But in some places in France farmers are cautions about using chemicals in agriculture. As a result, large bird population had been stable in France. Hint: Predators play an important role in an ecosystem. For example, if they did not exist, then a single species could become dominant over others. Grazers on a grassland keep grass from growing out of control. Predators can be keystone species . These are species that can have a large effect on the balance of organisms in an ecosystem. For example, if all of the wolves are removed from a population, then the population of deer or rabbits may increase. If there are too many deer, then they may decrease the amount of plants or grasses in the ecosystem. Decreased levels of producers may then have a detrimental effect on the whole ecosystem. In this example, the wolves would be a keystone species.???
output answer: France
Please answer correctly the following question related to the paragraph below. Which rock emits more radiation? There are two rocks that scientists are looking at. Rock A is located near the lava stored in an active volcano, and rock B is outside this volcano near the base of it. The scientists are currently trying to find a way to safely transport both rocks back to a lab so they can get these rocks under a microscope to look at them. However, they are currently struggling to figure out an effective way to lift rock A out of the volcano. Hint: Emission is the opposite of absorption, it is when an object emits radiation. Objects tend to emit amounts and wavelengths of radiation depending on their "black body" emission curves, therefore hotter objects tend to emit more radiation, with shorter wavelengths. Colder objects emit less radiation, with longer wavelengths. For example, the Sun is approximately 6,000 K (5,730 C; 10,340 F), its radiation peaks near 500 nm, and is visible to the human eye. Earth is approximately 290 K (17 C; 62 F), so its radiation peaks near 10,000 nm, and is much too long to be visible to humans. The light that is observed on photographs of earth from space and with the naked eye is only reflected visible light.

Answer: Rock A
Q: Please answer correctly the following question related to the paragraph below. Which girl studied less about short wavelength solar energy? 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. Hint: 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.
A: Dee
Question: Please answer correctly the following question related to the paragraph below. In which case more of the longer wavelengths would be absorbed in the atmosphere, case A or case B? John was interested in climate change issues. To that end, he studied two imaginary situations, case A and case B. In case A, there would not be excessive greenhouse gases in the atmosphere. On the contrary, in case B, the amount of greenhouse gases in the atmosphere would increase dramatically. John realized that the amount of greenhouse gases in the atmosphere has many practical implications.

Answer: case B
Please answer this: Please answer correctly the following question related to the paragraph below. Which fruit lasted longer, apples or peaches? Helen got lots of different fruit as a gift from a friend that owned an orchard. She received apples, pears, apricots, peaches, plums, quince, among others. She decided to candy apples, apricots, and pears, and to keep the others fresh for as long as possible. Hint: 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]

apples
