Please answer this: Clouds on Earth are made of water vapor. Venus's clouds are a lot less pleasant. They are made of carbon dioxide, sulfur dioxide and large amounts of corrosive sulfuric acid! The atmosphere of Venus is so thick that the pressure on the surface of Venus is very high. In fact, it is 90 times greater than the pressure at Earth's surface! The thick atmosphere causes a strong greenhouse effect. As a result, Venus is the hottest planet. Even though it is farther from the Sun, Venus is much hotter even than Mercury. Temperatures at the surface reach 465C (860F). That's hot enough to melt lead! In year 2200, David is an astronaut and an avid galaxy hopper from a planet hundred light years away. He ended up in the solar system in search of water. He identified three planets, planet A, planet B and planet C. Little did he know that less than a hundred years ago people used to call planet A as Earth, planet B as Venus, and planet C as Mercury. Which planet would have lower pressure on the surface, planet A or planet B?
++++++++
Answer: planet A

Problem: Marine pollution is a generic term for the entry into the ocean of potentially hazardous chemicals or particles. The biggest culprits are rivers and with them many agriculture fertilizer chemicals as well as livestock and human waste. The excess of oxygen-depleting chemicals leads to hypoxia and the creation of a dead zone.Marine debris, which is also known as marine litter, describes human-created waste floating in a body of water. Oceanic debris tends to accumulate at the center of gyres and coastlines, frequently washing aground where it is known as beach litter. Bay city practiced organic farming and used almost no fertilizers. Gulf city practiced conventional farming for it inhabitants, and used vast quantities of fertilizers. Which city caused the entry of less livestock waste into the ocean?

A: Bay

Problem: Given the question: Machines make work easier by increasing the amount of force that is applied, increasing the distance over which the force is applied, or changing the direction in which the force is applied. Contrary to popular belief, machines do not increase the amount of work that is done. They just change how the work is done. So if a machine increases the force applied, it must apply the force over a shorter distance. Similarly, if a machine increases the distance over which the force is applied, it must apply less force. Archimedes was a great scientist. He was also a great inventor of machines. He once said that if he could stand somewhere, he could move the earth with his machine. Hearing that, king of Sicily called Archimedes and his fellow scientist Ptolemy to come up with great inventions. Archimedes, as everyone expected, came up with a great machine. But Ptolemy couldn't do much in such a limited time. So, his device was not a machine. Would Archimedes' device more likely or less likely make work easier than Ptolemy's one?

The answer is:
more likely

input question: Biodiversity is determined by many things, and one of them is abiotic stress. If an environment is highly stressful, biodiversity tends to be low. If abiotic stress does not have a strong presence in an area, the biodiversity will be much higher.This idea leads into the understanding of how abiotic stress and endangered species are related. It has been observed through a variety of environments that as the level of abiotic stress increases, the number of species decreases. This means that species are more likely to become population threatened, endangered, and even extinct, when and where abiotic stress is especially harsh. Italy had two distinct regions. Northern region where the animals are exposed to a lot of abiotic stress, and the southern region, where the animals experience almost no abiotic stress. Which region had more endangered species????
output answer: Northern

Soil is well developed in the forest as suggested by the thick humus layers, rich diversity of large trees and animals that live there. In forests, precipitation exceeds evapotranspiration which results in an excess of water that percolates downward through the soil layers. Slow rates of decomposition leads to large amounts of fulvic acid, greatly enhancing chemical weathering. The downward percolation, in conjunction with chemical weathering leaches magnesium (Mg), iron (Fe), and aluminum (Al) from the soil and transports them downward, a process known as podzolization. This process leads to marked contrasts in the appearance and chemistry of the soil layers. Brad and Frank are two cousins. they both own land in the same county. Frank's parcel is a pine forest, while Brad's is a nice dry grassland with wild flowers and a few shrubs. Which parcel doesn't have a rich diversity of large trees?
----
Answer: Brad's

Q: As a star begins to run low on hydrogen, since the initial quantity has been fused into the denser helium gas, the core will contract due to gravity. The collapsing core increases temperature to the point that the star can begin to fuse helium into carbon. When that happens, the outer portion of the star expands greatly due to the higher temperature. The star can expand to 1000 times the diameter of the sun. At this point, the star is called a red giant . If our sun became a red giant, its surface would expand out past the orbit of Mars. Red giants are red because the surface of the star is cooler than white or blue stars, but remain highly visible because of their gigantic size. John is an amateur astronomer. He recently found two stars, star A and star B. Upon observation, he figured out that star A is a blue star, but star B is a red giant. He had to do some research to find out the differences between them. Would star A have greater or smaller diameter than star B?
A:
smaller
