input: Please answer the following: I have a new situation: Two students were learning about atmospheres and planets. Dan learned about the atmosphere of Earth, while Nate learned about planet Venus and its atmosphere. But I can use this background: 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! What is an answer for this question: Which student learned less about the planet with the greater atmosphere?

input: Please answer the following: I have a new situation: Mike is studying chemistry for his exam. Today, he is studying the properties of acids. He picks up an acid solution that he labels as solution A. To compare it with another solution he chooses a solution that is not an acid. He labels it as solution B. But I can use this background: If a solution has a higher concentration of hydronium ions than pure water, it has a pH lower than 7. A solution with a pH lower than 7 is called an acid . As the hydronium ion concentration increases, the pH value decreases. Therefore, the more acidic a solution is, the lower its pH value is. Did you ever taste vinegar? Like other acids, it tastes sour. Stronger acids can be harmful to organisms. For example, stomach acid would eat through the stomach if it were not lined with a layer of mucus. Strong acids can also damage materials, even hard materials such as glass. What is an answer for this question: Would solution B have higher or lower pH value than solution A?
++++++++++
output: higher

input: Please answer the following: I have a new situation: Los Angeles receives a steady year-long supply of high amounts of sunlight and wind. Because of this, Los Angeles is able to power many of its buildings and factories using renewable resources. Las Vegas, however, receives barely any sunlight or wind throughout the entire year. As a result, they use little renewable resources and instead power most of the city through non-renewable resources like fossil fuels. But I can use this background: Natural resources include energy, minerals and other materials. Natural resources may be renewable or non-renewable. Non-renewable resources cannot be replaced. When they're gone, they're gone. Renewable resources can be replaced. They can supply human activities forever. Fossil fuels are crucial for modern human society. Fossil fuels are essential for transportation, industry and agriculture. Renewable energy resources tend to be clean. They emit fewer pollutants and greenhouse gases than fossil fuels. Renewable resources often have other problems. They are more costly and less efficient than fossil fuels. Still, they have many advantages. Research is going into developing renewable resources. Conservation is the best way to increase resource availability. Anyone can conserve! You and your family can. Society can. The world can. Just reduce, reuse, recycle. What is an answer for this question: Which city, Los Angeles or Las Vegas, emits less pollutants?
++++++++++
output: Los Angeles

input: Please answer the following: I have a new situation: Toronto is home to one of the leading manufacturers of aerosol sprays in the country. Because of this, homes in Toronto often spray high levels of aerosol on a regular basis. In Saskatchewan, meanwhile, the local government enacted a ban on aerosol sprays several years ago, so their level of aerosol use is now essentially zero. But I can use this background: Unfortunately, the layer of good ozone is being destroyed by air pollution. The chief culprits are chlorine and bromine gases. They are released in aerosol sprays, coolants, and other products. Loss of ozone has created an ozone hole over Antarctica. Ozone depletion results in higher levels of UV radiation reaching Earth. In humans, this increases skin cancers and eye cataracts. It also disturbs the nitrogen cycle, kills plankton, and disrupts ocean food webs. The total loss of the ozone layer would be devastating to most life. Its rate of loss has slowed with restrictions on pollutants, but it is still at risk. What is an answer for this question: Which city, Toronto or Saskatchewan, will be contributing more to skin cancer risk?

Toronto
