input: Please answer the following: I read this background article the other day: Astronomy is very sensitive to light pollution. The night sky viewed from a city bears no resemblance to what can be seen from dark skies.[78] Skyglow (the scattering of light in the atmosphere at night) reduces the contrast between stars and galaxies and the sky itself, making it much harder to see fainter objects. This is one factor that has caused newer telescopes to be built in increasingly remote areas. I am facing a new situation today: Whenever Bill visited Tim's house, they couldn't see that many stars when stargazing . Tim lived in the city. The sky was much clearer at night at Bill's place, because he lived in a rural area. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Where do they see more stars and galaxies, at Tim's or at Bill's?
++++++++++
output: at Bill's
Please answer this: I read this background article the other day: So much rain falling so fast causes some of the damage from a hurricane. But a lot of the damage is caused by storm surge. Storm surge is very high water located in the low pressure eye of the hurricane. The very low pressure of the eye allows the water level to rise above normal sea level. Storm surge can cause flooding when it reaches land ( Figure below ). High winds do a great deal of damage in hurricanes. High winds can also create very big waves. If the large waves are atop a storm surge, the high water can flood the shore. If the storm happens to occur at high tide, the water will rise even higher. I am facing a new situation today: Beach town was hit hard by the hurricane. Hill town was spared, being situated 50 miles south. the eye of the hurricane passed almost through Beach town. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which town had less damage caused by storm surge?
++++++++
Answer: Hill
Problem: I read this background article the other day: Beginning in September 2012, the U.S. Food and Drug Administration will require larger, more prominent cigarette health warnings on all cigarette packaging and advertisements in the United States. These warnings are a significant advancement in communicating the dangers of smoking. These new cigarette health warnings contains nine different warnings that will increase awareness of the specific health risks associated with smoking, such as death, addiction, lung disease, cancer, stroke and heart disease. These warnings include: I am facing a new situation today: David collects cigarette packs of different years. He found that two of his packs, pack A and pack B, are very different. Pack A is from before September 2012, and pack B is from after September 2012. He started searching on the internet to find out why the packs were different. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which pack would induce less awareness of smoking health risks, pack A or pack B?

A: pack A
Problem: Given the question: I read this background article the other day: Rain dissolves fertilizer in the soil. Runoff carries it away. The fertilizer ends up in bodies of water, from ponds to oceans. Nitrogen is a fertilizer in the water. Since there is a lot of nitrogen, it causes algae to grow out of control. Pictured below is a pond covered with algae ( Figure below ). Algae use up carbon dioxide in the water. After the algae die, decomposers break down the dead tissue. The decomposers use up all the oxygen in the water. This creates a dead zone. A dead zone is an area in a body of water where nothing grows because there is too little oxygen. There is a large dead zone in the Gulf of Mexico ( Figure below ). The U.S. states outlined on the map have rivers that drain into the Gulf of Mexico. The rivers drain vast agricultural lands. The water carries fertilizer from these areas into the Gulf. I am facing a new situation today: Two neighboring towns from Texas produced their food in different ways. Silver town was sustainable and didn't use any fertilizers or pesticides, while Gold town did. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which town caused more fertilizer runoff?
++++++++++++++++++++++++++++++++
The answer is:
Gold
input question: I read this background article the other day: A catalyst is a substance that increases the rate of a chemical reaction. A catalyst is a substance that increases the rate of a chemical reaction. The presence of a catalyst is one of several factors that influence the rate of chemical reactions. (Other factors include the temperature, concentration, and surface area of reactants.) A catalyst isn't a reactant in the chemical reaction it speeds up. As a result, it isn't changed or used up in the reaction, so it can go on to catalyze many more reactions. I am facing a new situation today: Henry and Tiffany are performing chemical reactions in their high school chemistry class. Henry performs his reactions with the use of a catalyst. Tiffany performs the same reaction with no catalyst present. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Will Henry's catalyst be used up after it catalyzes some reactions, yes or no????
output answer: no
input question: I read this background article the other day: Earthquakes may take place every day near a volcano. But before an eruption, the number and size of earthquakes increases. This is the result of magma pushing upward into the magma chamber. This motion causes stresses on neighboring rock to build up. Eventually the ground shakes. A continuous string of earthquakes may indicate that a volcano is about to erupt. Scientists use seismographs to record the length and strength of each earthquake. I am facing a new situation today: Two sister villages, both situated near volcanoes, experience daily earthquakes. Green village started recording an increased size and number of earthquakes one day. Blue village didn't experience a change in the number of earthquakes. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which village had more motion causing stresses on neighboring rock????
output answer:
Green
