Please answer this: I can use this background: Mass is a measure of the amount of matter in a substance or an object. The basic SI unit for mass is the kilogram (kg), but smaller masses may be measured in grams (g). To measure mass, you would use a balance. In the lab, mass may be measured with a triple beam balance or an electronic balance, but the old-fashioned balance pictured below may give you a better idea of what mass is. If both sides of this balance were at the same level, it would mean that the fruit in the left pan has the same mass as the iron object in the right pan. In that case, the fruit would have a mass of 1 kg, the same as the iron. As you can see, however, the fruit is at a higher level than the iron. This means that the fruit has less mass than the iron, that is, the fruit's mass is less than 1 kg.  Now, I have a new situation: Johnathan is trying to find two blocks of wood with the same mass for a project he is working on. He doesn't have a balance, so he makes a crude one out of materials he has on hand. He put a block of wood on either side and the block on the left side was at a lower level than the block on the right.                                                                       Sarah is using a traditional balance to estimate the mass of her peppers. She wants to make 1 kg bushels to sell at the farmers market so she puts a 1 kg weight on the right side and the peppers on the left side.  Answer this question please: If the 1 kg weight is higher than the peppers does Sarah need to add more peppers or remove peppers?

Answer: remove peppers


Problem: I can use this background: Current Situation : Currently the heating effect of extra greenhouse gases (since the start of the industrial revolution) is equal to about . Thus the recent period has recorded parallel increases in concentration of carbon dioxide and average global temperature. As more greenhouse gases are put into the atmosphere the temperature will increase further. There are certain effects of a warmer Earth (discussed more in optional section), which could accelerate the process, even if no more greenhouse gases are put into the atmosphere (an unlikely prospect for the foreseeable future).  Now, I have a new situation: A group of researches studied the green house gas emissions and their effects on Earth and people during the eighties compared to the twenties.  Answer this question please: During which decade did Earth experience a more prevalent heating effect because of green house gas emissions?

A: eighties


Problem: Given the question: I can use this background: The frequency of sound waves is measured in hertz (Hz), or the number of waves that pass a fixed point in a second. Human beings can normally hear sounds with a frequency between about 20 Hz and 20,000 Hz. Sounds with frequencies below 20 hertz are called infrasound . Sounds with frequencies above 20,000 hertz are called ultrasound . Some other animals can hear sounds in the ultrasound range. For example, dogs can hear sounds with frequencies as high as 50,000 Hz. You may have seen special whistles that dogs but not people can hear. The whistles produce a sound with a frequency too high for the human ear to detect. Other animals can hear even higher-frequency sounds. Bats, for example, can hear sounds with frequencies higher than 100,000 Hz.  Now, I have a new situation: David wants to categorize animals according to the sound waves they can hear. Eventually, he was able to categorize them in three different groups, group A, group B, and group C. He placed the animals that can only hear ifrasound in group A. Then he placed the animals that are only able to hear the same frequency of sound waves as humans do in group B. The last group of animals were able to hear only ultrasound. He placed them in group C.  Answer this question please: Which group would be able to hear the highest frequency, group A, group B, or group C?
++++++++++++++++++++++++++++++++
The answer is:
group C


input question: I can use this background: One of the most adverse impacts of poor waste management, especially municipal waste, is the incidence and prevalence of diseases such as malaria and respiratory problems, as well as other illnesses through the contamination of ground water. Biomedical wastes pose great danger in Bangladesh too as a report estimated that 20% of the biomedical waste is "highly infectious" and is a hazard since it is often disposed of into the sewage system or drains.[6]  Such poor sanitation has serious consequences for the health of the residents and a report suggests that "most of the child mortality could be related with this problem".[7]  With regards to the living standards, solid waste leads to blockage in the drainage system which leads to flooding in the streets. Consequently, mosquitoes and bad odour are among the negative impacts resulted.[7]  Now, I have a new situation: The hospital in Y city had a good disposal site in which they disposed of Biomedical wastes, but the hospital in the neighboring city X had big problems, because the biomedical waste contaminated the ground water and affected the population.  Answer this question please: Which city had a lower incidence of respiratory problems????
output answer: Y city


I can use this background: Many people enjoy riding in hot air balloons. Some use them for romantic picnics and marriage proposals. Others race in competitions. Being above the earth gives a whole new perspective on the world around us. As the beginning of a hot air balloon ride, the balloon is flat because the pressure inside the balloon equals the pressure outside. When the air inside the balloon is heated, the speed of movement of those air molecules increases and the pressure goes up. After a while the balloon is completely expanded and the flight is ready to take off.  Now, I have a new situation: Bob just came from a hot air balloon ride. On his way home he saw two balloons, balloon A and balloon B. Balloon A was flat, but balloon B was inflated. He was wondering how balloons go up so effortlessly.  Answer this question please: Would balloon B have faster or slower inside air movement than balloon A?
----
Answer: faster


Q: I can use this background: 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.  Now, I have a new situation: Greg is studying the environmental impact of agriculture. He noticed that in his own state a lake near agricultural lands has been declared as a dead zone. For his study Greg labeled this zone as zone A. Then he found near a national park in his state a lake is not declared as a dead zone. To further his study he labeled this zone as zone B.  Answer this question please: Would zone A have less or more oxygen than zone B?
A:
less
