Please answer this: Because of human activities, there is more carbon dioxide in the atmosphere today than in the past hundreds of thousands of years. Burning fossil fuels and has released great quantities of carbon dioxide into the atmosphere. Cutting forests and clearing land has also increased carbon dioxide into the atmosphere because these activities reduce the number of autotrophic organisms that use up carbon dioxide in photosynthesis. In addition, clearing often involves burning, which releases carbon dioxide that was previously stored in autotrophs. When comparing village A from ten thousand years ago to village B from today, we reached the conclusion that today's villagers release much more carbon into the atmosphere by their activities. Which village burned fewer fossil fuels?
++++++++
Answer: village A

Problem: The primary role of red blood cells in the circulatory system is to transport oxygen to the tissues. The actual carrier of oxygen molecules is the protein hemoglobin, which binds to the oxygen and moves it throughout the body, releasing it in areas where the concentration of dissolved oxygen is low. A certain mutation in the gene for hemoglobin causes a slight change in the structure of this crucial protein, resulting in a disease called sickle-cell anemia. For people with this mutation, the hemoglobin produced by their red blood cells has a tendency to clump together, distorting the shape of the red blood cells and giving rise to the crescent-shaped cells seen above. By understanding the changes in structure that are the underlying cause of this disease, we have developed various ways to treat and manage this illness. Doctor Jones studied two teams of workers. Team one had healthy people with normal red blood cell levels, but team two had people with sickle-cell anemia. the differences in health parameters were amazing and obvious. Which team had people getting less oxygen to their cells?

A: team two

Problem: Given the question: Some individuals have a specific mutation in the primary sequence of their hemoglobin molecules that causes them to aggregate, resulting in a deformation of their red blood cells. This abnormality is genetic in nature. A person may inherit the gene from one parent and have sickle cell trait (only some of the hemoglobin is hemoglobin S), which is usually not life-threatening. Inheriting the gene from both parents will result in sickle cell disease, which is a very serious condition. Pete and Mike were two brothers. Pete had no health problems, while Mike inherited the sickle cell trait. Mike had adjacent health problems. Which brother didn't have molecules of hemoglobin that aggregate?
++++++++++++++++++++++++++++++++
The answer is:
Pete

input question: A vapor light produces visible light by electroluminescence. The bulb contains a small amount of solid sodium or mercury as well as a mixture of neon and argon gases. When an electric current passes through the gases, it causes the solid sodium or mercury to change to a gas and emit visible light. Sodium vapor lights, like these streetlights, produce yellowish light. Mercury vapor lights produce bluish light. Vapor lights are very bright and energy efficient. The bulbs are also long lasting. James is driving down the street in his town. For some reason today hes very curious about the things that he sees. He looks around as hes driving and the street lights catch his attention. He realizes that he's never seen someone changing the bulbs in a street light. He also wonders if its a film on the light that makes them have that color or something inside. Given a vapor light and a regular light bulb, which one is more energy efficient, the vapor light or the regular light bulb????
output answer: vapor light

In slippery conditions some riders prefer to ride fixed because they believe the transmission provides increased feedback on back tire grip. However, there is also an increased risk of loss of control in such conditions. This is especially so when taking into account the large number of riders who ride brakeless. These riders must brake entirely through the drivetrain. Ideally this is done by resisting the forward motion of the pedals, shedding speed while the bike is still moving. Alternatively, though far less efficiently, one can brake by stopping the motion of the pedals in mid-rotation, causing the rear wheel to lock in place, allowing the bicycle to skid and slow down from kinetic friction (see below).[22] Descending any significant gradient is more difficult as the rider must spin the cranks at high speed (sometimes at 170 rpm or more), or use the brakes to slow down. Some consider that the enforced fast spin when descending increases suppleness or flexibility, which is said to improve pedalling performance on any type of bicycle; however the performance boost is negligible compared to the benefits of riding a free wheel.[23] Two villages are inhabited by lots of people that ride bicycles. Hill village is located on a mountain and gets lots of rain, and Low village is situated in a valley, and has more sunny days. Which village has more dangerous cycling conditions?
----
Answer: Hill

Q: Storing large volumes of data When storing XML to either file or database, the volume of data a system produces can often exceed reasonable limits, with a number of detriments: the access times go up as more data is read, CPU load goes up as XML data takes more power to process, and storage costs go up. By storing XML data in Fast Infoset format, data volume may be reduced by as much as 80 percent. Bob works for a data storage company. He has now three projects, project A, project B, and project C, simultaneously going on. All of them involves storing XML data. Project A has small volume of data, but project B and project C has large volume of data. He applied Fast Infoset format for project B, but didn't apply that format for project C. Would project B have reduced or enlarged data volume than porject C?
A:
reduced
