I read this background article the other day: A: You could shake a bottle of cola and then open it. Shaking causes carbon dioxide to come out of the cola solution and change to a gas. The gas fizzes out of the bottle and spreads into the surrounding air, showing that its particles have enough kinetic energy to spread apart. Then you could tilt the open bottle and pour out a small amount of the cola on a table, where it will form a puddle. This shows that particles of the liquid have enough kinetic energy to slide over each other but not enough to pull apart completely. If you do nothing to the solid glass of the cola bottle, it will remain the same size and shape. Its particles do not have enough energy to move apart or even to slide over each other.  I am facing a new situation today: Michael wants to play a trick on his friend. He takes a bottle of soda, shakes it really well then puts it in the fridge. He then tells his friend if he wants something to drink there's some soda in the fridge. Michael's friend goes to the fridge and pulls out the bottle Michael just shook and opens it.  Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which will happen when Michael's friend opens the bottle. nothing or will it release carbon dioxide?
----
Answer: release carbon dioxide

Q: I read this background article the other day: In exercises such as weight lifting, skeletal muscle contracts against a resisting force (see Figure below ). Using skeletal muscle in this way increases its size and strength. In exercises such as running, the cardiac muscle contracts faster and the heart pumps more blood. Using cardiac muscle in this way increases its strength and efficiency. Continued exercise is necessary to maintain bigger, stronger muscles. If you don’t use a muscle, it will get smaller and weaker—so use it or lose it.  I am facing a new situation today: Bill and Bob were two brothers. they were both into physical exercise, but Bill chose weight lifting, and Bob running.  Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which brother had more muscles contract against a resisting force?
A: Bill

Question: I read this background article the other day: Groundwater salinization compromises buffering properties. Vegetation clearance, along with irrigation, causes serious issues. Irrigation increases the water table and mobilizes salts, and vegetation clearance allows it to come in contact with water habitats and vegetation. This stresses species not adapted to high salinity. High levels of salinity reduces water uptake in plants, by causing stomatal closure, reducing photosynthesis. Forests undergo decline in areas of high salinity and shallow groundwater depths because these conditions make them more susceptible to droughts. Forests undergo decline in areas of high salinity and shallow groundwater depths making them more susceptible to droughts.  I am facing a new situation today: In the sixteenth century the State of Michigan had forests all over. But that has long been gone.  Especially, in the state's northeast part the vegetation has been cleared in the twentieth century.  Wooded areas were replaced by farm lands. All these farmlands were under heavy Irrigation. At one time, in the sixteenth century, plant species like elm and oak used to be plentiful. We still had some elms and oaks in the twentieth century, but they were not great many in number.  Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Was the mobilized salts at increased or decreased level in northeast Michigan in the sixteenth century?
Answer: decreased level

[Q]: I read this background article the other day: In the U.S., the majority of electricity is produced by burning coal or other fossil fuels. This causes air pollution that harms the health of living things. The air pollution also causes acid rain and contributes to global warming. In addition, fossil fuels are nonrenewable resources, so if we keep using them, they will eventually run out. The main advantage of nuclear energy is that it doesn’t release air pollution or cause the other environmental problems associated with the burning of fossil fuels. On the other other hand, radioactive elements are nonrenewable like fossil fuels and could eventually be used up.  I am facing a new situation today: Two competing countries used different energy sources to produce their electricity. Turkey used mostly fossil fuels, while Greece used nuclear power.  Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which country caused less acid rain?
****
[A]: Greece

input: Please answer the following: I read this background article the other day: Hemophilia is the name of a group of hereditary diseases that affect the body's ability to control blood clotting. Hemophilia is caused by a lack of clotting factors in the blood. Clotting factors are normally released by platelets. Since people with hemophilia cannot produce clots, any cut can put a person at risk of bleeding to death. The risk of internal bleeding is also increased in hemophilia, especially into muscles and joints. This disease affected the royal families of Europe.  I am facing a new situation today: Two twin sisters were taken to the doctor's office by their parents. It turned out that Mary had hemophilia while Ann didn't have any blood disease.  Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which sister had more clotting factors in the blood?
++++++++++
output: Ann

I read this background article the other day: Sodium and potassium are two of the most important elements in living things. They are present mainly as positively charged ions dissolved in water. The sodium-potassium pump moves sodium ions (Na + ) out of the cell and potassium ions (K + ) into the cell. In both cases, the ions are moving from an area of lower to higher concentration. Energy in ATP is needed for this "uphill" process. Figure below shows how this pump works. Trace these steps from left to right in the figure  I am facing a new situation today: Ben and Andy studied minerals and micro-nutrients. Ben studied more about magnesium, zinc and molybdenum, while his buddy Andy studied about sodium and potassium.  Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which person studied less about moving sodium ions (Na + ) out of the cell?
----
Answer:
Ben
