Please answer this: I read this background article the other day: Geologists study earthquake waves to "see" Earth's interior. Waves of energy radiate out from an earthquake's focus. These waves are called seismic waves ( Figure below ). Seismic waves go different speeds through different materials. They change speed when they go from one type of material to another. This causes them to bend. Some seismic waves do not travel through liquids or gases. They just stop. Scientists use information from seismic waves to understand what makes up the Earth's interior. I am facing a new situation today: Mary is studying the seismic waves of a recent earthquake from 2 locations around its focus. She notes at point A the waves are easily detectable. at point B the waves are unable to be read at all, as if they just stopped. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which area is likely to have underground water, point A or point B.

Answer: B
Problem: I read this background article the other day: Sometimes muscles and tendons get injured when a person starts doing an activity before they have warmed up properly. A warm up is a slow increase in the intensity of a physical activity that prepares muscles for an activity. Warming up increases the blood flow to the muscles and increases the heart rate. Warmed-up muscles and tendons are less likely to get injured. For example, before running or playing soccer, a person might jog slowly to warm muscles and increase their heart rate. Even elite athletes need to warm up ( Figure below ). I am facing a new situation today: Two soccer players had a friendly match one on one after work. Paul had plenty of time to do his warm up properly, but John got there late and didn't warm up. Paul won the match. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which player was less exposed to tendon injuries?

A: Paul
Problem: Given the question: I read this background article the other day: The quantity of small plastic fragments floating in the north-east Pacific Ocean increased a hundredfold between 1972 and 2012.Marine pollution is a generic term for the harmful entry into the ocean of chemicals or particles. The main culprits are those using the rivers for disposing of their waste. The rivers then empty into the ocean, often also bringing chemicals used as fertilizers in agriculture. The excess of oxygen-depleting chemicals in the water leads to hypoxia and the creation of a dead zone.Marine debris, also known as marine litter, is human-created waste that has ended up floating in a lake, sea, ocean, or waterway. Oceanic debris tends to accumulate at the center of gyres and coastlines, frequently washing aground where it is known as beach litter.In addition, the Pacific Ocean has served as the crash site of satellites, including Mars 96, Fobos-Grunt, and Upper Atmosphere Research Satellite. I am facing a new situation today: Tim and Joe were two friends living near two different oceans. Tim lived on the Pacific coast while Joe lived on the Atlantic coast. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which friend sees fewer debris floating in the ocean?
++++++++++++++++++++++++++++++++
The answer is:
Joe
input question: I read this background article the other day: When the Moon is at first quarter or third quarter, the Sun and Moon are separated by 90 when viewed from the Earth, and the solar tidal force partially cancels the Moon's tidal force. At these points in the lunar cycle, the tide's range is at its minimum; this is called the neap tide, or neaps. Neap is an Anglo-Saxon word meaning "without the power", as in forganges nip (forth-going without-the-power).Spring tides result in high waters that are higher than average, low waters that are lower than average, 'slack water' time that is shorter than average, and stronger tidal currents than average. Neaps result in less extreme tidal conditions. There is about a seven-day interval between springs and neaps. I am facing a new situation today: Rob was in the East Coast for a month. He had the good opportunity to see various tidal conditions. First he saw the spring tide, which he noted as case A. About a week later he saw the neap tide. He noted that as case B. Rob got curious about the science behind various tidal conditions. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: In which case the slack water time would be shorter, case A or case B????
output answer: case A
I read this background article the other day: The body's second line of defense against pathogens includes the inflammatory response. If bacteria enter the skin through a scrape, the area may become red, warm, and painful. These are signs of inflammation. Inflammation is one way the body reacts to infections or injuries. Inflammation is caused by chemicals that are released when skin or other tissues are damaged. The chemicals cause nearby blood vessels to dilate, or expand. This increases blood flow to the damaged area, which makes the area red and slightly warm. The chemicals also attract white blood cells called neutrophils to the wound and cause them to leak out of blood vessels into the damaged tissue. I am facing a new situation today: Two medical school students named Dan and Bob learned about the human immune system. Dan studied more about the subject, and became very interested to pursue it more in the future. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which student learned that the infected skin area may become painful?
----
Answer: Dan
Q: 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 more about ions moving from an area of lower to higher concentration?
A:
Andy
