Problem: Given the background: Noble gases are also used to fill the glass tubes of lighted signs like the one in the Figure below . Although noble gases are chemically nonreactive, their electrons can be energized by sending an electric current through them. When this happens, the electrons jump to a higher energy level. When the electrons return to their original energy level, they give off energy as light. Different noble gases give off light of different colors. Neon gives off reddish-orange light, like the word "Open" in the sign below. Krypton gives off violet light and xenon gives off blue light. and the situation: John wanted to make some lighted signs for his business. To that end, he chose noble gases, neon, krypton, and xenon. First, he kept the noble gases in containers. He called it step A. Then he passed electric current through them. He called it step B. In the process, he came up with three signs, sign A, sign B, and sign C. Sign A used neon. Sign B used krypton, and sign C used xenon. Answer the following question: In which step the the electrons would jump to higher energy level, step A or step B?

A: step B

Problem: Given the question: Given the background: Another example of incomplete dominance is with sickle cell anemia, a disease in which a blood protein called hemoglobin is produced incorrectly. This causes the red blood cells to have a sickle shape, making it difficult for these misshapen cells to pass through the smallest blood vessels. A person that is homozygous recessive ( ss ) for the sickle cell trait will have red blood cells that all have the incorrect hemoglobin. A person who is homozygous dominant ( SS ) will have normal red blood cells. and the situation: Terry and Jake are currently at a dinner party of a mutual friend. They are having a conversation while enjoying a glass of wine when suddenly on the TV there is a commercial about a new disease. This prompts Terry to mention that he actually has sickle cell anemia. Jake, not having the disease, is curious to learn more and asks Terry to explain more about it. Answer the following question: Is Terry's hemoglobin produced correctly or incorrectly?
++++++++++++++++++++++++++++++++
The answer is:
incorrectly

input question: Given the background: The jejunum is the second part of the small intestine, where most nutrients are absorbed into the blood. As shown in Figure below , the mucous membrane lining the jejunum is covered with millions of microscopic, fingerlike projections called villi (singular, villus). Villi contain many capillaries, and nutrients pass from the villi into the bloodstream through the capillaries. Because there are so many villi, they greatly increase the surface area for absorption. In fact, they make the inner surface of the small intestine as large as a tennis court! and the situation: Pete liked the human physiology so he started reading about the digestive system, especially about the jejunum. His colleague Fox, studied more about the stomach. Answer the following question: Which student read less about how nutrients pass from the villi into the bloodstream through the capillaries????
output answer: Fox

Given the background: Plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". This occurs in a type of glacier called a "valley glacier". As a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock. The freezing and thawing action of the ice enlarges, widens, or causes further cracks in the bedrock as it changes volume across the ice/water phase transition (a form of hydraulic wedging), gradually loosening the rock between the joints. This produces large pieces of rock called joint blocks. Eventually these joint blocks come loose and become trapped in the glacier. and the situation: Rob likes to visit high mountainous locations. Last year he visited the the Alps mountains in Austria. There he saw an unique type of glacier called valley glacier. This year he went further east to visit the Ural mountains in Russia. There he didn't see any valley glacier. Answer the following question: In which year Rob would observe quarrying effect, this year or last year?
----
Answer: last year

Q: Given the background: Water stratification is when water masses with different properties - salinity (halocline), oxygenation (chemocline), density (pycnocline), temperature (thermocline) - form layers that act as barriers to water mixing which could lead to anoxia or euxinia.[1] These layers are normally arranged according to density, with the least dense water masses sitting above the more dense layers. Water stratification also creates barriers to nutrient mixing between layers. This can affect the primary production in an area by limiting photosynthetic processes. When nutrients from the benthos cannot travel up into the photic zone, phytoplankton may be limited by nutrient availability. Lower primary production also leads to lower net productivity in waters.[2] and the situation: High lake had a lot of fresh and salt water mixing, therefore presented layers of stratified water.The water was poor in nutrients.Low lake had no such problems and it was a very abundant and prolific fishing spot. Answer the following question: Which lake had less dense layers of water?
A: Low lake

[Q]: Given the background: The device in the circuit in Figure above is an ammeter. It measures the current that flows through the wire. The faster the magnet or coil moves, the greater the amount of current that is produced. If more turns were added to the coil, this would increase the strength of the magnetic field as well. If the magnet were moved back and forth repeatedly, the current would keep changing direction. In other words, alternating current would be produced. This is illustrated in Figure below . and the situation: James is testing the strength of electromagnetic fields. He takes two lengths of copper wire and coils them. His first coil, A, has a weaker magnetic field than his second coil, B. Answer the following question: Given a very stong current is flowing through a wire, will an ammeter connected to the wire's magnet move fast or slow?
****
[A]:
fast
