You are given a new situation: Ben and Jack both loved microorganisms. Jack decided to study more about lactic fermentation, while Ben decided to study more about protozoa. and a hint : Animals and some bacteria and fungi carry out lactic acid fermentation. Lactic acid is a waste product of this process. Our muscles perform lactic acid fermentation during strenuous exercise, since oxygen cannot be delivered to the muscles quickly enough. The buildup of lactic acid is believed to make your muscles sore after exercise. Bacteria that produce lactic acid are used to make cheese and yogurt. The lactic acid causes the proteins in milk to thicken. Lactic acid also causes tooth decay, because bacteria use the sugars in your mouth for energy. Please answer this question : Which person read more about fungi that carry out lactic acid fermentation?

Answer: Jack

Q: You are given a new situation: Two meteorologists were good friends and discussed diverse issues weekly. This week they will talk again. Tim read about the Greenhouse Effect while Norm read about the mini-Ice ages. and a hint : Greenhouse Effect: The solar energy reaching the surface of the Earth is concentrated in short wavelengths, which can easily penetrate the greenhouse gases, such as carbon dioxide and methane. The Earth, however, is cooler than the sun and it radiates its heat in the form of energy in the far infrared range. These longer wavelengths are partially absorbed by the greenhouse gases and some of the solar heat is returned to Earth. At a certain temperature these processes are in equilibrium and the surface temperature of the Earth is stable. However, if more greenhouse gases are put in the atmosphere the amount of trapped terrestrial radiation increases, leading to an increase in global temperature. Please answer this question : Which friend learned more about solar energy reaching the surface of the Earth?
A: Tim

Question: You are given a new situation: Keith is a physician with the city hospital. He noticed that reactions inside human body happen in different rates. He specifically noticed two cases, case A and case B. In case A enzymes were present, but in case B enzymes were not present. and a hint : Enzymes increase the rate of chemical reactions by reducing the amount of activation energy needed for reactants to start reacting. One way this can happen is modeled in the Figure below . Enzymes aren't changed or used up in the reactions they catalyze, so they can be used to speed up the same reaction over and over again. Each enzyme is highly specific for the particular reaction is catalyzes, so enzymes are very effective. A reaction that would take many years to occur without its enzyme might occur in a split second with the enzyme. Enzymes are also very efficient, so waste products rarely form. Please answer this question : Would the required activation energy be higher or lower in case A than in case B?
Answer: lower

[Q]: You are given a new situation: A scientist named Kathy walks into her office to see two signs filled with noble gasses plugged into the wall and hanging above her desk. There is a large sign filled with neon and a small sign filled with krypton. Confused, she looks around to see if there's any clue as to who put them there. Seeing nobody, she flips the light switch on and walks in. Upon flipping the light switch, only the large sign lights up. Even though they are clearly both plugged in, the small sign isn't turning on. Kathy leaves her office to find someone to ask who put these random signs up in her room. and a hint : 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. Please answer this question : If properly working, which sign would give off a red glow?
****
[A]: large sign

input: Please answer the following: You are given a new situation: Tom and Jacob are carrying Geiger counters through an old abandoned city near a nuclear plant. Tom walks into a hotel and looks around at all the paintings and old couches in the lobby. His Geiger counter remains silent, but as he walks up the stairs toward the second floor it starts to slowly but steadily make more sound. Jacob steps into a grocery store when his Geiger counter immediately starts making lots of noise, but his device starts to drop off in sound as he walks toward the freezer in the back of the store. and a hint : One reason radiation is dangerous is that it can't be detected with the senses. You normally can't see it, smell it, hear it, or feel it. Fortunately, there are devices such as Geiger counters that can detect radiation. A Geiger counter, like the one in Figure below , has a tube that contains atoms of a gas. If radiation enters the tube, it turns gas atoms to ions that carry electric current. The current causes the Geiger counter to click. The faster the clicks occur, the higher the level of radiation. Please answer this question : Is Jacob detecting an increase or decrease in radiation in the direction he is walking?
++++++++++
output: decrease

You are given a new situation: Mark has just graduated high school and is going to visit his grandpa, Tom, over the summer for a couple days. Since Tom is retired, he often has plenty of time to go fishing, and he even has a small cabin by the lake. The two men are planning to spend several days at the cabin cooking, fishing, chopping firewood to make fires and just general outdoor activities. and a hint : Old age begins in the mid-60s and lasts until the end of life. Many people over 65 have retired from work, freeing up their time for hobbies, grandchildren, and other interests. Stamina, strength, reflex time, and the senses all decline during old age, and the number of brain cells decreases as well. The immune system becomes less efficient, increasing the risk of serious illnesses such as cancer and pneumonia. Diseases such as Alzheimer's disease that cause loss of mental function also become more common. Please answer this question : Does Mark have more or less stamina than Tom?
