input question: I read this background article the other day: The lungs of mammals are unique in having alveoli . These are tiny, sac-like structures. Each alveolus is surrounded by a network of very small blood vessels (see Figure below ). Because there are millions of alveoli in each lung, they greatly increase the surface area for gas exchange between the lungs and bloodstream. Human lungs, for example, contain about 300 million alveoli. They give the lungs a total surface area for gas exchange of up to 90 square meters (968 square feet). That's about as much surface area as one side of a volleyball court! I am facing a new situation today: Two six graders learned about the lives of animals. Lori learned more about fish, while Dan learned more about mammals. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which student learned less about the lungs of mammals????
output answer: Lori
I read this background article the other day: Cholesterol can't dissolve in the blood. It has to be transported to and from the cells by carriers called lipoproteins. Low-density lipoprotein, or LDL, is known as "bad" cholesterol. High-density lipoprotein (HDL) is known as good cholesterol. When too much LDL cholesterol circulates in the blood, it can slowly build up in the inner walls of the arteries that feed the heart and brain. Together with other substances, it can form plaque, and lead to atherosclerosis. If a clot forms and blocks a narrowed artery, a heart attack or stroke can result. Cholesterol comes from the food you eat as well as being made by the body. To lower bad cholesterol, a diet low in saturated fat and dietary cholesterol should be followed. Regular aerobic exercise also lowers LDL cholesterol and increases HDL cholesterol. I am facing a new situation today: John is a doctor with the local hospital. Earlier today, he was seeing two patients, patient A and patient B. John found out that patient A had more LDL, but patient B had more HDL. He now needs to determine correct treatment for them. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Would patient A have higher or lower risk of heart attack than patient B?

Answer: higher
Q: I read this background article the other day: The lungs of mammals are unique in having alveoli . These are tiny, sac-like structures.

That's about as much surface area as one side of a volleyball court! I am facing a new situation today: David is investigating the breathing process of different organisms. He found that humans have alveoli to help them with gas exchange. He got curious about other organisms that do not have alveoli. To compare these two groups he labeled organisms with alveoli as group A and organisms without alveoli as group B. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which group may not have network of small blood vessels in the lungs, group A or group B ?
A: group B
Question: I read this background article the other day: Klinefelter's syndrome is caused by the presence of one or more extra copies of the X chromosome in a male's cells. Extra genetic material from the X chromosome interferes with male sexual development, preventing the testicles from functioning normally and reducing the levels of testosterone. Triple X syndrome (trisomy X) results from an extra copy of the X chromosome in each of a female's cells. Females with trisomy X have a lower IQ than their siblings. Turner syndrome results when each of a female's cells has one normal X chromosome and the other sex chromosome is missing or altered. The missing genetic material affects development and causes the characteristic features of the condition, including short stature and infertility. I am facing a new situation today: David is a physician with the children's hospital. He is seeing four patients, patient A, patient B, patient C, and patient D. Patient A is a male with Klinefelter's syndrome. Patient B is female with Turner syndrome. Patient C is a male and does not have any of these illnesses. Patient D is a female and she too does not have any of these illnesses. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Would patient A have higher or lower level of testosterone than patient C?
Answer: lower
[Q]: I read this background article the other day: Further heating then adds energy to the liquid particles, increasing their speed, kinetic energy, and temperature. This is the second slope on the curve. Once the particles are energetic enough to completely break free of each other, they start to enter the gas phase. Boiling occurs at the second plateau of this curve, and the temperature at this point is referred to as the boiling point . Again, the added heat is being used to break up the interactions between particles instead of increasing their kinetic energy, so no temperature increase is observed until all particles are in the gas phase. Finally, adding even more energy will further speed up the gas particles, increasing the kinetic energy and temperature of the substance. I am facing a new situation today: Will is doing some testing with heat. He freezes some water in a cup then takes the ice cube and puts it into a pot. He places a thermometer on the ice cube and takes readings. To his surprise, the temperature on the thermometer is stable the entire time it's on the ice cube, Then the ice cube completely melts. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Will the temperature reading on the thermometer go beyond the boiling point while resting in the water before the water turns into a gas, yes or no?

[A]: no
Problem: Given the question: 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: A team of researchers named Alpha did some research on the inflammatory response in humans for a science contest. A competing team called Omega did research on the human genome. Team Omega lost. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which team studied less about bacteria entering the skin through a scrape?
++++++++++++++++++++++++++++++++
The answer is:
Omega
