Please answer this: Background: Unfortunately, the layer of good ozone is being destroyed by air pollution. The chief culprits are chlorine and bromine gases. They are released in aerosol sprays, coolants, and other products. Loss of ozone has created an ozone hole over Antarctica. Ozone depletion results in higher levels of UV radiation reaching Earth. In humans, this increases skin cancers and eye cataracts. It also disturbs the nitrogen cycle, kills plankton, and disrupts ocean food webs. The total loss of the ozone layer would be devastating to most life. Its rate of loss has slowed with restrictions on pollutants, but it is still at risk. Paragraph: Two researchers studied air quality over the North Pole, and over Antarctica. Dan was more fond of the south pole, so he studied Antarctica, while Colt liked reading about the North Pole. Given the paragraph above, please answer correctly the following question: Which researcher learned more about bromine gases?
++++++++
Answer: Dan

Problem: Background: 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! Paragraph: Two six graders learned about the lives of animals. Lori learned more about fish, while Dan learned more about mammals. Given the paragraph above, please answer correctly the following question: Which student learned less about gas exchange between the lungs and bloodstream?

A: Lori

Problem: Given the question: Background: A mycorrhiza (Greek for "fungus roots") is a symbiotic association between a fungus and the roots of a plant. In a mycorrhizal association, the fungus may colonize the roots of a host plant by either growing directly into the root cells, or by growing around the root cells. This association provides the fungus with relatively constant and direct access to glucose, which the plant produces by photosynthesis. The mycelia of the fungi increase the surface area of the plant's root system. The larger surface area improves water and mineral nutrient absorption from the soil. Paragraph: Two plants of the same type are growing near the outskirts of the Jorah forest. The first plant, colored red, is healthy and has no fungus on it. The other plant, colored black, has a fungus growing on the roots of it. These plants have been around for centuries and if crushed into a powder actually make a nice seasoning to add to a meal. Given the paragraph above, please answer correctly the following question: Which color plant is sharing access to its glucose?
++++++++++++++++++++++++++++++++
The answer is:
black

input question: Background: No doubt you already have a good idea of what temperature is. You might say that it's how warm or cool something feels. In physics, temperature is defined as the average kinetic energy of the particles of matter. When particles of matter move more quickly, they have more kinetic energy, so their temperature is higher. With a higher temperature, matter feels warmer. When particles move more slowly, they have less kinetic energy on average, so their temperature is lower. With a lower temperature, matter feels cooler. Paragraph: David is trying to understand temperature and the science behind it. He took two objects, object A and object B, to his physics professor. Object A had higher temperature, but object B had lower temperature. His physics professor explained him why one object's temperature was higher while other object's temperature was lower. Given the paragraph above, please answer correctly the following question: Would particles move slower or faster in object A than in object B????
output answer: faster

Background: If a solution has a higher concentration of hydronium ions than pure water, it has a pH lower than 7. A solution with a pH lower than 7 is called an acid . As the hydronium ion concentration increases, the pH value decreases. Therefore, the more acidic a solution is, the lower its pH value is. Did you ever taste vinegar? Like other acids, it tastes sour. Stronger acids can be harmful to organisms. For example, stomach acid would eat through the stomach if it were not lined with a layer of mucus. Strong acids can also damage materials, even hard materials such as glass. Paragraph: Alexiev and Sabrina were enthusiastic chemistry students completing the first experiment of their new course. They both started the experiment with pure water, and had to perform different experimental protocols to make changes to the water. At the end of the experiment, both of them measured the concentration of hydronium ions present in their reaction mixtures. Alexiev had a high concentration of hydronium ions present, while Sabrina had a low concentration present in her mixture. Given the paragraph above, please answer correctly the following question: Which person's mixture, Alexiev's or Sabrina's, would taste less sour at the end?
----
Answer: Sabrina's

Q: Background: The ionization energies of the representative elements generally decrease from top to bottom within a group. This trend is explained by the increase in size of the atoms within a group. The valence electron that is being removed is further from the nucleus in the case of a larger atom. The attractive force between the valence electron and the nucleus weakens as the distance between them increases and as the shielding effect increases, resulting in a lower ionization energy for the larger atoms within a group. Although the nuclear charge is increased for larger atoms, the shielding effect also increases due to the presence of a larger number of inner electrons. This is particularly easy to see in the alkali metals, where the single valence electron is shielded by all of the inner core electrons. Paragraph: Joel has just started his first day working as a scientist in a laboratory. The first task he was given is to look at two atoms and to jot down as much information about the two as he can. First, he needs to come up with an identification for these atoms. Since he is new, he decides to keep it professional and simply call the larger of the two atoms "atom L" and the smaller one "atom S". Now that he's taken care of that he can get down to work. Given the paragraph above, please answer correctly the following question: Which atom's removed valence electron is closer to its own nucleus?
A:
atom S
