Q: You are given a new situation: Two neighboring planets identical to Earth in size and atmospheric conditions behaved differently towards their environments. Planet A emitted a lot of air pollution, destroying its ozone layer, while Planet B respected the environment and used ecological products. and a hint : 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. It's rate of loss has slowed with restrictions on pollutants, but it is still at risk. Please answer this question : Which planet used more coolants?
A: Planet A

Question: You are given a new situation: Two students studied animal behavior for the biology class. Ned studied more about predators, while Kim studied more about herbivores. and a hint : Predators play an important role in an ecosystem. For example, if they did not exist, then a single species could become dominant over others. Grazers on a grassland keep grass from growing out of control. Predators can be keystone species . These are species that can have a large effect on the balance of organisms in an ecosystem. For example, if all of the wolves are removed from a population, then the population of deer or rabbits may increase. If there are too many deer, then they may decrease the amount of plants or grasses in the ecosystem. Decreased levels of producers may then have a detrimental effect on the whole ecosystem. In this example, the wolves would be a keystone species. Please answer this question : Which student studied more about keystone species?
Answer: Ned

[Q]: You are given a new situation: Two colleagues gave blood for an emergency. Ned got infected with HIV because they re-used a needle. His friend Nate was not infected. and a hint : The Human Immunodeficiency Virus ( HIV ) is the virus that causes Acquired Immunodeficiency Syndrome ( AIDS ). Most researchers believe that the HIV originated in sub-Saharan Africa during the 20th century. HIV is transmitted by sexual contact and by contact with infected bodily fluids, such as blood, semen, breast milk, and vaginal secretions. It is also passed from mother to fetus. HIV is now a pandemic , with an estimated (as of 2008) 38.6 million people now living with the disease worldwide. It is estimated that AIDS has killed more than 25 million people since it was first recognized in 1981. For further information about HIV/AIDS, see the CDC (Centers for Disease Control and Prevention) web site at http://www.cdc.gov/hiv/resources/factsheets/ . Please answer this question : Which colleague had a virus that is transmitted by contact with infected breast milk?
****
[A]: Ned

input: Please answer the following: You are given a new situation: Albert is a scientist who travels the planet looking for new species to discover and analyze. While on a safari in Australia, Albert discovered two new species of live-bearing tetrapods. In the first species, species A, the adult individuals had high body mass on average. In the second species, species B, the adult individuals had low body mass on average. and a hint : From the data he collected and documented, Aristotle inferred quite a number of rules relating the life-history features of the live-bearing tetrapods (terrestrial placental mammals) that he studied. Among these correct predictions are the following. Brood size decreases with (adult) body mass, so that an elephant has fewer young (usually just one) per brood than a mouse. Lifespan increases with gestation period, and also with body mass, so that elephants live longer than mice, have a longer period of gestation, and are heavier. As a final example, fecundity decreases with lifespan, so long-lived kinds like elephants have fewer young in total than short-lived kinds like mice. Please answer this question : Which species will have smaller broods?
++++++++++
output: species A

Please answer this: You are given a new situation: Catherine is throwing her friend a birthday party and is starting to put up decorations. She has finished hanging streamers and now she has to fill the balloons. Having never used a helium tank before, she wants to test how much to fill each balloon. and a hint : All fluids exert pressure like the air inside a tire. The particles of fluids are constantly moving in all directions at random. As the particles move, they keep bumping into each other and into anything else in their path. These collisions cause pressure, and the pressure is exerted equally in all directions. When particles are crowded together in one part of an enclosed space, such as the air particles first entering a tire, they quickly spread out to fill all the available space. That's because particles of fluids always move from an area of higher pressure to an area of lower pressure. This explains why air entering a tire through a tiny opening quickly fills the entire tire. Please answer this question : If one balloon is smaller than another will it require more or less helium to fill?
++++++++
Answer: less

Question: You are given a new situation: John is learning more about different cultures and people around the world. He noticed that people have different skin colors. To learn more about the science behind skin colors he categorized the skin colors into two broad groups, case D and case L. Case D is represented by darker skin and case L is represented by lighter skin. and a hint : The epidermis also contains melanocytes , which are cells that produce melanin. Melanin is the brownish pigment that gives skin much of its color. Everyone has about the same number of melanocytes, but the melanocytes of people with darker skin produce more melanin. The amount of melanin produced is determined by heredity and exposure to UV light, which increases melanin output. Exposure to UV light also stimulates the skin to produce vitamin D . Because melanin blocks UV light from penetrating the skin, people with darker skin may be at greater risk of vitamin D deficiency. Please answer this question : Would case D produce more or less melanin than case L?
Answer:
more
