Q: John is a biologist. Last summer, he was studying the evolution of two different salamander species, species A and species B. Species A salamander was Gold-striped salamander while species B salamander was fire salamander. He found it interesting that they took different approaches to adapt to different habitats. Given the paragraph above, please answer correctly the following question: Which species would be less successful in reproduction, Species A or species B? Hint: Consider the antlers of the Irish elk, (often supposed to be far too large; in deer antler size has an allometric relationship to body size). Obviously, antlers serve positively for defence against predators, and to score victories in the annual rut. But they are costly in terms of resource. Their size during the last glacial period presumably depended on the relative gain and loss of reproductive capacity in the population of elks during that time. As another example, camouflage to avoid detection is destroyed when vivid coloration is displayed at mating time. Here the risk to life is counterbalanced by the necessity for reproduction.Stream-dwelling salamanders, such as Caucasian salamander or Gold-striped salamander have very slender, long bodies, perfectly adapted to life at the banks of fast small rivers and mountain brooks. Elongated body protects their larvae from being washed out by current. However, elongated body increases risk of desiccation and decreases dispersal ability of the salamanders; it also negatively affects their fecundity. As a result, fire salamander, less perfectly adapted to the mountain brook habitats, is in general more successful, have a higher fecundity and broader geographic range.
A: species A
Question: Two groups of soldiers started different training programs. Blue group did weight training for 3 months, while Brown group ran 3 miles a day for three months. The Captain observed different results on each group. Given the paragraph above, please answer correctly the following question: Which group didn't have their hearts pumping more blood while training? Hint: In exercises such as weight lifting, skeletal muscle contracts against a resisting force (see Figure below ). Using skeletal muscle in this way increases its size and strength. In exercises such as running, the cardiac muscle contracts faster and the heart pumps more blood. Using cardiac muscle in this way increases its strength and efficiency. Continued exercise is necessary to maintain bigger, stronger muscles. If you don't use a muscle, it will get smaller and weakerso use it or lose it.
Answer: Blue
[Q]: Two brothers loved geology. Bob studied sedimentary rocks while Dan studied about earthquakes and their location. Given the paragraph above, please answer correctly the following question: Which brother studied more about rocks breaking as a result of stress buildup? Hint: Almost all earthquakes occur at plate boundaries. All types of plate boundaries have earthquakes. Convection within the Earth causes the plates to move. As the plates move, stresses build. When the stresses build too much, the rocks break. The break releases the energy that was stored in the rocks. The sudden release of energy creates an earthquake. During an earthquake the rocks usually move several centimeters or rarely as much as a few meters. Elastic rebound theory describes how earthquakes occur ( Figure below ).

input: Please answer the following: A large group of bears lives in a forest. Over time the climate of the forest changes and becomes very cold. Some of the bears have thicker fur while some of the others have thinner fur. Due to the cold weather the bears with thinner fur die earlier. Also the bears with thicker fur have an easier time finding mates. Because of this the bears with thick fur have their traits passed on more often and bears with thin fur appear less and less in the population Given the paragraph above, please answer correctly the following question: Which trait would be passed on to future generations if the forest became even colder, thick fur or thin fur? Hint: New species develop naturally through the process of natural selection . Due to natural selection, organisms with traits that better enable them to adapt to their environment will tend to survive and reproduce in greater numbers. Natural selection causes beneficial heritable traits to become more common in a population and unfavorable heritable traits to become less common. For example, a giraffe's neck is beneficial because it allows the giraffe to reach leaves high in trees. Natural selection caused this beneficial trait to become more common than short necks.

output: thick fur
Please answer this: David is interested in how electricity works. One day he had two electric charges to investigate, charge A and charge B - both of the charges were negative. He also had two electric fields, field C and field D. He noticed that electric charges were moving from field C to field D. Given the paragraph above, please answer correctly the following question: If the potential energy between charge A and charge B decreases, are they closer or farther? Hint: Electric potential energy comes from the position of a charged particle in an electric field. For example, when two negative charges are close together, they have potential energy because they repel each other and have the potential to push apart. If the charges actually move apart, their potential energy decreases. Electric charges always move spontaneously from a position where they have higher potential energy to a position where they have lower potential energy. This is like water falling over a dam from an area of higher to lower potential energy due to gravity.

Question: two buildings had different tenants. Building Y had many seniors over 65 years of age, and building X had individuals under 65 years old. Given the paragraph above, please answer correctly the following question: Which building had more people that have more time for their hobbies? Hint: Old age begins in the mid-60s and lasts until the end of life. Most 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.
Answer:
Building Y
