input: Please answer the following: I read this background article the other day: The above example shows how science generally advances. New evidence is usually used to improve earlier ideas rather than entirely replace them. In this way, scientists gradually refine their ideas and increase our understanding of the world. On the other hand, sometimes science advances in big leaps. This has happened when a scientist came up with a completely new way of looking at things. For example, Albert Einstein came up with a new view of gravity. He said it was really just a dent in the fabric of space and time. I am facing a new situation today: This year scientist found concrete evidence of existence of black holes by taking photograph of one. Unfortunately, the originator of black hole theory, Stephen Hawking, was never awarded a Nobel prize despite letting science advance in big leap because his theory could not be verified during his lifetime. On the other hand, scientist B has received Nobel prize because he has based his theory on the earlier theory of scientist A. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which scientist might have improved an earlier idea, scientist A or scientist B?
++++++++++
output: scientist B

input: Please answer the following: I read this background article the other day: At the mid-oceanic ridges, two tectonic plates diverge from one another as new oceanic crust is formed by the cooling and solidifying of hot molten rock. Because the crust is very thin at these ridges due to the pull of the tectonic plates, the release of pressure leads to adiabatic expansion (without transfer of heat or matter) and the partial melting of the mantle, causing volcanism and creating new oceanic crust. Most divergent plate boundaries are at the bottom of the oceans; therefore, most volcanic activity on the Earth is submarine, forming new seafloor. Black smokers (also known as deep sea vents) are evidence of this kind of volcanic activity. Where the mid-oceanic ridge is above sea-level, volcanic islands are formed; for example, Iceland. I am facing a new situation today: Two oceans have divergent plate boundaries at the bottom of their floor. The Arctic ocean has a single dormant divergent plate, while the Pacific ocean has seven diverging tectonic plates under its waters. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which ocean experiences more adiabatic expansion?
++++++++++
output: Pacific

input: Please answer the following: I read this background article the other day: One of the main causes of extinction is introduction of exotic species into an environment. These exotic and new species can also be called invasive species or non-native species . These non-native species, being new to an area, may not have natural predators in the new habitat, which allows their populations to easily adapt and grow. Invasive species out-compete the native species for resources. Sometimes invasive species are so successful at living in a certain habitat that the native species go extinct ( Figure below ). I am facing a new situation today: India decided to introduce several exotic species into their environment, while Singapore was very protective of its native species. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which country didn't observe that non-native species easily adapt and grow?
++++++++++
output: Singapore

input: Please answer the following: I read this background article the other day: A baby is born with zones of cartilage in its bones that allow growth of the bones. These areas, called growth plates , allow the bones to grow longer as the child grows. By the time the child reaches an age of about 18 to 25 years, all of the cartilage in the growth plate has been replaced by bone. This stops the bone from growing any longer. Even though bones stop growing in length in early adulthood, they can continue to increase in thickness throughout life. This thickening occurs in response to strain from increased muscle activity and from weight-lifting exercises. I am facing a new situation today: Two brothers, Tom, aged 26, and Paul, aged 16, started weight-lifting to gain more muscle mass. Three years later they were 20-25 lbs. heavier. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which brother had active growth cartilages?
++++++++++
output:
Paul
