input question: Given the background: Marine pollution is a generic term for the entry into the ocean of potentially hazardous chemicals or particles. The biggest culprits are rivers and with them many agriculture fertilizer chemicals as well as livestock and human waste. The excess of oxygen-depleting chemicals leads to hypoxia and the creation of a dead zone.Marine debris, which is also known as marine litter, describes human-created waste floating in a body of water. Oceanic debris tends to accumulate at the center of gyres and coastlines, frequently washing aground where it is known as beach litter. and the situation: Two cities situated on the shores of a large ocean polluted it in different ways. Truck city had an economy that was based on tourism, while Farm city was based on agriculture. Answer the following question: Which city caused less hypoxia????
output answer: Truck

input question: Given the background: The number of viruses in the oceans decreases further offshore and deeper into the water, where there are fewer host organisms.In January 2018, scientists reported that 800 million viruses, mainly of marine origin, are deposited daily from the Earth's atmosphere onto every square meter of the planet's surface, as the result of a global atmospheric stream of viruses, circulating above the weather system, but below the altitude of usual airline travel, distributing viruses around the planet.Like any organism, marine mammals are susceptible to viral infections. In 1988 and 2002, thousands of harbour seals were killed in Europe by phocine distemper virus. Many other viruses, including caliciviruses, herpesviruses, adenoviruses and parvoviruses, circulate in marine mammal populations. and the situation: John is a marine biologist. He was collecting samples from six locations in the ocean, location A, location B, location C, location D, location E, and location F. Location A was near the shore, but location B was farther offshore. Location C was in shallow water, but location D was deeper into the ocean. Location E was a habitat with very few organisms, but location F was a habitat full of organisms. Answer the following question: Would location D see less or more viruses than location C????
output answer: less

input question: Given the background: 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. and the situation: Two students from the same class, studies different types of animals. Bill studied predators, while John studied grazers. Answer the following question: Which student didn't study species that play an important role in an ecosystem????
output answer: John

input question: Given the background: When humans dig up and use fossil fuels, we have an impact on the carbon cycle ( Figure below ). This carbon is not recycled until it is used by humans. The burning of fossil fuels releases more carbon dioxide into the atmosphere than is used by photosynthesis. So, there is more carbon dioxide entering the atmosphere than is coming out of it. Carbon dioxide is known as a greenhouse gas , since it lets in light energy but does not let heat escape, much like the panes of a greenhouse. The increase of greenhouse gasses in the atmosphere is contributing to a global rise in Earth's temperature, known as global warming or global climate change. and the situation: Two neighboring countries France and Spain were competing for economical supremacy in Europe. Spain dug up fossil fuels and used it as an energy source. France used alternative sources of energy. Answer the following question: Which country contributed less to air pollution????
output answer:
France
