You are given a background paragraph that describes one or more causal or qualitative relationships such as a relationship in economics or a scientific law and a story that makes use of the concepts or the relationship described in the provided paragraph. You are also given a question about the story that requires an understanding of the relationship described in the background paragraph and the story. You need to come up with an answer to the given question; the answer will be a span from either the question or the story. In order to correctly answer the given question, you need to understand the relationship mentioned in the background paragraph and should be able to use it to understand that in the story. Your answer can not consist of any word that is not mentioned in any of these: the background paragraph, the story, or the question. You can directly copy and paste a span from the story or the question while answering the given question.

Background Paragraph: Located mostly in the Arctic north polar region in the middle of the Northern Hemisphere, the Arctic Ocean is almost completely surrounded by Eurasia and North America. It is partly covered by sea ice throughout the year and almost completely in winter. The Arctic Ocean's surface temperature and salinity vary seasonally as the ice cover melts and freezes; its salinity is the lowest on average of the five major oceans, due to low evaporation, heavy fresh water inflow from rivers and streams, and limited connection and outflow to surrounding oceanic waters with higher salinities. The summer shrinking of the ice has been quoted at 50%. The US National Snow and Ice Data Center (NSIDC) uses satellite data to provide a daily record of Arctic sea ice cover and the rate of melting compared to an average period and specific past years.
Story: The Madrigal Ocean and the Listy Ocean are two bodies of water currently under observation by scientists on a planet nearly identical to Earth. Although the studies have just started, the scientists have already discovered that the salinity of the Madrigal Ocean is much lower than that of the Listy Ocean. This isn't much information, but it's progress and the scientists are not going to stop their studies until they learn all that they can about these waters.
Question: Is the Madrigal Ocean probably connected to more or less rivers than the Listy Ocean?
more.

Background Paragraph: The particles of soup have greater average kinetic energy than the particles of water in the tub, explaining why the soup has a higher temperature. However, the mass of the water in the tub is much greater than the mass of the soup in the pot. This means that there are many more particles of water than soup. All those moving particles give the water in the tub greater total kinetic energy, even though their average kinetic energy is less. Therefore, the water in the tub has greater thermal energy than the soup.

Story: Alexander is conducting reactions in his college chemistry class. In his first reaction, reaction A, he uses a large amount of reactants. In his second reaction, reaction B, he uses a much smaller amount of reactants compared to reaction A. As the reactions are proceeding, he measures that reactants in reaction A have low average kinetic energy. At the same time, reactants in reaction B have high average kinetic energy.
Question: Reactants in which reaction have smaller total thermal energy?
reaction B.

Background Paragraph: The quantity of small plastic fragments floating in the north-east Pacific Ocean increased a hundredfold between 1972 and 2012.Marine pollution is a generic term for the harmful entry into the ocean of chemicals or particles. The main culprits are those using the rivers for disposing of their waste. The rivers then empty into the ocean, often also bringing chemicals used as fertilizers in agriculture. The excess of oxygen-depleting chemicals in the water leads to hypoxia and the creation of a dead zone.Marine debris, also known as marine litter, is human-created waste that has ended up floating in a lake, sea, ocean, or waterway. Oceanic debris tends to accumulate at the center of gyres and coastlines, frequently washing aground where it is known as beach litter.In addition, the Pacific Ocean has served as the crash site of satellites, including Mars 96, Fobos-Grunt, and Upper Atmosphere Research Satellite.
Story: Tim and Joe were two friends living near two different oceans. Tim lived on the Pacific coast while Joe lived on the Atlantic coast.
Question: Which friend sees more marine pollution?
Tim.
