Detailed Instructions: In this task, you're given a question, a context passage, and four options which are terms from the passage. After reading a passage, you will get a brief understanding of the terms. Your job is to determine by searching and reading further information of which term you can answer the question. Indicate your choice as 'a', 'b', 'c', or 'd'. If you think more than one option is plausible, choose the more probable option to help you answer the question.
Q: Question: What makes up a majority of the stuff in landfills other than plastic and paper? Passage:He started by surveying different areas of the country to better understand what types of garbage survives under different climates. He found there was little difference between the sites because the garbage is compacted. The California landfills did have less paper than those in Illinois. Recycling is thought to be the cause of the paper difference between states. Rathje's research uncovered some other misconceptions about landfills. In particular, it was revealed that the rate of natural biodegradation is far slower than had been assumed (e.g., in capacity planning). It was found that the plastic bottles that were crushed at the top were able to be re-inflated easier than those that were at the bottom because of a new system of bottle making called light-weighting. This is the process of using less plastic in bottles to conserve material and save money. Light-weighting is not limited to plastic alone; this process is used for aluminum and paper as well. Rathje also found that Americans were wrong about what they thought they threw away most. When combined, the three most infamous types of trashdiapers, fast food containers, and Styrofoamamounted to less than three percent of the landfill's waste. Rathje found that plastic was 20-24 percent of waste and paper alone was 40 percent of the waste found in landfills. Thirteen percent of this paper waste was from newspapers. Rathje states the irony of this fact in his book. He talks about how newspapers are usually the ones that report things such as waste and pollution and it is these same newspapers clogging the landfills. Rathje discusses the rate of closing landfills and how for every six small landfills closed one large landfill opens. At the time he published his book he predicted that in the next five years 50 percent of the landfills open at the time would close. He determined this from his findings. In an effort for states to prevent their area becoming a large landfill often states ship their trash to other states. States such as Michigan are taking measures to prevent their state from being the landing spot for the nation's trash. Michigan has found that in the past years most of their rise in trash rates are because of trash imports from Canada.
