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 need to come up with a question about the story that requires an understanding of the relationship described in the background paragraph. The generated question should not be answerable without both the background and story. Write a question about the story that requires a relationship in the background paragraph to answer. Check whether your question requires both the background paragraph and the story to answer. If your question can be answered by only one of these, try to rewrite your question so that it requires both. Note that "flipping" a word in the question can give rise to a new question where the answer will be different from the original question. Often, "flipping" a word gives rise to flipping the direction of the relationship, for example, from "increase" to "decrease."

Example Input: Background Paragraph: The primary advantage held by a player in late position is that he will have more information with which to make better decisions than players in early position, who will have to act first, without the benefit of this extra information. This advantage has led to many players in heads-up play raising on the button with an extremely wide range of hands because of this positional advantage.[3] Also, as earlier opponents fold, the probability of a hand being the best goes up as the number of opponents goes down. 
Story: Bill is in a poker tournament this week, and is very much wants to win. He has been placed randomly in certain positions for each day he is playing. On Monday and Tuesday he will be in an early position at the table. On Thursday and Friday he has been placed in a late position.
Example Output: Does Bill have a better or worse advantage on Friday than Monday?

Example Input: Background Paragraph: Increases in erosion due to farming and other operations will be reflected by changes in sediment composition and increases in deposition rates elsewhere. In land areas with a depositional regime, engineered structures will tend to be buried and preserved, along with litter and debris. Litter and debris thrown from boats or carried by rivers and creeks will accumulate in the marine environment, particularly in coastal areas. Such manmade artifacts preserved in stratigraphy are known as "technofossils."Changes in biodiversity will also be reflected in the fossil record, as will species introductions. An example cited is the domestic chicken, originally the red junglefowl Gallus gallus, native to south-east Asia but has since become the world's most common bird through human breeding and consumption, with over 60 billion consumed a year and whose bones would become fossilized in landfill sites. Hence, landfills are important resources to find "technofossils". 
Story: Mike is an an archeologist. He was pondering about how human legacy would be viewed in the future. For that, he was very interested in technofossils. He located a site with ample evidence of technofossils. He noted that site as site A. To compare site A with a site with no technofossils he located another site. He noted that site as site B.
Example Output: Which site would reflect less erosion due to human activities, site A or site B?

Example Input: Background Paragraph: Soil formation, or pedogenesis, is the combined effect of physical, chemical, biological and anthropogenic processes working on soil parent material. Soil is said to be formed when organic matter has accumulated and colloids are washed downward, leaving deposits of clay, humus, iron oxide, carbonate, and gypsum, producing a distinct layer called the B horizon. This is a somewhat arbitrary definition as mixtures of sand, silt, clay and humus will support biological and agricultural activity before that time. These constituents are moved from one level to another by water and animal activity. As a result, layers (horizons) form in the soil profile. The alteration and movement of materials within a soil causes the formation of distinctive soil horizons. However, more recent definitions of soil embrace soils without any organic matter, such as those regoliths that formed on Mars and analogous conditions in planet Earth deserts.An example of the development of a soil would begin with the weathering of lava flow bedrock, which would produce the purely mineral-based parent material from which the soil texture forms. Soil development would proceed most rapidly from bare rock of recent flows in a warm climate, under heavy and frequent rainfall. Under such conditions, plants (in a first stage nitrogen-fixing lichens and cyanobacteria then epilithic higher plants) become established very quickly on basaltic lava, even though there is very little organic material. The plants are supported by the porous rock as it is filled with nutrient-bearing water that carries minerals dissolved from the rocks. Crevasses and pockets, local topography of the rocks, would hold fine materials and harbour plant roots. The developing plant roots are associated with mineral-weathering mycorrhizal fungi that assist in breaking up the porous lava, and by these means organic matter and a finer mineral soil accumulate with time. Such initial stages of soil development have been described on volcanoes, inselbergs, and glacial moraines. 
Story: Ben and Jerry studied agricultural sciences. Ben was specialized in pedology and pedogenesis, while Jerry specialized in entomology and phytopathology.
Example Output:
Which person learned less about deposits of clay?
