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.

[Q]: Background Paragraph: Artworks are sold at affordable prices [6] ranging from £5 to £1500. For many of the works, the price goes up as the edition sells out. The edition runs range from 30 to 10,000 editions. Each work comes with a digital certificate that is “signed, numbered and authenticated by the artist” [7][8] Once an edition is sold out, collectors can resell their works in the online marketplace. 
Story: A respected art store had limited edition artworks for sale last week. They all had 400 pieces at the beginning of the week. By the end of the week, they started to sell out. There were only 3 The Grand Odalisque, 25 The Swing, 70 The Liberty Leading The People, 150 The Birth Of Venus, 200 Napoleon Crossing The Alps, 250 Musicians, and 270 American Gothic left. 
Question: Which limited edition most likely had it's price increased: The Swing or The Grand Odalisque?
[A]: The Grand Odalisque.


[Q]: Background Paragraph: Cholesterol can't dissolve in the blood. It has to be transported to and from the cells by carriers called lipoproteins. Low-density lipoprotein, or LDL, is known as "bad" cholesterol. High-density lipoprotein (HDL) is known as good cholesterol. When too much LDL cholesterol circulates in the blood, it can slowly build up in the inner walls of the arteries that feed the heart and brain. Together with other substances, it can form plaque, and lead to atherosclerosis. If a clot forms and blocks a narrowed artery, a heart attack or stroke can result. Cholesterol comes from the food you eat as well as being made by the body. To lower bad cholesterol, a diet low in saturated fat and dietary cholesterol should be followed. Regular aerobic exercise also lowers LDL cholesterol and increases HDL cholesterol. 
Story: Mary and Ben went in for a blood test. Ben had high cholesterol, so the Doctor recommended him to lower it. Mary had normal cholesterol levels. 
Question: Which person was at lower risk of forming blood clots?
[A]: Mary.


[Q]: Background Paragraph: When a solid substance is involved in a chemical reaction, only the matter at the surface of the solid is exposed to other reactants. If a solid has more surface area, more of it is exposed and able to react. Therefore, increasing the surface area of solid reactants increases the reaction rate. Look at the hammer and nails pictured in the Figure below . Both are made of iron and will rust when the iron combines with oxygen in the air. However, the nails have a greater surface area, so they will rust faster. 
Story: Andy is participating in this years science fair. He is testing how fast metal takes to rust. He rakes 3 pieces of iron one is a cube, and the other is a sheet both weighing the same. It takes the cube almost a week to fully rust but the sheet only takes 2 days. The only difference between the two is that the sheet has more surface area. He tries this again with a cylinder so the surface area is larger than the cube but smaller than the sheet and it takes about 4 days to fully rust. 
Question: Will making the surface area of iron larger increase or decrease how fast it rusts?
[A]:
increase.
