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.

[EX Q]: Background Paragraph: Noble gases are also used to fill the glass tubes of lighted signs like the one in the Figure below . Although noble gases are chemically nonreactive, their electrons can be energized by sending an electric current through them. When this happens, the electrons jump to a higher energy level. When the electrons return to their original energy level, they give off energy as light. Different noble gases give off light of different colors. Neon gives off reddish-orange light, like the word “Open” in the sign below. Krypton gives off violet light and xenon gives off blue light. 
Story: Bob owns a store that sells signs. He has a large selection of different signs that are for sale, and they come in all sorts of different colors. His closed sign is a reddish-orange. His open sign is a violet color, and his sale sign is blue. 
Question: Is the closed sign more or less likely to be Krypton than Neon?
[EX A]: less.

[EX Q]: Background Paragraph: Storing large volumes of data – When storing XML to either file or database, the volume of data a system produces can often exceed reasonable limits, with a number of detriments: the access times go up as more data is read, CPU load goes up as XML data takes more power to process, and storage costs go up. By storing XML data in Fast Infoset format, data volume may be reduced by as much as 80 percent. 
Story: Bob works for a data storage company. He has now three projects, project A, project B, and project C, simultaneously going on. All of them involves storing 
XML data. Project A has small volume of data, but project B and project C has large volume of data. He applied Fast Infoset format for project B, but didn't apply that format for project C. 
Question: Would project A have higher or lower access times compared to project C?
[EX A]: lower access times.

[EX Q]: Background Paragraph: According to current definitions, all planets must revolve around stars; thus, any potential "rogue planets" are excluded. In the Solar System, all the planets orbit the Sun in the same direction as the Sun rotates (counter-clockwise as seen from above the Sun's north pole). At least one extrasolar planet, WASP-17b, has been found to orbit in the opposite direction to its star's rotation. The period of one revolution of a planet's orbit is known as its sidereal period or year. A planet's year depends on its distance from its star; the farther a planet is from its star, not only the longer the distance it must travel, but also the slower its speed, because it is less affected by its star's gravity. No planet's orbit is perfectly circular, and hence the distance of each varies over the course of its year. The closest approach to its star is called its periastron (perihelion in the Solar System), whereas its farthest separation from the star is called its apastron (aphelion). As a planet approaches periastron, its speed increases as it trades gravitational potential energy for kinetic energy, just as a falling object on Earth accelerates as it falls; as the planet reaches apastron, its speed decreases, just as an object thrown upwards on Earth slows down as it reaches the apex of its trajectory.Each planet's orbit is delineated by a set of elements:. 
Story: John is an amateur astronomer. Last week he was observing the sky with his telescope. First he pointed his telescope at planet Mars. He noted it as case A. Then he pointed his telescope to planet Jupiter, which is farther form the Sun than Mars is. He noted it as case C. Finally, he pointed the telescope to a faraway planet called WASP-17b. He noted that as case B. 
Question: Would case C have longer or shorter year than case A?
[EX A]:
longer.
