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: The first direct observational hint that the universe has a finite age came from the observations of 'recession velocities', mostly by Vesto Slipher, combined with distances to the 'nebulae' (galaxies) by Edwin Hubble in a  work published in 1929. Earlier in the 20th century, Hubble and others resolved individual stars within certain nebulae, thus determining that they were galaxies, similar to, but external to, our Milky Way Galaxy. In addition, these galaxies were very large and very far away. Spectra taken of these distant galaxies showed a red shift in their spectral lines presumably caused by the Doppler effect, thus indicating that these galaxies were moving away from the Earth. In addition, the farther away these galaxies seemed to be (the dimmer they appeared to us) the greater was their redshift, and thus the faster they seemed to be moving away. This was the first direct evidence that the universe is not static but expanding. The first estimate of the age of the universe came from the calculation of when all of the objects must have started speeding out from the same point. Hubble's initial value for the universe's age was very low, as the galaxies were assumed to be much closer than later observations found them to be. 
Story: Bob is an astrophysicist. He was pondering about the beginning of our universe. He pinpointed the time when the universe just began to exist. He labeled it as point A. To compare it with present situation of the universe he labeled the present time as point B. 
Question: In point A were the galaxies closer or farther from each other than in point B?
[EX A]: closer.

[EX Q]: Background Paragraph: Allergy symptoms can range from mild to severe. Mild symptoms might include itchy eyes, sneezing, and a runny nose. Severe symptoms can cause difficulty breathing, which may be life threatening. Keep in mind that it is the immune system and not the allergen that causes the allergy symptoms. Allergy symptoms can be treated with medications such as antihistamines. Severe allergic reactions may require an injection of the hormone epinephrine. These treatments lessen or counter the immune system’s response. 
Story: Two groups of  students went to the forest to explore nature and learn botany. Group D had some people experiencing mild allergy symptoms, and group C had a few folks with severe allergy symptoms, so they had to call the ambulance asap. 
Question: Which group had fewer people that could be treated with antihistamines?
[EX A]: group C.

[EX Q]: 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. 
Question: What days does Bill have the best advantage based on his position?
[EX A]:
Thursday and Friday.
