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.

Question: Background Paragraph: A baby is born with zones of cartilage in its bones that allow growth of the bones. These areas, called growth plates , allow the bones to grow longer as the child grows. By the time the child reaches an age of about 18 to 25 years, all of the cartilage in the growth plate has been replaced by bone. This stops the bone from growing any longer. Even though bones stop growing in length in early adulthood, they can continue to increase in thickness throughout life. This thickening occurs in response to strain from increased muscle activity and from weight-lifting exercises. 
Story: Two brothers, Tom, aged 26, and Paul, aged 16 were into sports. Tom started weight-lifting to gain more muscle mass. Three years later he was 20-25 lbs. heavier. Paul started track and field, he liked running. 
Question: Which brother had thicker bones after three years?

Answer: Tom.


Question: 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: Roger had a busy day storing XML. At 4 PM, he stored 22211 Gigabytes to the database. At 5 PM, he stored 33322 Gigabytes to the database. At 6 PM, he stored 44433 Gigabytes to the database. At 7 PM, he got dinner. At 8 PM, he stored 55544 Gigabytes to the database. At 9 PM, he stored 66655 Gigabytes to the database. At 10 PM, he went to sleep to finish storing XML tomorrow. 
Question: What time did access times go up: 4 PM or 10 PM?

Answer: 4 PM.


Question: Background Paragraph: Organisms can use different strategies to increase their reproduction rate. Altricial organisms are helpless at birth, and their parents give them a lot of care. This care is often seen in bird species. ( Figure below ). Altricial birds are usually born blind and without feathers. Compared to precocial organisms, altricial organisms have a longer period of development before they reach maturity. Precocial organisms, such as the geese shown below, can take care of themselves at birth and do not require help from their parents ( Figure below ). In order to reproduce as much as possible, altricial and precocial organisms must use very different strategies. 
Story: A female goose now has a large family of chicks, the chicks mostly fend for themselves and can move around almost immediately after being born. A short way away a female dog gives birth to a litter of puppies. These on the other hand are defenseless, cant really move and are blind. They require extensive care from their mother. 
Question: Given a new species of animal is discovered, this animal is very self sufficient at birth and can move and fend for itself, will this new species be altricial or precocial?

Answer:
precocial.
