Input: Read this: The structures of most federal governments incorporate mechanisms to protect the rights of component states. One method, known as 'intrastate federalism', is to directly represent the governments of component states in federal political institutions. Where a federation has a bicameral legislature the upper house is often used to represent the component states while the lower house represents the people of the nation as a whole. A federal upper house may be based on a special scheme of apportionment, as is the case in the senates of the United States and Australia, where each state is represented by an equal number of senators irrespective of the size of its population.
Question: What is intrastate federalism?

Output: is to directly represent the governments of component states in federal political institutions

Input: Read this: In January 2015, a customer named Ricardo Brown received a bill from Comcast with his name changed to "Asshole Brown". Brown's wife, Lisa, believed a Comcast employee changed the name in response to the Browns' request to cancel their cable service, an incident in which she was refused a cancellation unless she paid a $60 fee and instead was routed to a retention specialist. Comcast refused to correct the name on their bill after bringing it to the attention of numerous customer service outlets for the company by explaining that Ricardo is the legal name of the customer, so the Browns turned to consumer advocate Christopher Elliott. Elliott posted the facts of the incident, along with a copy of the bill, on his blog. Shortly thereafter, Elliott contacted Comcast and Comcast offered the Browns an apology, a $60 refund, and a promise to track down and fire the responsible employee. The Browns instead requested a full refund for their negative experience and Comcast agreed to refund the family the last two years of service and provide the next two years of service at no charge. Comcast released a statement explaining: "We have spoken with our customer and apologized for this completely unacceptable and inappropriate name change. We have zero tolerance for this type of disrespectful behavior and are conducting a thorough investigation to determine what happened. We are working with our customer to make this right and will take appropriate steps to prevent this from happening again."
Question: How many years did it take Comcast to rectify the situation?

Output: unanswerable

Input: Read this: Over the course of the 20th century, the world's per-capita gross domestic product grew by a factor of five, much more than all earlier centuries combined (including the 19th with its Industrial Revolution). Many economists make the case that this understates the magnitude of growth, as many of the goods and services consumed at the end of the 20th century, such as improved medicine (causing world life expectancy to increase by more than two decades) and communications technologies, were not available at any price at its beginning. However, the gulf between the world's rich and poor grew wider, and the majority of the global population remained in the poor side of the divide.
Question: What has Modern medicine increased the average life expectancy by?

Output:
two decades
