Problem: Given the question: Extract the answer to the question from the following context. Question: What was the fourth reason for failure Context: While some teams have enjoyed considerable on-field and even financial success, many teams in the history of the league have enjoyed little success either on or off of the field of play. There are a number of franchises which existed in the form of a number of largely-unrelated teams under numerous management groups until they folded (an example is the New York CityHawks whose owners transferred the team from New York to Hartford to become the New England Sea Wolves after two seasons, then after another two seasons were sold and became the Toronto Phantoms, who lasted another two seasons until folding). There are a number of reasons why these teams failed, including financially weak ownership groups, lack of deep financial support from some owners otherwise capable of providing it, lack of media exposure, and the host city's evident lack of interest in its team or the sport as a whole.

The answer is:
the host city's evident lack of interest in its team


Problem: Given the question: Extract the answer to the question from the following context. Question: What was the most money you would give to see the match in the former  Soviet Republic? Context: All England matches are broadcast with full commentary on BBC Radio 5 Live. From the 2008–09 season until the 2017–18 season, England's home and away qualifiers, and friendlies both home and away are broadcast live on ITV (often with the exception of STV, the ITV affiliate in central and northern Scotland). England's away qualifiers for the 2010 World Cup were shown on Setanta Sports until that company's collapse. As a result of Setanta Sports's demise, England's World Cup qualifier in Ukraine on 10 October 2009 was shown in the United Kingdom on a pay-per-view basis via the internet only. This one-off event was the first time an England game had been screened in such a way. The number of subscribers, paying between £4.99 and £11.99 each, was estimated at between 250,000 and 300,000 and the total number of viewers at around 500,000.

The answer is:
£11.99


Problem: Given the question: Extract the answer to the question from the following context. Question: the main part of the brain is Context: The brain is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals. Only a few invertebrates such as sponges, jellyfish, adult sea squirts and starfish do not have a brain; diffuse or localised nerve nets are present instead. The brain is located in the head, usually close to the primary sensory organs for such senses as vision, hearing, balance, taste, and smell. The brain is the most complex organ in a vertebrate's body. In a typical human, the cerebral cortex (the largest part) is estimated to contain 15–33 billion neurons, each connected by synapses to several thousand other neurons. These neurons communicate with one another by means of long protoplasmic fibers called axons, which carry trains of signal pulses called action potentials to distant parts of the brain or body targeting specific recipient cells.
