Question: The final has never been contested by two teams from outside the top division and there have only been eight winners who weren't in the top flight: Notts County (1894); Tottenham Hotspur (1901); Wolverhampton Wanderers (1908); Barnsley (1912); West Bromwich Albion (1931); Sunderland (1973), Southampton (1976) and West Ham United (1980). With the exception of Tottenham, these clubs were all playing in the second tier (the old Second Division) - Tottenham were playing in the Southern League and were only elected to the Football League in 1908, meaning they are the only non-league winners of the FA Cup. Other than Tottenham's victory, only 24 finalists have come from outside English football's top tier, with a record of 7 wins and 17 runners-up: and none at all from the third tier or lower, Southampton (1902) being the last finalist from outside the top two tiers.

Answer: Has the final been played by a two clubs outside of the top divisions?

Question: The Delhi Metro is a rapid transit system serving New Delhi, Delhi, Gurgaon, Faridabad, Noida, and Ghaziabad in the National Capital Region of India. Delhi Metro is the world's 12th largest metro system in terms of length. Delhi Metro was India's first modern public transportation system, which had revolutionised travel by providing a fast, reliable, safe, and comfortable means of transport. The network consists of six lines with a total length of 189.63 kilometres (117.83 miles) with 142 stations, of which 35 are underground, five are at-grade, and the remainder are elevated. All stations have escalators, elevators, and tactile tiles to guide the visually impaired from station entrances to trains. It has a combination of elevated, at-grade, and underground lines, and uses both broad gauge and standard gauge rolling stock. Four types of rolling stock are used: Mitsubishi-ROTEM Broad gauge, Bombardier MOVIA, Mitsubishi-ROTEM Standard gauge, and CAF Beasain Standard gauge.

Answer: What is the total length of the Delhi Metro?

Question: Synapses are the key functional elements of the brain. The essential function of the brain is cell-to-cell communication, and synapses are the points at which communication occurs. The human brain has been estimated to contain approximately 100 trillion synapses; even the brain of a fruit fly contains several million. The functions of these synapses are very diverse: some are excitatory (exciting the target cell); others are inhibitory; others work by activating second messenger systems that change the internal chemistry of their target cells in complex ways. A large number of synapses are dynamically modifiable; that is, they are capable of changing strength in a way that is controlled by the patterns of signals that pass through them. It is widely believed that activity-dependent modification of synapses is the brain's primary mechanism for learning and memory.

Answer:
How many synapses does the human brain supposedly contain?
