Input: Article: The London Underground in England is one of the few networks that uses a four-rail system. The additional rail carries the electrical return that, on third rail and overhead networks, is provided by the running rails. On the London Underground, a top-contact third rail is beside the track, energized at +420v DC, and a top-contact fourth rail is located centrally between the running rails at −210v DC, which combine to provide a traction voltage of 630v DC. London Underground is now upgrading its fourth rail system to 750v DC with a positive conductor rail energised to +500v DC and a negative conductor rail energised to -250v DC. However, many older sections in tunnels are still energised to 630v DC. The same system was used for Milan's earliest underground line, Milan Metro's line 1, whose more recent lines use an overhead catenary or a third rail.

Now answer this question: What is the voltage of the return rail?

Output: −210v DC

Input: Article: In the James Bond series by Ian Fleming, James Bond, reads The Times. As described by Fleming in From Russia, with Love: "The Times was the only paper that Bond ever read."

Now answer this question: What is the name of the spy and hero in Ian Fleming's books?

Input: Article: There is no clear mechanism by which these local trade organisations became today's Masonic Lodges, but the earliest rituals and passwords known, from operative lodges around the turn of the 17th–18th centuries, show continuity with the rituals developed in the later 18th century by accepted or speculative Masons, as those members who did not practice the physical craft came to be known. The minutes of the Lodge of Edinburgh (Mary's Chapel) No. 1 in Scotland show a continuity from an operative lodge in 1598 to a modern speculative Lodge. It is reputed to be the oldest Masonic Lodge in the world.

Now answer this question: What is the oldest Masonic Lodge in the world?

Output:
the Lodge of Edinburgh (Mary's Chapel) No. 1
