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.

Question: Where was the system similar to London Underground used as well?
Ans: Milan

Trying to avoid the scenes that marred the relay in the UK, France and the US, the city government designed a complex security operative to protect the torch relay, involving 1200 police officers and 3000 other people, including public employees and volunteers. Overall, the protests were peaceful in nature, although there were a few incidents such as the throwing of several water balloons in an attempt to extinguish the Olympic flame, and minor scuffles between Olympic protesters and supporters from Chinese immigrant communities.

Article: The islands enjoy a mild climate and varied soils, giving rise to a diverse pattern of vegetation. Animal and plant life is similar to that of the northwestern European continent. There are however, fewer numbers of species, with Ireland having even less. All native flora and fauna in Ireland is made up of species that migrated from elsewhere in Europe, and Great Britain in particular. The only window when this could have occurred was between the end of the last Ice Age (about 12,000 years ago) and when the land bridge connecting the two islands was flooded by sea (about 8,000 years ago).

Question: In Ireland where does the native animal and plant species mostly come from?
Ans:
Europe, and Great Britain
