Green can communicate safety to proceed, as in traffic lights. Green and red were standardized as the colors of international railroad signals in the 19th century. The first traffic light, using green and red gas lamps, was erected in 1868 in front of the Houses of Parliament in London. It exploded the following year, injuring the policeman who operated it. In 1912, the first modern electric traffic lights were put up in Salt Lake City, Utah. Red was chosen largely because of its high visibility, and its association with danger, while green was chosen largely because it could not be mistaken for red. Today green lights universally signal that a system is turned on and working as it should. In many video games, green signifies both health and completed objectives, opposite red.

Bermuda's economy is based on offshore insurance and reinsurance, and tourism, the two largest economic sectors. Bermuda had one of the world's highest GDP per capita for most of the 20th century and several years beyond. Recently, its economic status has been affected by the global recession. It has a subtropical climate. Bermuda is the northernmost point of the Bermuda Triangle, a region of sea in which, according to legend, a number of aircraft and surface vessels have disappeared under supposedly unexplained or mysterious circumstances. The island is in the hurricane belt and prone to severe weather. However, it is somewhat protected from the full force of a hurricane by the coral reef that surrounds the island.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What is Bermuda's economy based on in addition to offshore tourism?
Ah, so..
