It is stated in the passage that the Arctic ............. .

A vital zone between North America's and
Russia's northernmost frontiers consists of
the Arctic regions. Once only explorers,
traders and Eskimo hunters were interested
in the vast, icy area at the "top" of the
world. Today, because of its strategic
location and its value to scientists, the
Arctic is the scene of much activity. The
Arctic is studded with air bases, constant
reminders that the shortest air routes
between the United States and Russia are
over the area. Only a narrow channel
separates Little Diomede Island, of the
United States, from Big Diomede Island,
which is Russian territory. The long-range
missile and the nuclear-powered submarine
have made distances between the two
countries seem even shorter. Year-round
scientific research stations are maintained to
study weather, climate and mineral
resources of the Arctic.
