 GEOG: A voiceover from a news broadcast tells of the city of Rome  being threatened by eruptions of Mount Vesuvius and Mount Etna.  Vesuvius is in the vicinity of Naples, over 100 miles from Rome;  Etna is on the island of Sicily, over 200 miles from Rome and  separated from the Italian mainland by the Straits of Messina.  Neither mountain is in a position to threaten Rome, even in the case  of a severe eruption. The only possible reason for mentioning them  is 1: theyre volcanoes and 2: theyre in Italy.
