Выражение не имеет смысла при значении переменной 1, потому что получется
, а ноль ни на что не делится.Так же возможен второй вариант, при переменной равной -4Тогда получится

Mount St Helens, the volcano in Clark County , Washington State , erupted on Monday morning . The disaster has caused at least ten deaths as well as massive destruction in that region of the state. The mountain was hit by two earthquakes just before half past eight. Then , at eight thirty two , the top of the mountain was blown off by an explosion that was heard two hundred miles away. Huge blocks of ice and rock fell onto the surrounding area end the mountain was left 1,300 feet shorter . Then the tremendous heat inside was released . Hot ash and gas come out of the mountain , causing a lightning storm as it rose into the air . White ash , along with steam and thick mud , continue to pour from the giant crater left by the explosion. At each state of this dramatic eruption people have been killed . The explosion caused the first casualties ; several people were injured or died due to the force and heat of it. Then the hot ash started fires which have burned vast areas of forest , causing more deaths . Fortunately , fire fighters have managed to put most of them out . The volcanic cloud was so large and dark that it was said to have turned day into night , forcing airports to close temporarily . One more life was lost as a pilot flew his aeroplane into the cloud and hit electricity cables . mud from the volcano is running down the mountainside and filling rivers , causing flooding . People living nearby have been forced to leave their homes as the water continues to rise . Rescue workers have picked up casualties and survivors by helicopter , and are moving them away from the dangerous areas . More victims are expected to be found during the next few days . one witness said that it had been like the end of the world . “I really thought we were all going to die , “ jerry Irvine said . “ I’ve never been so terrified in my life .” Scientists say that the top of the mountain had been ‘growing’ by five feet per day for several weeks before the explosion . they say that ash and mud cloud continue to pour out of St. Helens for up to fifteen years. Meanwhile , the people of Clark County are learning to cope with nature’s fury-
