Final answer:
The governor's action to blockade the roads to Mount St. Helens was supported for public safety during the reawakening of the volcano in 1980.
Step-by-step explanation:
The governor's action was supported.
During the reawakening of Mount St. Helens in 1980, the governor of Washington ordered blockades placed across the roads to Mount St. Helens to keep people away. These blockades were a precautionary measure to protect the safety of the public. The closure of the area was supported by warnings issued by geologists and geophysicists about the potential hazards, including landslides and large-scale snow avalanches.
Despite being unpopular among some citizens who wanted access to their property and recreation sites, the closure was necessary for public safety and helped to prevent a higher number of fatalities during the subsequent eruption.
