Scientists have tools that monitor volcanic activity. However, there are too many volcanoes and not enough time or tools to monitor them all. What would be the best way to improve monitoring of volcanoes?
not monitor any volcanoes because it is too expensive
keep track of patterns of when volcanoes erupt, and only monitor the ones that may be close to erupting
monitor all the volcanoes, but don't interpret the data we get from the tools
because volcanic eruptions are not dangerous to people, we do not need to monitor them
