Read this paragraph from the National Oceanic and Atmospheric Administration, a federal agency focused on the condition of our oceans and atmosphere. What logical conclusion can you draw from details in this passage?

A range of natural records shows that the last 10,000 years have been an unusually stable period in Earth's climate history. Modern human societies developed during this time. The agricultural, economic, and transportation systems we rely upon are vulnerable if the climate changes significantly.


Most of the periods of earth’s climate history have been more stable than the current period.


A significant climate change will have a negative effect on the systems humans rely on.


Records indicate that the current climate is going to be stable for another 10,000 years.


The development of human societies on Earth does not depend on stable climate.
