Final answer:
From 2010 to 2019, the observed trends are fluctuations in U.S. percent change at an annual rate, an increase in global life expectancies, and a rise in global protest movements. There's also an exponential growth in energy usage and U.S. Nominal GDP, whereas the U.S. unemployment rate does not show a stable long-term trend.
Step-by-step explanation:
The trend observed from 2010 to 2019 across all three metrics—U.S. percent change at an annual rate, global life expectancies, and global protest movements—indicate significant changes in each area. Firstly, the U.S. percent change at an annual rate graph fluctuates across the zero line, with low points during economic recessions like 2008 and a downward trend in 2020. Secondly, a study on global life expectancies would typically show an upward trend over the years as healthcare and living conditions improve worldwide. Lastly, there was a noted increase in global protest movements during the same period, indicating a rise in political and social activism.
Regarding energy use, the data implies an exponential growth trend in energy consumption, outpacing population growth, thus indicating an increase in per-capita energy usage. When examining the U.S. unemployment rate and U.S. Nominal GDP over the long term, we see that the unemployment rate has fluctuations but does not display a clear long-term upward or downward trend, while Nominal GDP has risen exponentially from 1960 through 2010.
