Question

which scenario is most like the reason why revolutions started in nineteenth-century europe?workers believe that unions have too much power.business owners feel that taxes are too high.middle-class people believe that they are too poor.citizens conclude that their elected leaders are too lazy.

Explanation:

Nineteenth-century European revolutions (like 1848 uprisings) were driven by middle-class frustration: they faced limited political power despite growing economic activity, and many struggled with poverty or lack of upward mobility alongside working-class unrest. Other options do not align: unions had little power then, business owners were not the core revolutionary group, and leader laziness was not a key trigger.

Answer:

Middle-class people believe that they are too poor.
