What led to the fomentation of labor unions during the second industrial revolution?

Unprecedented immigration of people from Europe during the late 1800s increased the pool of people asking for jobs despite of  terrible  labor conditions. Since Civil Wars, no federal intervention over people rights, safety regulations, working hours or minimum wages were improved over the States. Meanwhile, throughout Europe, in lot of countries were appearing various forms of socialism, and that ideas came with inmigrants, even though they weren’t unsatisfied with their jobs, but they just wanted better conditions of laboring, less arbitrarily and most security.

when studying cause and effect, historians usually group the causes into different categories. for example, cultural causes reflect how a society’s literature and art convey the way the society saw itself in relation to the rest of the world. another resource that historians use to understand society is pop culture, which tells them the trends and ideas that are preferred by the common people. when studying cause and effect, it’s important to remember multiple causation, or the idea that an effect could have several causes and vice versa.  

the correct option is “cultural causes” since art and literature are related to the culture of a place. culture is determined by literature, art, music.

the correct option is “pop culture” since it reflects the likes and ideas of common people whereas the rest of the options do not focus on common people.  

the correct option is “multiple causation” since it refers to the idea that events are caused by multiple reasons, not just a single one.
