What actions were the most successful? Which ones caused problems? This is for the labor union protests to get better working conditions and pay.

The correct answer to this open question is the following.

When talking about union strikes during the Gilded Age or the Progressive Era, many strikes ended up being battlefields where blood was spilled and the workers failed. However, some others provided positive results for the workforce.

For instance, in 1892 in Hersey, Pennsylvania, workers united and rebelled against Andrew Carnegie who was the owner of Carnegie Steel Company. These workers labored under harsh conditions and demanded better salaries. People were sent to break the strike and both sides fight each other. Police had to intervene and nothing good resulted from the rebellion.

Two years later, in 1894, the Pullman Railroad Company workers organized a strike to demand improvements in salary, working conditions, and the reduction of the hours at work. The pressure of the workers was so hight and they maintained unity to the degree they force a shut down of the railway system in the country. The federal government had to send soldiers to Chicago.

hello there!

the graphics that you have attached within the question, indicates that few people in bolivia work in industry according to its labor force.

however, the graphic that is on the right side of the picture shows the gdp sector in bolivia. this gross domestic product is a macroeconomic magnitude   that shows the monetary value of all finished goods and services within a country's borders in a specific time period. in this case, the graphic is showing the monetary value in each sector -agriculture, industry and services- of bolivia in 2012.

so, although the first graphic located at the left side indicates that not so many people work in industry, this is the second most important sector according to the gdp metrics because of the monetary value that impacts on its country. it does not need to be the most valuable one. if it makes an impact on the country's economy, it will be definitely crucial to it.
