Most of the time, all the soldiers in the trenches had to eat was:

The bulk of their diet in the trenches was bully beef (caned corned beef), bread and biscuits. By the winter of 1916 flour was in such short supply that bread was being made with dried ground turnips.

Germany and Austria-Hungary – with food supplies hit by the Allied naval blockade – made immense efforts to keep their soldiers fed; even if this increased the hunger being felt by their citizens at home. But starvation eventually played a key role in the collapse of the latter’s army in 1918.

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.
