Explanation:

Feudalism with the Frankish conquests at the end of 8th and in the beginning of the 9th century was spreading to Italy, Spain, Germany, further towards to the east of Europe, primarily to Hungary and to some Slavic countries.

The Normans transferred it to the conquered lands - in 1066 to England, then to the south. Italy and Sicily. From England, feudalism spread to Ireland and Scotland.

English feudalism was organized purposefully from above, by a king who attempted to regulate the administrative structure in this way. Therefore, they developed a practice in which the vassals were rewarded with counties for vassalage, and in turn they subjected themselves to the warriors they had to feed.

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.
