Explanation:

The Watergate scandal was a major political scandal that took place in the United States in the 1970s as a result of a theft of documents in the Watergate office complex in Washington DC, home of the National Committee of the United States Democratic Party, and the subsequent the Nixon administration's attempt to cover up those responsible. When the conspiracy was uncovered, the United States Congress initiated an investigation, but the resistance of Richard Nixon's government to collaborate in this led to an institutional crisis.

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.
