If there was only one political party, why were there four candidates for president in 1824?

Ok, call me out if I'm wrong, but the answer is because two candidates ran for the same party.

Explanation:

The candidates for the 1824 presidential election were John Quincy Adams, Andrew Jackson, William Crawford, and Henry Clay.  John Quincy Adams was the winner of the election and a Democrat, and so was Andrew Jackson, so two people of the Democrat Party ran for president at the same time.

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.
