Where do most of russia's rivers flow? north, into the arctic ocean west, into the black ocean, east, into the pacific ocean, south, into the caspian sea

The correct answer is 'North, into the Arctic Sea'. Even though Russia's most notable river, the Volga River, flows into the Caspian Sea, the majority of its longest rivers and basins run through the extensive siberian territory and into the Arctic sea, the country's northermost frontier. Among them we can count the Ob, Yenisei, Taz, Olenyok and Lena rivers.  

i really really really really really really dont know

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.
