Let’s say the average gdp per capita for the world’s countries is $10,500. the gdp per capita of country a is $8,000. most of the workforce is employed in either primary or secondary sector jobs. what is most likely about country a’s economic development? a. country a has a developed economy. b. country a has a developing economy. c. country a has a least-developed economy. d. we can tell nothing about the economic development of country a.

That wouldn't really be possible, the world could never really stand on it's own two economic feet, with this very small amount. The world's leaders, would crumble. (not all, and this is an understatement )
Besides, I don't understand the question being asked, If I were to make an Educated guess, I would have to choose C, based off of the only info I get from the question asked.
Im probably wrong, but I just want to answer considering no one else has answered yet.
