How do think a countries literacy rate might affect its GDP

If a country has a low literacy rate it means education is worse (obviously), so worse the education means less educated people, which means less architects, to build good roads, buildings, ect. Also less scientist to increase crop efficiency, and of course less people educated in business so basically it effects the economy a lot when there is a low literacy rate.

And inversely if there is more educated people (higher literacy rate) there is more of all of the above.

d is the logical answer but im not a 100% sure

heat from the core of the earth causes convection currents to occur in the mantle. these currents slowly move the crust around.
