The main reason why we cannot drill a hole to the Core is

See the explanation

Explanation:

At the inner core, you'd have to drill through solid iron. This would be especially difficult because there's near-zero gravity at the core and there it is super heat ness leverl that no-human can survive the heat of that core and many research are still under-work.

without the article i believe the answer could be a because algeria is a low soci-economic country in africa and most countries that ahve such qualities lack womens rights

since there isn't any suggested answers i will give you the reason and hopefully you can figure it

south africa, or rather all of africa, has not been in the location in which it is nowadays throughout the geological past. after the super-continent pangaea started to break apart, gondwanaland, in which was africa, moved further south, and parts of it came to be very close to the south pole. because the climate in this part of the world is very cold due to the very dispersed sun rays in there, what is now south africa, started to freeze, and the conditions were right for the formation of glaciers. the glaciers existed up until the period when gondwanaland started to break apart and what is now africa started to move towards north, sp it warmed up and the glaciers melted.
