Answer 6

I am pretty sure it is b because c is: The process of extracting a metal from its oxide is known as 'smelting'. Most smelting processes involve direct reduction of the ore by carbon to metal and carbon dioxide. The production of primary aluminium is a good example of such a process.

Answer 7

ok thanks turtle

Answer 8

In my opinion its not C or D. I would say A since mining techniques really wont changing anything. What is the definition of "mining techniques" in my opinion its miners having new skills on how to dig not new technologies such as dynamite or pick-ax. But A sounds more logical for modeling since the tried improving the tools. Look at it as a car back in the days the cars were all old and nasty compared to the cars that we have now but in those days it worked great and it was a great tool for transportation, but how did we make it to great cars now? from new models.

Answer 9

they had new mining techniques so they could dig deeper and find better minerals
