The type of economy that is also known as capitalism would be a "market economy," and it would be "d. How should it be ensured that goods and services are paid for?," that is not a <span>key economic question, since the consumer "answers" this. </span>
There are many answers to this. One way they became the most recognized is because they first cocola was made by accident. The person who made it really didn't make it himself, his assistant did. Another way they became the most recognized product is because it was made to help headaches.
It was used as an engine in locomotive trains, & also in steam boats. it also helped create electricity which allowed things such as morse code & synchronization of the world’s clocks.
I haven't ever done that but I think it might be for Machine made I think it would be Harvesters and for Hand made I think it would be the first airplane I'm not sure what the first airplane is call tbh.
Sorry if I'm wrong... :(
