What are the answer choices?
The second alternative is correct.
In a market economy, where there is free entry and exit of firms, price is determined by the supply and demand of goods and services. In this case, the government does not act directly as a market player, but as a regulator, which must maintain the proper environment for companies to develop and compete the market through competition, ie price. Thus, consumers benefit. The government takes some economic decisions to favor the economic environment, for example to ensure that there is no agreement, but production decisions are only up to the companies, without intervention.
Answer:
Correct answer is European diseases had killed much of the native workforce.
Explanation:
As we all know around 90 percent of Natives died because of the diseases and other problems that were brought to them by Europeans. That is why they could only turn themselves to slave trade. Slaves were usually imported from Africa.
Other answers are false, especially options one and three, which have no connection with historical events. When it comes to option 4 it was actually pretty often that Africans would sell slaves to Europeans.
It is false that the average person usually has between 15 - 30 acquaintances. An acquaintance is a person you know, so I'm sure you know more than 30 people. As you grow older, you meet more and more people, and the number is sure to surpass 30.
