In a world of bartering, naomi produces a lot of goods on her own. in a world with money, she can her dream of teaching?
a. exchange
b. specialize in
c. trade

I believe the answer is: B. Specialize in

In the world of bartering, you can only obtain a goods by exchanging it with other goods. Which mean that your option for occupation would be limited to a producer for a certain goods.

In a world with money, you don't have to do that. You can choose occupation that is not related to production (such as painters, singers, or Teachers) and in exchange for your work, you can obtain money to buy the goods that you need.

when studying cause and effect, historians usually group the causes into different categories. for example, cultural causes reflect how a society’s literature and art convey the way the society saw itself in relation to the rest of the world. another resource that historians use to understand society is pop culture, which tells them the trends and ideas that are preferred by the common people. when studying cause and effect, it’s important to remember multiple causation, or the idea that an effect could have several causes and vice versa.  

the correct option is “cultural causes” since art and literature are related to the culture of a place. culture is determined by literature, art, music.

the correct option is “pop culture” since it reflects the likes and ideas of common people whereas the rest of the options do not focus on common people.  

the correct option is “multiple causation” since it refers to the idea that events are caused by multiple reasons, not just a single one.
