Scientists have been classifying living organisms for centuries. In the 1970s, organisms were classified in a five-kingdom classification scheme. However, two decades later, organisms called Archaebacteria were discovered. This led to a three-domain system of classification that combined some of the previous five-kingdom schemes. What does this change in classification methods demonstrate?

A.
Scientific theories can change as new evidence arises, but previous information is still useful.
B.
In order for new evidence to become laws, old theories must be discarded.
C.
In order for new evidence to become theory, it must prove that all other theories are wrong.
D.
Scientific theories that were proven at one time are no longer useful when new evidence arises.

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.  

the committees of correspondence were the american colonies’ means for maintaining communication lines in the years before the revolutionary war. in 1764, boston formed the earliest committee of correspondence to encourage opposition to britain’s stiffening of customs enforcement and prohibition of american paper money. the following year, new york formed a similar committee to keep the other colonies notified of its actions in resisting the stamp act. in 1773, the virginia house of burgesses proposed that each colonial legislature appoint a committee for intercolonial correspondence. the exchanges that followed built solidarity during the turbulent times and bring about the formation of the first continental congress in 1774.
