Cactus Hill site has human remains that have been dated to around 20,000 years ago. Given its location in Virginia shows that human beings had reached America earlier than this. This contradicts the theory that postulates humans came to America from Siberia through the modern day Bring Strait. The theory asserts that at the end of the Ice age humans were able to cross to America through the Beringia land bridge and other means such as canoes and rafts around 10,000 years ago.

Archaeologists base their conclusions on artifacts found over a large area. Exact dates cannot always be determined, and scientists don't always agree on the data provided by the evidence. New findings may contradict theories that have already been accepted.

In a general election each state has officials who count and_______ Votes
coldgirl [10]

In the USA.gov, you can find the following description for an Election Official:

<em>"Election Official (also Poll Worker, Election Clerk, Election Judge) — A person appointed to monitor the voting process at a polling place, make sure voters follow state requirements, certify an election was conducted legally, and give the official vote count"</em>

So, by the phrase that we must complete, we know that counting is one of the things that the Election Official does, but according to the quotation, they are also the ones who certify that the election was conducted legally, meaning the word that fills in the blank correctly is Certify.

Compare and contrast middle ages and renaissance
Westkost [7]
The Middle Ages and Renaissance periods shared many similarities and many differences. The Middle Ages were considered dark and barbaric, while the Renaissance (meaning rebirth) was a vibrant and prosperous period. Both had social classes, but during the Renaissance these classes were more relaxed and less rigid. Literature and arts were very important during both time periods. Society became more educated during the Renaissance and citizens enjoyed a wider variety of writings. In the Middle Ages, typically only clergy and the upper classes could read. Religion was important during both periods. However, during the Middle Ages religion was never questioned and the Roman Catholic Church reigned supreme. The Renaissance would see the Church viewed with skepticism and doubt.
