What is the CRAAP test and how can you use it to evaluate information?
CRAAP is an acronym for Currency, Relevancy, Authority, Accuracy and Purpose. This can be applied during the research process to evaluate sources. Currency - How current is the information? When was it published, has it been updated, do the links work? Relevancy - Does this information match my needs? Who is this information for? What level is it written at? Would I be comfortable using this in academic or professional work? Authority - Where does this information come from? Who wrote it and published it? Is the author qualified? What organizations is the author or publisher affiliated with? Accuracy - Is this information true? Can you verify this information from other sources? Are there typos or other errors in the text? Has this information been reviewed? Purpose - Why was this published? Does the author have an agenda? Is this information fact or opinion? Is the author biased?

Why were the ancient Spartans afraid of the slave class (helots)?
Helots, the slave class in Sparta was formed out of conquered peoples. Helots in Sparta performed the bulk of agricultural labor and in emergency situations served in battle. Sparta relied on their slaves more than any other Greek city-state, and the Helots numbered seven times greater than the Spartans. Helots were also culturally and ethnically homogenous, and had a different religion than the Spartans. Spartans were constantly afraid of a slave rebellion for these reasons, and in 464 B.C.E there was a 5 year slave revolt.
