Which describes communism in russia from 1917 to 1939? a) forced business leaders to join in government-led corporatism b) tolerated limited freedom of speech as long as it supported socialism c) permitted competitive elections for local and regional assemblies d) introduced collectivization of agriculture to rationalize farming

I would say the answer is A because communism is when the government controls businesses, so it makes sense that business leaders would have been forced to work with the gov't. Hope this helps. :)

The constant presence of diseases or infectious agents within a given geographic area or population group. it may also refer to the usual prevalence of a given disease with such area or group. it includes holoendemic and hyperendemic diseases. a holoendemic disease is one for which a high prevalent level of infection begins early in life and affects most of the child population, leading to a state of equilibrium such that the adult population shows evidence of the disease much less commonly than do children (malaria in many communities is a holoendemic disease). a hyperendemic disease is one that is constantly present at a high incidence and/or prevalence rate and affects all groups equally. so probably family history.
