What change in government policy took place at the end of world war i? a) the federal bureaucracy was desegregated. b) the size of the military was drastically reduced. c) income taxes were increased to pay off the war debt. d) unions were given the right of collective bargaining.

The right answer is B. It is not uncommon that after a major conflict a country downsizes its military force. This occurred, for instance, in the United States, and this was seen as an opportunity to reform the Army. England, where the military consisted in part of volunteers, also rushed to demobilize its force. Germany, on the contrary, was forced to drastically reduce the size of its military force as a result of the signing of the Versailles Treaty (1919).  

c.) biotic: snails; abiotic: temperature climate

i would say it is a and b.

hope this
