Answer:
The rough terrain blocked its extension into eastern lands. The seas kept it from connecting with northern lands. The river systems blocked passage along the trade routes. The <u>mountains forced it to follow a central route.</u>
If you can pick more than one, almost all of these are true (A, D, E). The ones that ARE NOT true would probably be: (B) Congress did not embark on a $1.6 trillion dollar expansion of the military, AFAIK. Military spending definitely rose, but the national debt rose by roughly that much due to the deficits created by the new budgets as a result of everything else -- not just the military. (C) is definitely not true, either; Reagan cut taxes for the highest tax tiers while closing loopholes, exemptions, and raising taxes on the lower tiers. If you were middle to lower class in terms of economics, you were hit.
