What do the quotations below illustrate about the shift in the role of the federal government during this period?

Incomplete question, however I infer you want to know more about the role of the federal government.

Explanation:

Remember, the federal government has certain privileges which the other tiers of government (state, local)  do not have, such as;

1. It alone can decide policy on foreign trade.

2. it can decide on taxes.

3. It alone can decide to go to war with another nation.

4. It can make policy on government spending etc.
