Compare the positions of the Fedrealists and Democratic-Republicans on the national bank.I don't understand what they're asking me exactly, what...

When this question says "positions" it means "opinions." 
So the question is asking you to compare how the Federalists and the
Democratic-Republicans felt about the creation of a national bank.  In general, the
Federalists were for the bank and the Democratic-Republicans were opposed to the
bank.

The federalists were the party of the rich (for the
most part) and they wanted to create a country in which manufacturing businesses could
do well.  They felt that one way to do this was to create a national bank that would be
able to loan money and keep the currency sound.

By
contrast, the D-Rs were the party of small farmers and artisans.  They did not want the
federal government doing much at all and they especially did not want it to help create
a manufacturing economy that would benefit the rich.
