The worksheet says:

Write the key policies of administration associated with the motto.

I already asked but, key policies means what general policies were used or Acts passed?

because for other motto's I couldn't find Acts passed.

I'm still confused for some reason!

I've looked at definitons for policy.

I need an example:
like for New Freedom
what would be the key policies?

This Wikipedia article answers your question.

http://en.wikipedia.org/wiki/The_New_Freedom

The New Freedom is the policy of U.S. President Woodrow Wilson which promoted antitrust modification, tariff revision, and reform in banking and currency matters.

Would this be the key policies?

Because for the Square Deal I was told that The Pure Food and Drug Act was a policy.

Right. The Square Deal included the Pure Food and Drug Act.

For the New Freedom, those would be the policies?

New Freedom policies: "antitrust modification, tariff revision, and reform in banking and currency matters"

Would it be necessary for me to write like Tariff Revision (Underwood Act)?

I don't think so. Check with your instructor.

ok thank you

You're welcome.
