how can a bag of Mauna Loa Mountain Milk Chocolate Covered Macadamia Nuts relate to federalism or any of the principles of the United States?

It doesn't

Explanation:

sorry but whats the question?

the pronoun reference replaces a noun, but you have to make sure there's no room for confusion.

in the first sentence "her" could be referring to shely or to the sister. the answer there is "shelly called her sister and told her about the new baby."

in the second sentence "it" could be referring to the roof or the floor. the answer there is "since the roof leaks on the family room floor, we need to repair the roof."
