from the text.

The first thanksgiving feast did last 3 days- that says something considering the fact we get only one day to celebrate good food and giving thanks

the answer is:

magna carta

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."
