Answer 2

Ok I do understand your confusion about "four score and seven years ago". Most people don't know how long a score is any more since it was a more common way of calculating years back in Abe Lincoln's day. 87.

But have you tried to answer some of these other questions on your own yet. It is ok to ask for help when you are stuck on a question like with score. You are intelligent. You have a computer and the internet. Try looking up some of the answers for yourself. Please use your brain cells.
