6.3ex IV

In each form field, just enter any substitution instance of the sentence which originally occurs there.

To do this, simply remove the quantifier which is the main connective (it's always on the far left) and replace every occurrence of that quantifier's variable with any name (you pick one). That's it!

Rewrite each of the following sentences. Take the quantified sentence and replace it with a substitution instance. (Remember: A substituion instance removes one quantifier and replaces all remaining instances of its variable with instances of one name.)
