write the following sentences as quantified logical statements, using the universal and existential quantifiers, and defining predicates as needed.
Second, write the negations of each of these statements in the same way.
Finally, choose one of these statements to prove. If it is true, prove it, and if it is false, prove its negation. Your proof need not use symbols, but can be a simple explanation in plain English.

If the domain consists of all animals, express
the following statements in terms of quantifiers and logical
connectives, where B ( x ) = x is a bear,
G ( x ) = x raids garbage cans, H ( x ) =
x loves honey, and T ( x ) = lives in
tents.
A bear lives in a tent.
Bears love honey.
Only bears raid garbage cans.
No bear lives in a tent.
Some bears do not love honey.
