Three$-$Value Truth Tables$(2$ points per truth table$)$

We will now develop truth tables for this new scenario. To take the place of missing data we will use the truth value UNKNOWN $($U$).$ Think about how normal two$-$value truth tables work and if necessary create your own examples, perhaps using the table$($s$)$ above. You can run imaginary queries on the tables above using disjunction and conjunctions, eliminating various pieces of data from the tables and decide what the proper output should be$.$ Use this information and fill in the remainder of the truth tables below.
