Exercise 1.7.10: Determining whether a quantified logical statement is true, part 2. About A student club holds a meeting. The predicate M(x) denotes whether person x came to the meeting on time. The predicate 0(x) refers to whether person x is an officer of the club. The predicate D(x) indicates whether person x has paid his or her club dues. The domain is the set of all members of the club. The names of the members and their truth values for each of the predicates is given in the following table. Indicate whether each expression is true or false.

About
A student club holds a meeting. The predicate M(x) denotes whether person x came to the meeting on time. The predicate 0(x) refers
to whether person x is an officer of the club. The predicate D(x) indicates whether person x has paid his or her club dues. The domain is
the set of all members of the club. The names of the members and their truth values for each of the predicates is given in the following
table. Indicate whether each expression is true or false. If a universal statement is not true, give a counterexample. If an existential
statement is true, give an example.
