In 46–54, refer to the Tarski world given in Figure 3.1.1, which
is printed again here for reference. The domains of all variables
consist of all the objects in the Tarski world. For each statement,
(a) indicate whether the statement is true or false and justify
your answer, (b) write the given statement using the formal
logical notation illustrated in Example 3.3.10, and (c) write the
negation of the given statement using the formal logical notation
of Example 3.3.10.
There is a triangle x such that for all squares y, x is above y.
