Answer
a. $\forall x$, if x is a Java program, then x has at least 5 lines.
b. $\forall x$, if x is a valid argument with true premises, then x has a true conclusion.
Work Step by Step
Recall the form of the universal conditional statement:
$\forall x$, if $P(x)$, then $Q(x)$.
In (a), P(x) is: x is a Java program
Q(x) is: x has at least 5 lines
In (b), P(x) is: x is a valid argument with true premises
Q(x) is: x has a true conclusion.
