<h2>TrueFalse</h2>
<p>Boolean data is one bit of information. True or false.
It is common to use Booleans with control statements to
determine the flow of a program. In this example, when the
boolean value "x" is true, vertical black lines are drawn and when
the boolean value "x" is false, horizontal gray lines are drawn.</p>
