  <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>
