  <h2>Conditionals1</h2>
  
  <p>Conditions are like questions. 
  They allow a program to decide to take one action if 
  the answer to a question is true or to do another action
  if the answer to the question is false. 
  The questions asked within a program are always logical
  or relational statements. For example, if the variable 'i' is 
  equal to zero then draw a line.</p>
