There are several synonyms for true and false. These include yes and no, or right and wrong. Therefore, to make a variable called Alice true and a variable called Bob false, you can write this.
<code>Alice was right.
Bob was wrong.</code>

The only values in Ruby that are false are: <code>false</code> and <code>nil</code>. They have synonyms <code>FALSE</code> and <code>NIL</code>.
Line 2,254 ⟶ 2,258:
<code>false</code>, <code>nil</code> and <code>true</code> are singleton instances of classes <code>FalseClass</code>, <code>NilClass</code> and <code>TrueClass</code> respectively.
