Using the respond_to? method, ask the string variable if it responds to the upcase method. Remember, the respond_to? method can take a string or a symbol as an argument.
string = String.new("a random string")

method on the string
variable, and pass it the upcase
method name as argument.
You can call methods on variables this way - variableName.methodName
.
