Using the println statement, print out the value of the language element from the result tuple.

Michael, first you have a syntax error. Println must be followed by an opening and closing parentheses. 

println()

Also, you should use the result variable to access the language instead of using the greeting function again.

println( result.language)

Note: The instructions said 'element' so you could also use "println(result.1)". The task succeeded and the readability seems easier for me. But I think Amit said using .0 or .1 might not be best practice. Something about possible mix matches. Maybe someone could chime in. Thanks
