Hi Hunter, Are you still having trouble understanding the point of this question?

Yeah because it's already outputting a string and additional nil

def greet return "hello" end # Will return 'hello' because you explicitly use the return keyword.

def acknowledge "hello" end # Ruby methods ALWAYS return the last line of the expression unless return comes before it.

def welcome puts "hello" end # This method is printing 'hello' then return 'nil'

Hope this will help!
