15,392 PointsHi Hunter, Are you still having trouble understanding the point of this question?
Hunter Initiative
27,251 PointsYeah because it's already outputting a string and additional nil

15,392 Pointsdef 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!
