Hi Martin!

As Nicholas mentioned, the question is asking you to show string interpolation using #{}. When returning a string on the last line, the value of variable a is substituted in the following example:

def meaningOfLife
    a = 42
    return "The Ultimate Answer to Life, The Universe and Everything is...#{a}!"

This will return:

The Ultimate Answer to Life, The Universe and Everything is..42!

You have to use interpolation in the string you return to get your variables to show. To do this, surround each of them with #{ }. For instance, the 'a' variable in the string would not be #{a}. Hope that helps.
