The answer #3 has a typo:
'2ndArgument' is not a valid identifier name because an identified must not start with a digit (although it can contain a digit.)'

should be:
'2ndArgument' is not a valid identifier name because an identifier must not start with a digit (although it can contain a digit.)'
