That's partly because Perl is the default value if you look at the source (use the source, Luke). If you get one of each of the 6 options (or 2 each of 3 options etc.) you still come out as being Perl. Also it looks like all the good answers end up as Perl. I suspect a certain amount of prejudice on the part of the quiz author, in fact reading the descriptions of java, vb and assembler I'm sure of it.
