Argh.  My apologies for spreading borked data.  I spliced query with
output data since usually I work without X windows on my computer and
there is no "copy-paste" functionality in bare console.  So I redirected
output from Prolog to file and supplied the query by hand and with error. 
Sorry!

As for you other question: yes, it appears to be a green cut.  I had to
familiarize myself with the terminology though and having just relearned
it my answer is a bit unsure.
