Hi all,
I used them when teaching IREX back in day as well. The old myth about the IREX was that it wasn't an aviation exam, its an 'english exam'. Not true! Every exam requires you to gather to all the facts and interprupt what is actually being asked so you give the correct answer.
This is where the examples are very handy to give the students the idea of how the questions were written, how to interprupt them and to really follow the good ol' RTFQ rule.
RTFQ being: Read...The ...
FULL...Question.
You can build scenarios around the questions and do alsorts of fun stuff with them in the classroom.
Also, towards the end of my instructing career, most of the students spoke english as a second language. The examples help with their comprehension of what was being asked.
And, as Bob said, all legal and above board.
Cheerio for now,
Mister W.
