Challenge: Protruding load: divisible or indivisible?

Most learners hunt for one fixed number — '1 metre, right?' The CBR exam designer counts on that and places a second load beside it that looks exactly the same but has a different answer. Because the front does not start with a number, but with one question: can you make the load smaller? If not (indivisible), it gets room in front. If you can (divisible), it may protrude nothing in front.
