An Equine Reproduction Adventure doesn't sound like an enjoyable subject for a text game, but I was surprised to find this is a medically instructional sort of interactive quiz that would help a veterinarian review procedure to diagnose a champion horse that's not breeding properly.
The interaction here is actually quite clever, hooking responses to directions, using the standard map of rooms and locations to make decisions. For example, the room description explains to go east to do a visual exam, or west to decide the problem is not with the mare. Five stars for thinking outside the box to make IF a viable medium for an educational simulation.
