Technically the bareback question is incorrect. Riding bareback means you aren't using a saddle. Many people who ride bareback will still use a bridle, which is still part of the tack set. Riding without tack (a saddle and a bridle) is simply called riding tackless, not bareback.
Not a bad quiz, but I think your wording needs work on some of these questions.
The term "yearling" among horses, is not an animal the age of which is between one and two years. A "yearling" is a horse, that has seen its first (but not its second) January 1st. Technically, a foal born on December 31st is a "yearling" the very next day.
What I mean DKChappell is that a white horse is in fact a white horse, it has unpigmented skin and white hair with light eyes, what is commonly mistaken as a white horse is a grey horse, which has black skin with dark eyes, so yes in fact, a white horse is white and a grey horse is grey.
Correct. There are indeed true white horses that are albinos. They have red eyes. Very light grey horses are still grey horses, despite being white in color. They are distinguished from white horses due to their very dark grey skin. Often they are born darker and lighten as they get older.
You want "lead rope," but neither lead nor rope work as an answer. Most people who care for horses would call it a lead, not a lead rope. Most leads are not ropes at all.
