A few mistakes in the quiz, like the one on "which antilope is born with horns"- common misconception that a gemsbok is born with horns, which of course is not true. Gemsbok cows do hide their calves for up to 4 weeks, in which time the horn rapidly grows to about 10 inches. When the casual observer spots such an calf for the first time, they think that it must have been born with the horns.
