Most of them are relatively tiny, around 6-10 meters tall. The biggest is 30 m tall. Khufu's Pyramid a.k.a. the Great Pyramid of Giza is, by contrast, 139 m tall (and 147 m originally). The Egyptians were a far more accomplished, important, and influential civilization than the Nubians directly to the south, and thus more famous and well-known.

Schrödinger's cat implies that when the cat is in the box, it is impossible to tell if it is still alive, and you can only find out by opening the box.

After looking it up, I learned that there are species of bamboo native to essentially every tropical climate, ranging from Cuba, to Madagascar, to Chile, to Ghana. Hell, there are bamboo forests in France and New Jersey these days. Turns out you're totally right and I've come around. I think the clue could be better phrased. Simply "world's tallest grass variety" would probably do.
