Problem: Many compound materials exhibit polymorphism, that is they can exist in different structures called polymorphs. Silicon carbide (SiC) is unique in this regard as more than 250 polymorphs of silicon carbide had been identified by 2006, with some of them having a lattice constant as long as 301.5 nm, about one thousand times the usual SiC lattice spacings.

Based on the paragraph above can we conclude that "Many cool compound materials exhibit polymorphism"?

A:
It's impossible to say
