A better point of comparison would not be a question like "what is 2+2," but "what is 4?" There's a superficial, circular answer ("What is 4? It's 2+2"), and there's a more complex and rigorous answer which doesn't look good on camera ("What is 4? Well, numbers are a social construct used to communicate and analyze etc etc, Peano arithmetic blah blah").

These questions also admit "straightforward" answers ("what's 4?" raises 4 fingers "this many") ("what's a woman?" points to a woman "one of those"), but these don't really answer the deeper question being asked. They gesture at a preexisting category and demand that it be recognized without actually explaining the nature of that category or its boundaries.
