Re: Though the majority of rules in sports are physically

Explanation
The word though always sets up a contrast, so you need something for the blank that means the opposite of “physically described in rulebooks.” Both tacit and implicit mean “implied, but not plainly expressed.” Unambiguous and blatant have the opposite charge.
Hence options tacit, implicit are correct!
