sent1: something is not a kind of an epic if that it is not aphanitic and it is tuberous is not correct. sent2: the fact that either the American is tuberous or it is a calculator or both is not right if that the gravity is not epic is true. sent3: the gravity is a Santalum. sent4: the American is an epic or a Santalum or both. sent5: the gravity is a kind of a Scolopacidae if it is a Santalum. sent6: the gravity is aphanitic if the ephemera is aphanitic. sent7: something is not a kind of an epic if that it is not a Scolopacidae is true.
