there is something such that if it does not braid wood-frog and is not a sou then it is not nocturnal.
sent1: there exists something such that if it does not braid wood-frog and is not a sou it is nocturnal. sent2: if the gaur does not braid wood-frog and is not a sou then it is not nocturnal. sent3: there exists something such that if it does braid wood-frog and is not a sou it is not nocturnal. sent4: if something that does not braid Helleborus is not nocturnal then it is not high-interest. sent5: there exists something such that if it is both not mesic and a uplink then it is not Mesozoic. sent6: if the gaur is lung-like and not a FHLMC then it is not a sou. sent7: that the gaur is nocturnal is right if it does not braid wood-frog and it is not a kind of a sou. sent8: the gaur is non-nocturnal if it does not braid wood-frog and is a kind of a sou.
sent2 -> hypothesis;
the fact that the papillon is not high-interest is not wrong if it does not braid Helleborus and is not nocturnal.
