there is something such that if it is not proximal then that it does care and/or it is not a kind of a diagonal does not hold.
sent1: the fact that the fact that the lutetium does care and/or it is not the diagonal does not hold if the lutetium is not proximal is not incorrect. sent2: there is something such that if the fact that it does not snag pinch is true then it is a kind of a toolbox. sent3: that something is mesic and/or does not rice Salvelinus does not hold if it is not a diagonal. sent4: the ponce is not a kind of a passage if it does not rice Salvelinus.
sent1 -> hypothesis;
if the pinch is not a diagonal then the fact that either it is not non-mesic or it does not rice Salvelinus or both is not right.
