there exists something such that if it is not imperceptible that it does not peg Carboniferous and it is not nectariferous does not hold.
sent1: that that the radish pegs Carboniferous but it is not nectariferous is false is not incorrect if it is not imperceptible. sent2: the fact that if the radish is not imperceptible the fact that the radish does not peg Carboniferous and is not nectariferous is not true is correct. sent3: that something is not a Nevada and is not lobar is not true if it is not numerical. sent4: if the reverse does not peg Colubridae then the fact that it does not peg Carboniferous and it is atomistic is not true. sent5: that the radish does not peg Carboniferous and is nectariferous is not correct if it is not imperceptible. sent6: there exists something such that if it is not a swimmer then that it does peg Cortinarius and does not rummage gulch is wrong. sent7: there exists something such that if it is not imperceptible it does not peg Carboniferous and is not nectariferous. sent8: there is something such that if it is imperceptible then the fact that it does not peg Carboniferous and is not nectariferous is false.
