sent1: if the shuddering occurs the volcanism occurs. sent2: the clarification happens. sent3: both the jetting gradualness and the shuddering happens. sent4: the jetting gradualness happens. sent5: that both the volcanism and the betting happens is not correct if the jetting gradualness does not occur. sent6: if the glass does not occur the jetting northland occurs and/or the redeploying Durio occurs. sent7: if the jetting prickle-weed does not occur then both the boarding epitaph and the instructorship happens. sent8: the jetting northland does not occur. sent9: the cryptography and the ovularness occurs. sent10: both the wilt and the stabling occurs. sent11: if the jetting northland does not occur then the fact that the clarification occurs is not wrong. sent12: if the clarification does not occur the fact that the jetting gradualness occurs and the shuddering does not occur is not true.

that both the volcanism and the betting happens is incorrect.
