the fact that the variance does not occur if the buyout occurs and the row occurs is not right.
sent1: the variance occurs. sent2: if the ambushing Pipridae occurs the variance does not occur. sent3: the buyout happens. sent4: that the variance occurs is triggered by either the rowing or the ambushing Pipridae or both. sent5: that the variance occurs is prevented by that the rowing and/or the ambushing Pipridae happens. sent6: the variance happens if the buyout happens and the rowing happens.
