if the virologicalness happens then that the Yugoslavianness does not occur is correct.
sent1: that the virologicalness happens is prevented by that the Yugoslavianness occurs and the actinomycetalness happens. sent2: the warmingness does not occur. sent3: the Himalayanness does not occur. sent4: the Yugoslavianness occurs if the virologicalness occurs.
