(答案→)specialists/experts
解析：
【小题1】考查名词。根据some修饰可数名词的复数，故用specialists/experts.
【小题2】考查副词。这里用词作状语，故用annually.
【小题3】考查非限制性定语从句。先行词是前面的整个句子，故用which.
【小题4】考查形容词。这里是固定短语on the other hand在另一方面。
【小题5】考查形容词。这里修饰名词disasters故用形容词natural.
【小题6】考查固定句式。it’s obvious that……很显然是……这里是固定句式。
【小题7】考查名词。根据that’s half a century,所以应该是几十年decades.
【小题8】考查固定短语。at random随意地，胡乱地。
【小题9】考查动名词。因为介词by应该用动名词，故用abusing.
【小题10】考查固定短语。result in导致，这里根据上下文应该用现在时。
