考查名詞的語義辨析。根據句意可判斷這兒應填入表示“範圍，程度”意思的詞，由此可排除選項B)rank(職銜;地位，社會階層)和選項D)limit(限度，限制)。選項C)range表示“變動範圍，變化幅度”，如：The speech covered a wide range of topics.這次演講涵蓋了一系列話題。The subject is outside my range.這個題目超出我所學範圍。顯然選項C)不符合句意。選項A) scale規模，程度，大小，如：They are preparing for war on：large scale.他們正在為戰爭做大規模的準備。從原文來看，選項A)scale符合題意。全句的意思是“當上層領導試圖掩蓋流行病的規模並輕視其影響時災難變得更加嚴重了”。
