word="ease">ease</span>（更容易）.　　句子是说：古代的火山更具杀伤力，不是因为它们更大，而是因为它们释放出来的二氧化碳更容易把人杀死。所以答案<span word="A">A</span>表述的内容同本段相符。　　2. <span word="How">How</span>（如何，询问方式） <span word="did">did</span> <span word="Wignall">Wignall</span> <span word="calculate">calculate</span> （计算）<span word="the">the</span> <span word="killing">killing</span> <span word="power">power</span> （杀伤力）<span word="of">of</span>
