B．the trend of population growth will keep unsteady until the destruction of Earth
C．demographic growth will follow a certain pattern of ups and downs

参考答案：A进入在线模考
  定位：根据题干信息词a power fuse定位到第一段最后一句。
解析：该句将人口增长问题与保险丝作类比，说人口增长就像“一根又长又细的电力保险丝，时而稳定燃烧，时而又断断续续，直到最终达到电荷限度，爆炸了”。由此可推断，人口增长到最后将导致“保险丝的毁灭”，即人类的毁灭，故A项为答案。人口爆炸虽然会导致毁灭性问题，但与地球的毁灭无关，故B项被排除。其他两项本文未提及。
