Locust swarms have ravaged much of Suwathia, resulting in the loss of vital agriculture. A multinational company has recently proposed using metarhizium, a fungus that invades the exoskeleton of the locust, causing a swift death. The government of Suwathia argues that the one means of application of metarhizia—from an airplane—will require a great amount of the fungus, which is difficult to acquire. Given that the locusts propagate rapidly, the government maintains that only a complete annihilation of a locust swarm will have the desired effect.

Which of the following, if true, best argues in favor of the multinational company's plan to drop metarhizium over locust swarms?
  • AMetarhizium promotes the growth of a strain of bacteria that fosters root development in the crops that the locusts consume. 分析该选项
  • BSome swarms of locust can cover over 100,000 square miles. 分析该选项
  • CIf all of the locusts are not destroyed, Suwathia will lose millions of acres of crops. 分析该选项
  • DAn airplane must fly several kilometers ahead of a swarm of locusts to ensure that the metarhizia is correctly deployed upon the rapidly moving swarm. 分析该选项
  • EOnly one metarhizia-infected locust is necessary to lead to the demise of an entire swarm, since metarhizia can easily spread within a swarm. 分析该选项
