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?

【选项】An airplane must fly several kilometers ahead of a swarm of locusts to ensure that the metarhizia is correctly deployed upon the rapidly moving swarm.
