Passage 8 Often mistaken for insects, spiders actually belong to a different classification of creatures, called arachnids. They’re insects’ worst enemies. Although a few species, such as the black widow and the brown recluse, are dangerous, the majority are harmless to humans. Moreover, they can be helpful. Pest control, for example is just one of the many ways spiders can help us. They kill far more pests than commercial insecticides do. In the future, perhaps if farmers employ armies of spiders to protect their fields, our grocery bills will be lower and our soil and water and food will have fewer pesticide remains.

Unlike many people think,

a) Spiders can be used in insecticide industry

b) The black widow is a dangerous species of the spider

c) Spiders are the worst enemy of insects

d) A spider is not a kind of insect at all
