Question 77·Medium·Text Structure and Purpose

The following text is adapted from a contemporary magazine article about pollinators.

In the popular imagination, modern farmland is an expansive quilt of crops, each square buzzing with industrious honeybees. Yet when ecologist Lina Perez walked the perimeter of a 500-acre cornfield last summer, she heard almost nothing but wind. The low hum we associate with agriculture, she explains, is often recorded near hedgerows and wildflower margins, not in the monoculture itself. Scientific surveys back up her experience: fields planted with a single crop support far fewer pollinators than do smaller, more varied plots. The disparity is no mystery. Corn, wheat, and soy offer bees little nectar, and pesticides further discourage visitors. Still, Perez is optimistic. “If we stitch native plants back into the edges of these fields,” she says, “we can restore both the music and the health of our farms.”
