<div>Read the passage and answer the following question.</div>An investigator went to Central America to study oropendolas, which are communal nesting birds. Another species of bird, the cowbird, sometimes lay its eggs in the nests of oropendolas. Some of the populations of oropendolas throw the cowbird eggs out of the nest, and some don't. The investigator was interested in finding out why some birds would raise other species as their own but others would toss them out. By watching the nests closely, he found that blowflies lay their eggs in the nests of oropendolas and that the young larvae, maggots, feed on the young birds. If young cowbirds are in the nest, the precocious cowbirds eat the blowfly larvae, protecting the young oropendolas. In colonies of oropendolas that discriminate against cowbirds, throwing them from the nest, the blowflies are not eaten by cowbirds. These colonies of oropendolas build their nests close to a particular wasp colony, and the wasps eat the blowflies.<br> The relationship between the blowfly and the cowbirds that are associated with the non-discriminating oropendolas is one of</h2></div>
