Read the following short passage and match each specific detail to its primary rhetorical function in the author's argument.
"Many urban planners argue that cities should invest heavily in public green spaces, citing numerous benefits. For example, Central Park in New York demonstrates how a large park can significantly boost surrounding property values. Furthermore, green spaces improve public health by providing areas for exercise and reducing air pollution. In fact, trees in these parks act as natural air filters, similar to how wetlands purify water. Critics, however, point out that maintaining these spaces requires substantial municipal funds, a valid concern given recent budget shortfalls in many cities. Nevertheless, the long-term economic and health benefits ultimately outweigh these maintenance costs."
