Which excerpt from Silent Spring best appeals to readers’ pathos?

A.So it had been from the days many years ago when the first settlers raised their houses, sank their wells, and built their barns.
B. The town lay in the midst of a checkerboard of prosperous farms, with fields of grain and hillsides of orchards where, in spring, white clouds of bloom drifted above the green fields. In autumn, oak and maple and birch set up a blaze of color that flamed and flickered across a backdrop of pines.
