IN THE EPILOGUE, WHAT PART OF THE DESCRIPTION SUGGESTS THE PASSAGE OF TIME?

From the text:

The sign said WELCOME TO TREEGAP, but it was hard to believe that this was really Treegap. The main street hadn't changed so very much, but there were many other streets now, crossing the main street. The road itself was blacktopped. There was a white line painted down its center.

"Look, Mae. Ain't that where the wood used to be? It's gone! Not a stick or a stump left! And her cottage—that's gone, too."

"Had a big electrical storm, though, about three years ago now or thereabouts. Big tree got hit by lightning, split right down the middle. Caught fire and everything. Tore up the ground, too. Had to bulldoze her all out."
