I want to make the case for (D) Kendra explicitly says accessing WiFi "requires stopping for a considerable length of time." Gerald's reasoning shows the opposite: he likens it to enjoying music on someone's radio as you walk down the street, which can't take a considerable length of time, you're walking by. So Gerald is committed to "not necessarily considerable time," Kendra says the opposite, and that's a direct disagreement.
