Answer:
by revealing Señor Vicente’s motivation for speaking at the meeting.
In paragraph 2, the author describes how Señor Vicente, despite being a retired man, decided to attend a meeting in which a younger generation was discussing the past and present of Valencia. The author reveals that Señor Vicente's motivation for speaking at the meeting was to correct some inaccuracies and misconceptions about the history of Valencia that were being spread by the younger generation. This revelation creates tension between Señor Vicente and the younger generation, who may not be willing to accept his corrections or may not respect his knowledge and authority.
