Final answer:
Priestley uses the older characters' attitudes and language in 'An Inspector Calls' to contrast with the younger generation, highlighting themes of social responsibility and the resistance to change exhibited by the older generation.
Step-by-step explanation:
J.B. Priestley presents the older generations in An Inspector Calls through their attitudes, language, and reactions to the Inspector's inquiries. The older characters, Mr. and Mrs. Birling and to some extent Gerald Croft, are depicted as self-centered, resistant to change and largely dismissive of the Inspector's assertions. Priestley uses the structure of the play, particularly the sharp contrast in attitudes between the generations, to underscore his themes of social responsibility and collective guilt. The rigid and complacent mindset of the older characters is exposed through their dialogue, which reflects their concern for maintaining the status quo and personal reputation rather than acknowledging the social crimes they've committed. This is in stark contrast to the younger generation, represented by Sheila and Eric, who show more empathy and a willingness to change.
