Final answer:
False. The provided references discuss themes of unexpected social role reversals and critiques of societal values, but do not contain the specific scene referenced. Therefore, the assertion that Iago's lines involving societal status are the source of humor cannot be confirmed by the materials given.
Step-by-step explanation:
The question seems to center on whether the lines from a play involving Iago are humorous because they cleverly deflect Brabantio's accusation by highlighting status over morality. This is false since the provided excerpts do not include a scene with Iago and Brabantio. Instead, the provided references feature Cicero's criticisms of Piso's unexpected rise to power despite apparent lack of virtue or merit, the musings on the social standing and its influence on perceptions from 'Attic Nights', and Pliny discussing how fortune can turn senators into professors and vice versa, showing the ironies in societal roles.
The references also include the notion that a poet must possess both mathematical and creative skills to reason well, an interpretation of poetic critique from Glaucon's perspective, and commentary on Roman societal values and customs through satire and courtroom analogies.
The materials point out humorous and ironic situations but do not validate the humor in Iago's lines as it pertains to deflecting accusations based on social hierarchy.
