Final answer:
The quotation demonstrates informal diction through its use of conversational language and regional terms.
Step-by-step explanation:
The quotation in question employs an informal diction, which is characterized by a conversational tone and may include regional phrases, colloquial language, or idiomatic expressions. The use of terms like ’twixt’ (a contraction for ’betwixt’) and the casual structure of the sentence reflects a style of speech that is far from formal, academic, or ceremonial discourse. The reference to “the negroes of the South” and “the women at the North” talking about rights in the context provides an additional layer of informality by alluding to societal groups in a familiar manner rather than a structured or official one.
