Final answer:
The phrases 'an error of interpretation' and 'a misinterpretation of the law' reflect Susan B. Anthony's belief that she was legally justified in voting, a view later overturned by the Supreme Court. Option (b) accurately describes how her actions were based on a legal misunderstanding, not a deliberate lawbreaking.
Step-by-step explanation:
The phrases "an error of interpretation" and "a misinterpretation of the law" as used in the text about Susan B. Anthony refer to the incorrect legal understanding or application of the law. In this context, option (b) is the most accurate as it states that Anthony did not intentionally break any laws as she believed the laws, as written, allowed her to vote. This interpretation was based on the argument that all citizens should have the right to vote, but this was later overruled by the Supreme Court, which held that explicit legislation or a constitutional amendment was required for women to receive the vote. Therefore, the mistake Susan B. Anthony made was a legal misunderstanding, not a careless error or felony.
