Final answer:
Vindicated means to clear someone from blame or suspicion.
Step-by-step explanation:
In the given passage, the phrase that helps understand the meaning of the word 'vindicated' is 'were only exonerated.'
Vindicated means to clear someone from blame or suspicion, and being exonerated accomplishes the same objective. Since Elizabeth Johnson, Jr. was never exonerated, it suggests that she was never cleared or vindicated of the charges related to the Salem Witch Trials. In the context of the passage, her lack of direct descendants may have contributed to her never receiving exoneration.
