Final answer:
The word 'impious' means lacking reverence or showing disrespect for things that are generally taken seriously or considered sacred, either in religious or broader contexts.
Step-by-step explanation:
The word “impious”, as used in paragraph 3, typically means showing a lack of respect for things that are generally taken seriously or considered sacred. In a religious context, someone who is described as impious may not follow or show proper reverence for religious practices and beliefs. In a broader sense, an impious act or comment could be one that is disrespectful toward any institution or idea that is held in high esteem. For example, if a character in a book speaks irreverently about a social custom or tradition, they could be characterized as being impious.
