It's important to note that "insolent" itself is not a homonym. It has a specific meaning and spelling.
Here's why this is a bit of a trick question:
* Homonyms are words that sound alike but have different meanings and spellings. The word "insolent" is not part of a pair of homonyms.
* The wording "insolent talk" is meant to trick you into thinking of a word that sounds like "insolent" but has a different meaning. There isn't a word that fits this criteria.
