You looked in the dictionary and saw that Carl did not understand the word correctly.
Explanation:
The word "disseminate" does not mean "to listen" as Carl understood it, but it does mean the act of spreading something over an object or region. This word is associated with the act of semar, that is, spreading seeds on a land. In this regard, this word takes on the meaning of expelling something in an external environment that can be large or small. This word can also be a synonym for the word "disclose".
"Themes may be specific to one culture or apply to multiple cultures" is the only statement that is true, since themes can vary widely both in subject and interpretation by the reader.
