**Objective:**\
The Topic Redundancy Test identifies whether any topics in the Q\&As generated are repeated. This test evaluates the uniqueness and variety of the topics covered in the response. A lower score indicates less redundancy, meaning the response is more varied and avoids unnecessary repetition.

**Required Arguments:**

* **List of Chunks of Context**: Sections of the context that contain the key information and topics that should be assessed for redundancy.
* **Response Received**: The content generated by the model that is being evaluated for topic redundancy.
* **Threshold for Similarity Index**: A parameter that determines the level of similarity at which two topics are considered redundant.

**Score Range:**\
0 (high redundancy) to 1 (low redundancy)

**Interpretation:**\
A lower score suggests that the response has less repetition of topics, which is desirable for varied and engaging content. A higher score would indicate that the response contains redundant information, possibly repeating the same topics multiple times.
