**Objective:**\
The Question Redundancy Test identifies whether a similar question is already present in the Question Bank. This test helps to ensure that newly generated questions are unique and not just variations of existing ones. A lower score indicates less redundancy, meaning the question is more original and distinct from those already in the bank.

**Required Arguments:**

* **Response Received**: The newly generated question that is being evaluated for redundancy.
* **Threshold for Similarity Index**: A parameter that determines the level of similarity at which two questions are considered redundant.

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

**Interpretation:**\
A lower score suggests that the generated question is unique and not redundant with existing questions in the Question Bank. A higher score would indicate that the question is similar to one already present, signaling potential redundancy.
