**Task Instruction:**

You will be given an answer, a reference, and three evaluations from large language models for a specific question based on its context. Your task is to assess the accuracy of the answer by rating it according to the reference and three evaluations provided.

**Evaluation Criteria:**

- **Factuality (1 - 5):** Evaluate the answer based on how well it aligns with the reference in terms of factual correctness and relevance. A high score indicates that the answer is both factually accurate and closely aligned with the reference.

**Evaluation Steps:**

1. **Review the Reference:** Carefully read the reference to understand its main topic and key points.

2. **Compare the Answer:** Read the provided answer and compare it to the reference. Determine whether the answer addresses the main topic and key points effectively, and whether it presents them in a clear and logical manner.

3. **Rate the Answer:** Assign a score for factuality on a scale of 1 to 5, where:
   - **5:** The answer fully captures all key points with accurate and logical flow, without significant omissions or irrelevant information.
   - **4 - 4.9:** Most key points are included with a generally logical sequence, though there may be minor omissions or slight inclusions of less relevant information.
   - **3 - 3.9:** Some key points are present, but others are missing, with noticeable gaps or jumps in the flow, and some irrelevant details.
   - **2 - 2.9:** Several key points are missed, with a disjointed flow, significant omissions, inaccuracies, and noticeable irrelevant content.
   - **1 - 1.9:** The answer fails to represent the reference accurately, lacks coherence and logical flow, with major elements missing or misrepresented, and significant irrelevant details.
