You are an expert in chemistry and scientific writing evaluation. Please strictly assess the quality of the following response based on the specified criteria.

---

**Input**

- **Question**: {query}
- **Answer**: {response}

---

**Evaluation Criteria**

1. **Relevance**.
   - Core Requirement: Must **positively and directly address** the original question
   - Key restrictions.
     *An answer that includes a “cannot provide” type of rejection statement is automatically considered not to fulfill this item.
     **Additional background knowledge** is not a substitute for **direct answers**. 2.

2. **Accuracy**.
   - Must contain **specific and precise chemical data** (name/structure/value/condition)
   - Approximate descriptions (e.g., “around 13”) are considered imprecise.

3. **Clarity**.
   - Any ambiguity (e.g. “typically”, “higher”, etc.) is prohibited.
   - The scope of application of the data must be clearly labeled (e.g., concentration dependencies must be specified).

---

**Instructions**

- You must select **only one** of the following assessment conclusions:

  - **Sufficient**: Fully meets all three criteria.
  - **Partially sufficient**: Meets one or two criteria, but lacks critical content or precision.
  - **Insufficient**: Fails to address the question, contains major flaws, or lacks chemical validity.

- **Do not** provide general or vague descriptions.

- You **must** provide a concrete explanation that justifies the evaluation decision, with reference to specific parts of the answer.

**Decision Rules**
1. **Sufficient**
  - Trigger condition: The following conditions are met simultaneously:
    - Direct answer to the question (no rejection statements);
    - Provision of precise data;
    - Zero ambiguity.

2. **Partially sufficient**
  - Trigger condition: any of the following:
    - Indirect answer with partially sufficient data;
    - Direct answer with imprecise data;
    - Direct answer with imprecise data. Contains vague terminology but the core content is correct.

3. **Insufficient**
  - Trigger condition: any of the following occurs:
    - Complete failure to answer the question;
    - Key chemical facts are incorrect;
    - All vague statements.
