index_start = 0
index_end = len(df)
step = 100
max_workers = 2

        ##Task
        You are a Mathematics teacher. Your task is to reason and identify the ConstructName and SubjectName and then the misconception behind the user input Incorrect Answers with the Question.
        ConstructName is Most granular level of knowledge related to question, appears to describe the specific mathematical method or procedure used to solve the question. It explains the technique or approach needed to reach the answer.
        SubjectName is More general context than the construct, represents the broader mathematical topic or category that the question belongs to.
        Misconceptions are a mistake in conceptual understanding and they have relations with all the applications of those concepts. For example, a single misconception on the connections among proportional relationships (part/whole, part/part, whole/part) can cause problems in identifying those patterns in drawings and can be the cause of failing to realize all parts must be of equal size, therefore associating the denominator of the fraction with the total number of parts regardless their size.
        Answer concisely what misconception it is to lead to getting the incorrect answer.
        Do not use "The misconception is" to start your answers.
        Do not mention the concrete details of the question or answers. 

        ##User input
        Question: The question text
        A: multiple choice answer A text
        B: multiple choice answer B text
        C: multiple choice answer C text
        D: multiple choice answer D text
        Correct Answer: The correct answer text

        ##You should answer in the following JSON format
        {
            "ConstructName": "here writes the constructName",
            "SubjectName": "here writes the SubjectName"
            "MisconceptionAName": "here writes the answer A's misconception.",
            "MisconceptionBName": "here writes the answer B's misconception.",
            "MisconceptionCName": "here writes the answer C's misconception.",
            "MisconceptionDName": "here writes the answer D's misconception.",
        }
        """, # system prompt,
    default_temperature = 0.5,
    max_tokens = 256,
)

3.3 配置输出路径

        if not system_prompt:
            system_prompt = self.default_system_prompt
            
        if not temperature:
            temperature = self.default_temperature

        chat_response = self.client.chat.completions.create(
            model=self.model,
            temperature=temperature,
            messages=[
                {"role": "system", "content": system_prompt},
