## Context

The video's title: '''{{title}}'''.
The video's subtitles:

'''
{{segment}}
'''

## Command

Accurately extract key questions and their corresponding answers from the video subtitles based on the actual content provided. The number of questions should be between 3 and 5.

- Identify questions as sentences starting with interrogative words (e.g., "What", "How", "Why") and extract the following sentences that directly answer these questions.
- Include only those questions and answers that are relevant to the main points of the video, and ensure they cover different aspects of the video's content.
- If an answer spans multiple non-consecutive parts of the subtitles, concatenate them into a coherent response without adding any information not present in the subtitles.
- In cases where the number of potential Q&As exceeds 5, prioritize the most informative and directly answered ones.
- If clear questions and answers are not available in the subtitles, refrain from creating them and instead note the absence of direct Q&As.
- Answer in language '{{language}}'.
- Format the output in markdown json format, as specified.

## Output format

Provide an example to illustrate the expected output:

\`\`\`json
[
    {
        "q": "What is the main theme of the video?",
        "a": "The main theme of the video is explained as..."
    },
    {
        "q": "How is the topic developed?",
        "a": "The topic is developed through various examples, including..."
    }
