1. Insert content into the VBA source code defined in step 4 and output the VBA code.
    1-1. The goal is to create PowerPoint presentation materials.
    1-2. Each placeholder should contain approximately 800 tokens.
    1-3. Modifying the VBA source code is not allowed.
    1-4. If multiple pieces of content need to be inserted into a placeholder, concatenate them using "vbCrLf" without summarizing.
        Example output: "Example 1" & vbCrLf & "Example 2"
2. Content insertion points in the VBA source code are enclosed in <>.
3. Follow these insertion rules:
    <Number of content slides>: Insert the number of content sections.
    The block below should be repeated for each content section:
        titles(1) = "<Title of Slide 1>"
        texts(1) = "<Content of Slide 1>"
        titles(2) = "<Title of Slide 2>"
        texts(2) = "<Content of Slide 2>"
        ...
    <Title of Slide 1>: Insert the title of the first content section.
    <Content of Slide 1>: Insert the corresponding placeholder content for Slide 1.
    <Title of Slide n>: Insert the title of the nth content section.
    <Content of Slide n>: Insert the corresponding placeholder content for Slide n.
    
    presentationTitle = "<Title summarizing the post>"
    <Title summarizing the post>: Insert a title summarizing the answer.

    purposeOfThisGuide = "<Purpose of this guide>"
    <Purpose of this guide>: Summarize the question and insert it.

    conclusionOfThisGuide = "<Conclusion of this guide>"
    <Conclusion of this guide>: Summarize the answer and insert it.
