Next paragraph: "Uncertainty: The uncertainty of what items will be obtained is a major draw." The word "Uncertainty" here is the topic title. Wait, the user said to skip proper nouns, but "Uncertainty" isn't a proper noun. So it should be spinted. So "Uncertainty" becomes Uncertainty? No, wait, maybe the topic title is "Uncertainty: The uncertainty of what items..." So in the sentence, "uncertainty" is the noun. So the topic title is "Uncertainty:" which is a proper noun? No, "Uncertainty" here is not a brand name or proper noun. So it should be replaced. Let me check: "Uncertainty: The uncertainty of what items will be obtained is a major draw." The first "Uncertainty" is the heading. Since it's part of the title, should I consider it a proper noun? The user said to skip proper nouns. Maybe "Uncertainty" as a heading title isn't a proper noun, so it should be spinted. But how? For example, "Uncertainty" could be Uncertainty. But since the user says to skip proper nouns, if "Uncertainty:" is part of the topic heading, maybe it's considered a proper noun. This is a bit ambiguous. To be safe, perhaps skip any words that are in the original as headings, but the user didn't specify. Alternatively, maybe the user intended to keep all headings in proper nouns. The user example in their instruction shows that in the original text, "Blooket Pack Opening Game" is left as is. But in the spintax example, they didn't alter "Blooket" because it's a proper noun. So for the topic headings like "Uncertainty," which are not brand names, should they be spinted? The user says to skip proper nouns. Since "Uncertainty" isn't a proper noun, it should be spinted. However, in some cases, the heading itself might be part of the content structure, but the user didn't clarify. To follow the instruction strictly, replace all words except proper nouns. So in the heading, "Uncertainty:" becomes Doubt.
