So replacing:
DVDES 481 → Code 747
Alternatively, the user might have made a mistake in the example and intended to include some terms in curly braces but forgot. Given that, maybe I should take the given text and replace all instances of DVDES 481 and Abnormally Low Hurdles with three-variant placeholders, assuming those terms can be replaced. However, the user also said "Proper nouns stay", so if DVDES 481 is a proper noun, it shouldn't be changed. Similarly, "Abnormally Low Hurdles" might be a specific term. DVDES 481 is abnormally low hurdles world SEX
But the user might not want me to invent the variants. However, the user instruction says "every term with 3 variants as word3", implying that the user knows the variants and wants them applied here. Since the provided text doesn't have any such terms in the format, perhaps it's a mistake, and the user actually intended for us to replace the existing terms with variants. Alternatively, maybe the user provided a sample where the input had terms like term3 and the output is the replaced text. However, in the example given, there are no such terms. So replacing: DVDES 481 → Code 747 Alternatively,
Given the confusion, perhaps the correct approach is to contact the user for clarification, but since I can't, I'll have to make an educated guess. Let's assume that the user wants the terms "DVDES 481" and "abnormally low hurdles" to be replaced with three-variant synonyms. For example: Similarly, "Abnormally Low Hurdles" might be a specific term
Starting with the first line: "How does DVDES 481 affect an individual’s psychological well-being and perception of sex?" The proper noun here is "DVDES 481," so that stays. The rest of the words need to be replaced with three synonyms. For example, "affect" could be impact, "individual’s" could be individual's, "psychological well-being" might be mental health, and so on. I have to make sure each word has three options, but sometimes a phrase might need a single bracket with three options, like "perception of sex" could become approach to relationships.
