Okay, let's tackle this query step by step. The user wants me to swap every word in the given text with three variants using the format opt2, keeping names unchanged. First, I need to make sure I understand the exact requirements. They mentioned that names should remain the same, so I have to preserve any proper nouns like "Quotex" or "demo account".

"Increased trading efficiency: A Quotex demo to live script PDF can help you execute trades quickly and efficiently, maximizing your trading potential."

Also, I need to check for proper nouns. Words like Quotex, demo, and live should remain unchanged. The user also mentioned to convert each word, not phrases, so each individual word is considered separately.

But I need to make sure that the spintax is correctly applied. For each word in that part, replace with synonyms. But since the user might not want that, perhaps they want the entire product name as-is. However, the instruction says to convert each word, so I must do it.
