I have to ensure that each word is replaced, but without altering any proper nouns like "Mastercam 9.1". Then, checking the next sentence: "Activate the software using a valid license or crack." "Activate" could be enable, initialize, launch. "Software" might be program, application, tool. "License" could be key, subscription, permission. "Crack" is a bit tricky since it's a term with negative connotations; maybe use workaround, unauthorized key, or bypass. Mastercam 9.1 Download
- Mastercam 9.1 (proper noun, leave) - is → was - a → a variety of - powerful → capable - CAM → CNC (but CAM is part of the acronym, so maybe leave as is?) Wait, the user says "Don't touch proper nouns", but CAM is an acronym. Is that a proper noun here? The phrase is "CAM software". Since CAM is an acronym for Computer-Aided Manufacturing, which is a field, so perhaps it's a technical term but not a proper noun in the text. But the user might want to leave it as is. Hmm. Maybe I should check if the user considers terms like CAM as proper nouns. The instruction is vague. However, since it's part of the software's title, maybe leave it. But the instruction says not to touch proper nouns. Let me re-express: Proper nouns are names of specific things like brands, products, etc. "Mastercam" is a proper noun. CAM is a category, not a proper noun. So replace "CAM" with synonyms? Maybe CAM doesn't make sense. Wait, "CAM software" is Computer-Aided Manufacturing software. The synonyms for CAM would be something else. Wait, maybe not. If the user wants to replace each word with 3 alternatives, then "CAM" can be replaced with similar acronyms or terms. But maybe not, because the user doesn't want to change proper nouns. Hmm. This is tricky. Let me assume that "CAM" here is a proper term that's part of the software's name, but actually, CAM is a standard term. So perhaps in this case, the user doesn't want to replace it because it's part of the software's title. But the user might not. Maybe I should leave it as is. So, the key is to not replace any proper nouns. Since CAM is a common acronym, maybe it's not a proper noun here, so replace it. Alternatively, maybe the user wants to leave all acronyms as they are. Hmm. Let me proceed with replacing it as per instruction.

I need to check each word for proper substitution, making sure the meaning stays intact and the options are valid. Let me go through each line carefully and ensure I don't miss any word. Also, avoid touching any proper nouns again. Let me confirm all changes meet the 3-alternatives rule without altering the structure. Once done, cross-verify with the example to match the style.
So first, I need to go through each word and replace it with three synonyms if it's a regular word. Let me start by taking the first sentence: "Mastercam 9.1 is a powerful CAM software that remains widely used today." Converted: a → an I have to ensure
