I think the user might consider "Fluid Mechanics Course" as a proper noun title, so I need to leave "Fluid", "Mechanics", and "Course" as they are. Then "Understanding the Fundamentals of Fluid Flow" is a subtitle. Let me proceed carefully.
I need to go through each part carefully. Let me start building the rephrased text step by step, making sure the synonyms make sense in context. Also, the format should have opt2 for each word, and only output the text without any formatting unless the user wants it. Wait, the user said "Only output text." So the final answer should have the rephrased words in the specified format, but the example shows the user wants the rephrased text with the braces. Wait, the original instruction says to rephrase all words with 3 synonyms in the format opt1, proper nouns stay, only output text. So I need to rephrase each word (except proper nouns) into three synonyms separated by |, within curly braces.
So, for "essential," synonyms could bevital. Wait, "ruling" doesn't fit here. Maybe "crucial|vital|essential." Wait, the user said three synonyms per word. Let me check each term one by one. fluid mechanics course
But this requires careful judgment. Since the user is asking for all words except proper nouns to be replaced with three alternatives, perhaps I should replace every word except those in proper nouns. Let me proceed by checking each word, and if it's not part of a proper noun, replace it. For example, "fluid" in "fluid mechanics" is part of a common noun phrase, so "fluid" can be replaced with liquid. Similarly, "mechanics" could be discipline. But some words may not have common synonyms. Let me proceed step by step.
So the task is to go through each word in the text, replace it with three synonyms in the specified format, and not touch proper nouns like "Fluid Mechanics Course". Also, the output should be text only, no other information. I think the user might consider "Fluid Mechanics
"course" →program. "essential" →important.
Similarly, "civil, mechanical engineering" are types of engineering, so they are common nouns and should be rephrased. I need to go through each part carefully
- "Fluid statics" is a proper noun, left as is. - "the study of fluids at rest" → "study" → investigation, "fluids" → gases, "at rest" → immobile - "including pressure and forces on submerged surfaces": "including" → entailing, "pressure" → compression, "forces" → effects, "submerged surfaces" → immersed areas
