The two cases provided in the document involve different dataset formats. Which one should we choose when we do fine-tuning without CoT?

1、Qwen3 (14B) Reasoning + Conversational notebook (recommended)

Explain what boolean operators are, what they do, and provide examples of how they can be used in programming. Additionally, describe the concept of operator precedence and provide examples of how it affects the evaluation of boolean expressions. Discuss the difference between short-circuit evaluation and normal evaluation in boolean expressions and demonstrate their usage in code. 

Furthermore, add the requirement that the code must be written in a language that does not support short-circuit evaluation natively, forcing the test taker to implement their own logic for short-circuit evaluation.

Finally, delve into the concept of truthiness and falsiness in programming languages, explaining how it affects the evaluation of boolean expressions. Add the constraint that the test taker must write code that handles cases where truthiness and falsiness are implemented differently across different programming languages.<|im_end|>

Boolean operators are logical operators used in programming to manipulate boolean values. They operate on one or more boolean operands and return a boolean result. The three main boolean operators are "AND" (&&), "OR" (||), and "NOT" (!)

{'output': '1. Eat a balanced and nutritious diet: Make sure your meals are inclusive of a variety of fruits and vegetables, lean protein, whole grains, and healthy fats. This helps to provide your body with the essential nutrients to function at its best and can help prevent chronic diseases.\n\n2. Engage in regular physical activity: Exercise is crucial for maintaining strong bones, muscles, and cardiovascular health. Aim for at least 150 minutes of moderate aerobic exercise or 75 minutes of vigorous exercise each week.\n\n3. Get enough sleep: Getting enough quality sleep is crucial for physical and mental well-being. It helps to regulate mood, improve cognitive function, and supports healthy growth and immune function. Aim for 7-9 hours of sleep each night.',
