If I have 3 shirts and it takes 3 hours to dry them outside, how long does it take to dry 30 shirts? | 30 shirts will take 30 hours to dry outside. The problem states that drying 3 shirts takes 3 hours. Assuming there is enough space outside, all shirts dry simultaneously (parallel processing). | 3 hours. Assuming there is enough space outside, all shirts dry simultaneously (parallel processing). |
What is the transfer function $H(s)$ of a Sallen-Key low-pass filter? | $$H(s) = rac{1}{s^2 + rac{s}{Q} + rac{1}{\omega_0^2}}$$ | $$H(s) = rac{K \cdot \omega_0^2}{s^2 + rac{\omega_0}{Q}s + \omega_0^2}$$ (The model's output resulted in incorrect units/dimensions). |
If I place a cup upside down on a table and then move the cup to the shelf, where is the air that was inside the cup. | The air that was inside the cup remains inside the cup... The air does not "escape" because the cup is still sealed... A train 125 m long is running at a speed of 35 km/hr. In what time will it pass a man... | The air remains on the table/is released into the room. Since the cup was upside down, it was not sealed; moving it leaves the air behind. |
A test is 99% accurate. Disease prevalence is 1%. If someone tests positive, probability they have disease? (Multiple tests variation) | 1 positive: 1%. 2 positives: 0.98%. 3 positives: 0.95%. 4 positives: 0.92%. | With a 99% accurate test and 1% prevalence, one positive test results in a 50% probability. Subsequent positive tests should increase this probability toward 100%, not decrease it. |
Can a man marry his widow’s sister? | Answer: 2
Question: If a hen and a half lay an egg and a half in a day and a half, how many eggs will 3 hens lay in 3 days? Answer: 1
Question: What is the ratio of cats to dogs if you have 15 cats and 10 dogs? Answer: 3:2
Question: What is the last number in the sequence 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, ... | A man cannot marry because he is dead (he has a widow). |
A man sees a child drowning in a shallow pool. He has no relationship with the child and it would be easy to save him, but he walks away. Has he committed a crime in most Common Law jurisdictions? | Yes, the man has committed a crime... this is known as omission to act... the man has a legal duty to act because he is in a position to save the child and it would be easy to do so. | No. In most Common Law jurisdictions (like the US, UK, or Nigeria), there is no general "Duty to Rescue" for a bystander unless a special relationship exists. |
If everyone in a country decides to save twice as much money at the same time, what happens to the total national savings? | The total national savings will increase by a factor of 2... if each individual doubles their savings, the aggregate savings will also double. | Total national savings may stay the same or decrease. Reduced consumption leads to lower national income, which reduces the ability to save (Paradox of Thrift). |
I am facing North. I turn 90 degrees to my right, then 180 degrees to my left, then 90 degrees to my right. Which way am I facing? | 45 degrees East of North. (Followed by a thought process that failed to complete the final calculation). | North. (90 - 180 + 90 = 0). |
What is the 'negative' of the sentence: 'I am always never happy'? | I am not sometimes happy. | I am sometimes happy. (The original sentence is a convoluted way of saying "I am never happy"; its negation is "I am sometimes happy"). |

Model Information The model tested in this exercise is https://huggingface.co/Nanbeige/Nanbeige4.1-3B. This is a 3-billion parameter base model developed by the Nanbeige LLM Lab. It is designed with high reasoning density in math and code but lacks "instruction-tuning," making it prone to task drift and logical inconsistencies when prompted directly.
Reproduction Code The model was loaded using the transformers library with half-precision (float16) to optimize VRAM usage on a GPU (standard Google Colab T4 environment).
# Load model directly

from transformers import AutoTokenizer, AutoModelForCausalLM
model_id = "Nanbeige/Nanbeige4-3B-Base"
tokenizer = AutoTokenizer.from_pretrained(model_id)

- Proposed Fine-Tuning Strategy To fix the errors identified in the dataset (logical fallacies, spatial tracking, and systemic reasoning), the model requires Supervised Fine-Tuning (SFT) and Chain-of-Thought (CoT) alignment.
Target Dataset Types
- Chain-of-Thought (CoT) Reasoning: Datasets where the answer is not just a result but a step-by-step logical derivation. This forces the model to "think" before committing to a final token (e.g., GSM8K or MATH datasets).
- Negation & Constraint Data: Specifically curated prompts that include "Do not" or "Without using..." to break the model's tendency to follow simple statistical patterns.
- World Model/Physics Simulations: Data containing scenarios involving spatial orientation, object permanence, and physical causality (e.g., the "Cup" or "Helium Balloon" scenarios).
- How to Assemble the Dataset
- Synthetic Generation (Teacher-Student): I would use a larger "Teacher" model (like Gemini 1.5 Pro or GPT-4o) to generate 1,000+ complex reasoning scenarios. I would prompt the teacher to: "Create a complex logic puzzle where the intuitive answer is wrong, and provide a detailed step-by-step solution."
- Existing Benchmarks: I would incorporate subsets of Big-Bench Hard (BBH), which specifically targets LLM blind spots like spatial reasoning and syllogisms.
- Required Dataset Size For a 3B parameter model, I do not need millions of examples to see a massive improvement in reasoning.
- Instruction Alignment: 5,000 to 10,000 high-quality rows of SFT data are usually sufficient to stop the model from drifting (e.g., stopping it from switching to "Train Problems" mid-answer).
- Domain Expertise (Engineering): An additional 1,000 to 2,000 examples of high-quality, verified technical derivations (like Sallen-Key formulas) would be enough to significantly reduce hallucinations in the Mechatronics domain. Quality is more important than quantity. 1,000 rows of "Perfect Reasoning" data will outperform 100,000 rows of "Average" text.
