Problem Analysis:

The task involves distinguishing between Qualitative (QL) and Quantitative (QNT) observations. Here's a brief explanation of the two types:

- Qualitative Observations: These are descriptive and non-numerical. They involve qualities, characteristics, or attributes that cannot be measured numerically.
- Quantitative Observations: These are numerical and measurable. They involve quantities, amounts, or values that can be expressed in numbers.
