### Significant Figures and Percent Uncertainty

#### (a) Significant Figures Calculation
- **Question**: How many significant figures are in the numbers 999.0 and 1000.0?
  - 999.0: [Box to fill in number of significant figures]
  - 1000.0: [Box to fill in number of significant figures]

#### (b) Percent Uncertainty Calculation
- **Given**: If the uncertainty in each number is 10, calculate the percent uncertainty for each number. Provide the answer with 4 significant figures.
  - 999.0: **4.0%**
  - 1000.0: **4.0%**

#### (c) Meaningful Expression of Accuracy
- **Question**: Which is a more meaningful way to express the accuracy of these two numbers: significant figures or percent uncertainties?
  - [ ] significant figures
  - [ ] percent uncertainties (User is prompted to choose one option)
  
This exercise guides you through understanding the concept of significant figures and how to calculate and interpret percent uncertainties for given numerical values.
