When comparing a ruler marked in millimeters to one marked only in centimeters, the following statements are true:
B. It can make more precise measurements.
D. Its measurements can have more significant figures.
E. It can make exact measurements.
**Explanation:**
- **B** is true because millimeters allow for smaller divisions than centimeters, enabling greater precision.
- **D** is true as measurements in millimeters can express more detail, thus having more significant figures (e.g., 10.5 mm vs. 10 cm).
- **E** is also true because a ruler measuring in smaller units (millimeters) can potentially measure distances more accurately to the exact millimeter.
**Note:** A and C are not necessarily true as the ability to make longer or more accurate measurements does not inherently depend on whether a ruler is marked in millimeters or centimeters; it is more about the level of detail and precision that can be achieved with the unit divisions.
