3. Distance travelled by a plane

- Description: The distance a plane travels is typically very long, such as across countries or continents.
- Units: cm / m / km
- Reasoning: Planes travel distances that are best measured in kilometers because these distances are extremely large.
- Answer: km

4. Width of a shirt

- Description: The width of a shirt refers to its horizontal measurement, such as from one sleeve to the other.
- Units: cm / m / km
- Reasoning: Shirts are relatively small objects, so their width is best measured in centimeters.

6. Length of a pair of scissors

- Description: Scissors are tools with handles and blades, and their length is the total span from one end to the other.
- Units: cm / m / km
- Reasoning: Scissors are small objects, so their length is best measured in centimeters.
- Answer: cm
