The table lists physical characteristics for five caves in the Karst Belt.
| Cave | Depth (meters) | Volume (million m^3) | Floor area (km^2) | Mapped passage length (km) |
| Azur | 180 | 40 | 24.0 | 55 |
| Boreal | 720 | 120 | 58.0 | 88 |
| Cinder | 790 | 180 | 51.0 | 120 |
| Dusk | 910 | 200 | 47.5 | 260 |
| Ember | 1280 | 600 | 73.0 | 160 |
For each of the following statements, select
Yes if it must be true based on the table provided; otherwise select
No.
• The cave with the largest mapped passage length also has the smallest floor area. Largest mapped passage length is Dusk at 260 km; the smallest floor area is Azur at 24.0 km^2. They are not the same cave. Answer:
No.
• Cinder has the median value across all four listed physical characteristics (depth, volume, floor area, mapped passage length). Sort each column and take the middle value (third of five). For depth, volume, floor area, and mapped passage length, the middle value in each case belongs to Cinder. Therefore, the statement is true. Answer:
Yes.
• The range of depths among the five caves is greater than 1000 meters. Depth range = max - min = 1280 − 180 = 1100 meters, which is greater than 1000 meters. Answer:
Yes.
Correct answer: The cave with the largest mapped passage length also has the smallest floor area.
"No"Cinder has the median value across all four listed physical characteristics (depth, volume, floor area, mapped passage length).
"Yes"The range of depths among the five caves is greater than 1000 meters.
