The table below presents operational metrics for 8 oceanographic research vessels participating in a global marine survey:
| Vessel ID | Region | Active Days | Fuel Efficiency (nmi/ton) | Grants ($M) |
|---|---|---|---|---|
| Triton-1 | Pacific | 240 | 14.2 | 3.8 |
| Nereus-4 | Atlantic | 215 | 18.5 | 4.2 |
| Proteus-2 | Pacific | 240 | 16.0 | 2.9 |
| Oceanus-7 | Arctic | 190 | 12.1 | 5.1 |
| Calypso-3 | Atlantic | 260 | 15.4 | 3.1 |
| Glaucus-5 | Pacific | 215 | 19.2 | 4.6 |
| Thalassa-9 | Indian | 260 | 13.8 | 4.0 |
| Doris-6 | Atlantic | 190 | 14.5 | 3.5 |
Based on the table above, evaluate whether the following statement is True or False:
"If the table is sorted primarily by Active Days in descending order, with ties broken by Fuel Efficiency in descending order, the vessel that ranks 4th from the top is Triton-1."
Cevap: Cevap
Cevap
True
Sorting primarily by Active Days descending places Calypso-3 and Thalassa-9 in positions 1–2, and Proteus-2 and Triton-1 in positions 3–4. Applying the secondary sort by Fuel Efficiency descending resolves the tie between Proteus-2 (16.0 nmi/ton) and Triton-1 (14.2 nmi/ton), placing Proteus-2 3rd and Triton-1 4th.
