Read the passage below:
In 1879, the steamship Strathleven successfully transported forty tons of frozen beef from Melbourne to London, proving that artificial refrigeration could conquer equatorial heat. While contemporary headlines hailed the voyage as an unmitigated triumph, shipping ledgers told a more sobering story. The ship’s compressed-air cooling apparatus consumed staggering amounts of coal, leaving scant cargo space for profitable freight, and erratic temperature spikes spoiled portions of the outer carcasses. The voyage demonstrated technical possibility, yet commercial viability remained a distant prospect.
Statement: The author's attitude toward the commercial readiness of early refrigerated steamships is best characterized as guarded skepticism.
