To comply with new international maritime emissions targets, fleet operators are considering retrofitting existing bulk carriers with rigid wind-assisted propulsion sails. Sea trials demonstrate that installing these rigid sails reduces overall diesel fuel consumption on long-distance routes by up to twenty percent. Because of these fuel savings, shipping companies will fully recover the capital costs of retrofitting within three years of operation. Therefore, investing in rigid wind-assisted sail retrofits represents a more financially prudent strategy for fleet operators than transitioning immediately to experimental ammonia-fueled vessels.
In the argument presented, the boldfaced statement plays which of the following roles?
- It is an intermediate conclusion that is derived from evidence about fuel reduction and is used to support the argument's main conclusion.Cevap
- BIt is the overall main conclusion of the argument, for which all other statements serve as supporting evidence.
- CIt is a direct factual premise introduced to establish background context without requiring logical derivation from other claims.
- DIt is an unstated assumption required to demonstrate that ammonia-fueled vessels are currently economically unviable.
- EIt is a concession introduced to acknowledge a potential financial risk before the author pivots to the final position.
Cevap
The boldfaced claim functions as an intermediate conclusion, inferred from fuel consumption data and utilized as support for the main conclusion.
The correct answer accurately identifies the boldfaced statement as a subsidiary or intermediate conclusion. It is logically inferred from the empirical premise regarding twenty percent fuel savings, and it serves as the key intermediate reason supporting the author's ultimate conclusion that retrofitting bulk carriers is a more financially prudent strategy than adopting ammonia-fueled vessels.
