题目
Draco Petrochemicals moves tens of tankers in and out of the heavily trafficked Port St. George every day. The company’s success depends on its ability to transport large chemical shipments with minimum delays. Consequently, Draco is planning to replace its largest tankers with new SPNSR tankers, whose cutting-edge architecture minimizes the need for routine maintenance. The SPNSR tankers’ durability in this regard results in both lower maintenance costs and less time lost to maintenance stops.
Which of the following, if true, could present the most serious disadvantage for Draco Petrochemicals in replacing its largest tankers with new SPNSR tankers?
选项
A.The SPNSR tanker would enable Draco Petrochemicals to chart direct routes to destinations that currently require stops for maintenance.
B.Maintenance costs for deep-sea vessels are projected to decline over the next several years.
C.The cutting-edge architecture of the SPNSR tanker causes water current disruptions when leaving the harbor that force other ships to delay their departures.
D.None of Draco Petrochemicals’ competitors that use Port St. George is considering buying SPNSR tankers.
E.The durability of the SPNSR tanker would enable Draco Petrochemicals to eliminate maintenance at some of its destinations, but several mechanics would lose their jobs.
解析
Draco Petrochemicals(德拉科石化公司)每天有数十艘油轮进出交通繁忙的圣乔治港。该公司的成功取决于其以最小延误运输大型化学品货物的能力。因此,德拉科计划用新的SPNSR油轮取代其最大的油轮,SPNSR油轮的尖端架构最大限度地减少了日常维护的需求。SPNSR油轮在这方面的耐用性既降低了维护成本,又减少了因维护停靠而损失的时间。
以下哪项,如果为真,会给德拉科石化公司用SPNSR油轮取代其最大油轮带来最严重的不利?
- 核心论点:德拉科计划更换SPNSR油轮,依据是其“尖端架构减少日常维护需求”的特点,可降低维护成本、减少维护停靠的时间损失,最终保障“运输大型货物时最小延误”的核心目标。
- 正确答案方向:需找到一个选项,说明更换SPNSR油轮后,**会通过“间接/直接影响运输延误”或“意外增加成本/风险”等方式,严重损害公司“最小延误运输”的核心目标**(或带来其他足以抵消“维护优势”的严重负面后果)。
- 选项A:SPNSR油轮能让德拉科规划“当前因维护需停靠”的目的地的直达航线。 这是**优势**(减少停靠、提升运输效率),与“寻找劣势”的要求相反,排除。
- 选项B:深海船舶的维护成本预计未来几年会下降。 德拉科更换SPNSR的核心优势是“自身维护成本低”,即使未来其他船维护成本下降,SPNSR的成本优势仍存在;且该选项未体现“更换SPNSR的劣势”(与换船的负面影响无关),排除。
- 选项C:SPNSR油轮离港时的水流扰动会迫使其他船只推迟离港。 圣乔治港“交通繁忙”,其他船延误将加剧港口拥堵→德拉科的油轮进出港也会受此影响(港口拥堵导致自身运输延误),直接损害“最小延误运输”的核心目标,是足以抵消“维护优势”的严重劣势,符合要求。
- 选项D:德拉科的竞争对手(使用圣乔治港的)未考虑买SPNSR油轮。 竞争对手的决策与“德拉科换船的劣势”无关(换船的劣势需聚焦公司自身运输效率/成本),排除。
- 选项E:更换后几名机械师失业。 机械师失业属于“内部人员调整”,并非影响公司“运输效率/成本”的严重劣势(公司核心目标是“最小延误运输”,而非保留机械师岗位),排除。
综上,正确答案为C。
