As polar ice continues to recede due to climate change, policymakers have increasingly advocated for the development of Arctic maritime infrastructure as a means to mitigate strategic vulnerabilities in global trade logistics. A recent policy analysis contends that expanded investment in northern shipping corridors (including the construction of ice-hardened ports and specialized vessels) would reduce dependence on chokepoints like the Suez Canal, thereby enhancing the resilience and efficiency of trade between Europe and East Asia. The report concludes that, given recent disruptions in southern sea lanes, Arctic development constitutes a necessary strategic hedge for long-term stability in transcontinental shipping.
Polar ice receding due to climate change , there is advocation by policy makers to build Arctic maritime infrastructure to mitigate global trade logistics....
reduce dependence on chokepoints like Suez Canal... Arctic development constitutes a necessary hedge for long term trans continental shipping
use negation test and weaken the conclusion..
Which of the following is an assumption upon which the argument depends?
A. Arctic sea routes will
not offer sufficiently reliable navigability over a sustained portion of the year to serve as a practical substitute for traditional passages such as the Suez Canal.
this breaks the conclusion ; correct option
B. The marginal gains in shipping efficiency associated with polar transit will
not outweigh the capital costs and environmental risks involved in developing northern maritime corridors.
capital cost is not discussed in argument ; irrelevant to argument
C. Current shipping patterns are
not sufficiently rigid that infrastructure investment, rather than route flexibility, is required to mitigate future disruptions.
not on the lines of argument in discussion
D. Southern trade chokepoints are
unlikely to remain vulnerable to geopolitical or environmental disruptions over the next several decades.
does not weaken the conclusion
E. Major actors in transcontinental shipping will
not adopt route decisions primarily based on considerations of long-term strategic resilience rather than short-term operational costs.
there is no such info given of impact route will have if not adopted by major players
OPTION A is correct
