Difficulty: EasyInference and Logical Deduction

Read the following passage carefully:

Inland water transport (IWT) in riverine basins offers a significantly lower carbon footprint per ton-kilometer compared to road freight. However, operationalizing IWT in seasonal river networks requires frequent dredging to maintain minimum navigable depths, which disrupts benthic ecosystems and increases long-term maintenance costs. Recent freight policies mandate that regional logistics hubs prioritize IWT only when river channels sustain natural depth thresholds without continuous dredging for at least eight months annually. In regions where seasonal water flow drops below these thresholds, multi-modal terminals are instructed to redirect heavy cargo to electrified rail transport rather than undertaking capital-intensive channel modifications. Consequently, multi-modal logistics planners must continuously monitor seasonal hydrology to ensure compliance with freight routing guidelines.

Statement: Based on the passage, regional logistics hubs are required to divert heavy freight to rail transport when river channels cannot maintain navigable water depths without continuous dredging for at least eight months of the year. Is this statement True or False?

Answer: Answer

Answer

The statement is True.
The statement is logically true because the passage establishes a direct conditional rule: IWT may only be prioritized if river channels maintain natural navigable depths without continuous dredging for at least eight months per year; otherwise, cargo must be redirected to rail transport.

Step-by-Step Solution

1
Identify the condition required for using Inland Water Transport (IWT) according to the passage.
IWT is prioritized only if river channels maintain natural depth thresholds without continuous dredging for at least eight months annually.
This establishes the strict threshold set by the freight policy.
2
Identify the mandatory alternative action when the depth threshold is not met.
Cargo must be redirected to electrified rail transport rather than carrying out channel modifications.
This shows the directive when IWT cannot fulfill the 8-month natural depth criterion.
3
Compare the statement with the extracted premises.
The statement accurately reflects the passage's rule that freight must be diverted to rail if continuous dredging is needed beyond the four-month allowance.
The inference is directly and strictly supported by the text.
