How should one cross an area that is suspected of contamination?

Crossing an area suspected of contamination requires a strategic approach to minimize exposure to potential hazards. The highlighted choice emphasizes the importance of quick movement, which is critical in contaminated environments where the time spent in such areas can increase the risk of exposure to harmful substances. By avoiding depressions and vegetation, individuals reduce the likelihood of coming into contact with contaminants that may accumulate in those areas, as depressions can collect hazardous materials and vegetation can harbor biological threats.

The necessity for speed is tied to ensuring safety; moving quickly can help limit the duration of exposure. Vegetation and depressions might not only conceal contaminants but can also impede visibility and awareness of the surroundings. Therefore, the rationale for this approach is grounded in both the urgency of reducing potential exposure and the tactical advantage of being less vulnerable while traversing suspected hotspots.
