Which percentage corresponds to the chance of finding an explosive device when awareness exists?

• A. 5%
• B. 10%
• C. 20%
• D. 30%

Answer: (C)

Awareness changes how you search: when you know there might be an explosive device, you search more thoroughly, follow established procedures, and scrutinize items more carefully. This increases the odds of finding something, but it doesn’t guarantee you’ll locate every device because concealment, placement, and other factors can still hide threats. Among the given options, the one that shows a noticeable but not absolute improvement best matches this reality. Choices that imply only a tiny gain would understate the impact of awareness, while a very large gain would overstate it by suggesting near certainty. So the option reflecting a moderate increase in the chance is the best fit.
