Question

What are some tools that might be helpful to track a lost team member during mountaineering?

• A. Water bottle
• B. Whistle
• C. Torch
• D. (b) and (c) above.

Answer 1

The correct option is D (b) and (c) above.

We can use torch and whistle to get the lost team member's attention. Whistle sound can be heard even after long distances, so the lost person can follow this sound. The person also can follow the torch light.
However, water bottle can not be used to track someone.
