Answer

To determine which of the precautions listed is not correct in case a storm is accompanied by lightning, let's analyze each statement step by step:

1. **Do not take shelter under a tree.**
- This precaution is correct. Taking shelter under a tree during a storm is dangerous because lightning can strike trees, and you could be injured by the lightning or falling branches.

2. **Do not take shelter under an umbrella with a metallic end.**
- This precaution is also correct. An umbrella with a metallic end can conduct electricity, making it unsafe during a lightning storm.

3. **Do not take shelter in open garages, storage sheds, etc.**
- This precaution is correct as well. Open garages and storage sheds do not provide adequate protection from lightning, and being in such places can be risky.

4. **Do not take shelter in a bus in the open.**
- This statement is not correct. Taking shelter in a bus is generally safe during a lightning storm because buses are enclosed metal structures that can provide protection from lightning strikes.

Based on the analysis, the precaution that is not correct is:

**Answer: Do not take shelter in a bus in the open.**
