Answer 1

Answer: (B), (D)

Lightning is impossible because air is a poor conductor of electricity.

• Lightning is one of the natural phenomena whose occurrence cannot be predicted.
• Not possessing an open umbrella in hands during lightning actually helps. Because the tip of the umbrella provides a target point for the lightning strike.
• Lightning is a huge electric spark. Even though air is a poor conductor of electricity, there is enormous amount of electric charge in a lightning strike to penetrate through the air and hit the ground.
• Lightning rods are always placed atop the buildings that are very tall, like skyscrapers.
