You need to plug in four electrical items, but the power point only has room for 1. What is the safest way to connect these items?
Correct Answer
B. Use a power board

Using a power board is the safest way to connect these items because it allows for multiple outlets to be used simultaneously. A power board typically has multiple sockets, which means that each electrical item can be plugged in separately without overloading a single socket. This reduces the risk of overheating or electrical fires that could occur if multiple double adapters are stacked on top of each other in a single power point.

From which direction should light fall?
Correct Answer
B. Side
Explanation
Light should fall from the side because it helps to create depth and shadows, which can enhance the visual appeal of the subject. When light falls from the front, it tends to flatten the subject, while light from the back can create silhouettes. However, side lighting can add dimension, texture, and drama to the scene, making it a preferred choice in many photography and cinematography setups.
