When someone tells you to “explain something,” they are asking you to give a detailed description of a topic or idea. This means that you should provide facts and evidence to help explain your point. For example, if someone asked you to explain why it’s important to wear sunscreen, you could provide facts about skin cancer rates and statistics about how much sunscreen can reduce the risk of sunburns. You could also include an analogy about how sunscreen is like an umbrella for your skin that helps protect it from the sun’s UV rays. As a fun fact, sunscreen has been around since the ancient Egyptians, who used an ointment made of rice bran, jasmine and lupine oils to protect their skin from the sun.
