In one sentence, describe what the following article is about: There are many papers for which no historical context is needed, but if historical context can help clarify things to the reader, a historical review introduction can be very helpful. These introductions are usually used for papers written about a historical time period or topic, a historical critique of a piece of literature, or a long-standing problem that people throughout the ages have tried to address. Outline or review a few key historical facts that offer the reader any essential information he or she might need in order to understand the topic of the paper. These pieces of information should not only provide context about the topic, but should also indirectly present the general topic itself. In doing this, you will demonstrate the the reader how your topic fits into the historical account you present in your introduction. The information provided thus far will be fairly general, so you need to focus the end of your paragraph on a single thesis statement that you will use to define the rest of your paper. A thesis statement is a single sentence that defines a specific point or idea about a broader topic that your entire paper is built around. With this type of introduction, your thesis statement should cause the reader to view the historical facts you just presented in a specific light or through a specific lens. In effect, your thesis statement should tell the reader why the facts you presented before it are important to keep in mind.
Summary: Determine if a historical review could be helpful. Provide factual and historical context about the the topic. Narrow your thoughts down to a thesis statement.

In one sentence, describe what the following article is about: If you're feeling sticky, rinse off in a cool or warm shower right after you tan. Use a mild soap or body wash to cleanse away any lotion, sweat, or dirt that's stuck on your skin. After you rinse off the soap, pat yourself dry with a clean towel. Don't take hot showers immediately after you tan because they can dry out your skin. It's best to avoid exfoliating after you tan because it will remove the top layer of skin, making your skin appear lighter. Squeeze a quarter-sized amount of lotion onto your hand, then slather it over your body. Massage the lotion into your skin to help it absorb. Add more lotion to your palm when necessary. Pick a thicker moisturizer, like a cream. Look for one that has natural oils, shea butter, or cocoa butter for added moisture. Alternatively, try a lotion that's made to be used after sun exposure. However, avoid petroleum jelly because it can lock in heat. Hydrated skin looks healthy and supple. Tanning can dry out your skin, but water rehydrates you from the inside. Make sure you're drinking extra water every day while you're tanning. This will help keep your skin looking youthful and hydrated. If you're also very active, you may need more water. If you're not sure how much water to drink, talk to your doctor for the best advice. Cool showers and moisturizer will keep your skin moist, which reduces flaking and peeling. When you shower, set the water on cool and keep it short. Then, apply an even layer of moisturizer over your entire body. Consider using an illuminating lotion in the morning to boost your glow. These work like regular lotions but leave your skin looking shiny. You can find an illuminating lotion at your favorite beauty supply store or online. If your skin is looking a little red, cool it down with a cool towel or a cool shower. Then, apply a thin layer of aloe vera gel over the sunburn to replenish lost moisture and help it heal faster. Additionally, drink a lot of water to help rehydrate your skin. While your skin is healing, stay out of the sun to prevent further damage. If your sunburn hurts, take over-the-counter NSAIDs, such as ibuprofen (Advil, Motrin) or naproxen (Aleve). Just check with your doctor first.
Summary: Rinse off in the shower to remove lotion, sweat, and grime. Apply moisturizer to your skin after tanning to prevent dry skin. Drink 10 to 12 cups (2.4 to 2.8L) of water daily to stay hydrated. Extend your tan by taking cool showers and moisturizing. Care for a mild sunburn with a cool towel and aloe vera.
