In one sentence, describe what the following article is about: It's easier to process and remember information if you break it up into bite-sized chunks. Instead of trying to memorize an entire chapter of your textbook, focus on one short section or key piece of information at a time. For example, if you're trying to remember vocabulary for a language class, don't try to memorize more than 7-8 words at a time. If you're studying from a textbook, it can be helpful to work with the structure of the book. Textbook chapters are usually divided into shorter sections that each provide a manageable amount of information. Focus on understanding and remembering one section before moving on to the next. It can be helpful to alternate between studying different subjects, so that your brain compartmentalizes the information more effectively. Switching between topics that are very different from each other can help keep your brain from getting bogged down with trying to remember too much about one subject (or 2 very similar subjects) at once. Additionally, switching between topics will help you avoid getting burned out on any one topic. For example, memorize a poem, then move on to studying some algebra rules. Try spending about 50 minutes on each topic, then take a break for about 15 minutes before going on to the next one. Taking breaks will boost your productivity and help you concentrate. As you're listening in class or reading your text, write down important pieces of information. Don't write down every word you hear or read. Instead, summarize key concepts. This will force your brain to process the information and condense it to its most important elements. If you can, take notes with a pen and paper. Writing notes by hand engages your brain in a different way than typing on a keyboard, and makes you take a little more time to think about what you are writing down. If you like to doodle while you take notes, that's great! Doodling can help you pay attention and retain information. As you study each section of the material, take breaks to quiz yourself. You might do this by making flash cards, writing study questions for yourself, or doing the exercises or knowledge checks that are built into your textbook. If you're studying with a friend, you can quiz each other. Quizlet can be a great help for quizzing yourself, either alone or with a friend. You can create your own digital flashcards based on your course material, or you can use flashcards prepared by other members. One way to test yourself is to ask yourself basic questions about the material as you go. For example, "What is the main point of this section of the text?" Self-quizzing not only helps you get a better idea of how well you understand the material, but it also forces your brain to work a little bit harder to remember. When you're trying to remember something, repeated exposure is important. This method works best if you give yourself enough time between reviews that you start to forget what you studied. Reviewing after a little time has gone by flexes your memory muscles and helps you learn the material at a deeper level. When you're spacing out your review sessions, keep the intervals short at first, then gradually increase them. For example, if you studied something one day, sleep on it and do a little review the next day. Test yourself a couple days later, and then again a week after that. Try a study timer app like SuperMemo or Ultimate Study Timer to help you schedule your study intervals. One of the easiest ways to access memories is to create associations that trigger those memories. That might mean using an acronym to remember information (for example, ROY G. BIV for the colors of the rainbow), using a pun or word play, or creating a distinctive mental image. The most common mnemonic devices are creating acronyms that represent the words you're trying to remember, making an acrostic sentence where the first letter of each word represents what you're trying to remember, and using rhymes to remember. However, you can also use image association, especially if you're a visual person. Music is also a powerful memory trigger, so putting the information to a melody can be very helpful. There's a reason countless generations of kids have been taught the alphabet in song form! Your memory cue doesn't have to make sense to anyone but you. In fact, the weirder and more specific it is, the better. For example, if you're trying to remember the ancient Greek word hepomai ("to follow"), you might picture a cool cartoon cat singing "I'm hep! Oh my! Everybody follow me!" Teaching is one of the best ways to learn. To be able to explain something, you must be able to understand it yourself. You have to summarize and express the material in a way that is clear and understandable to another person, and doing so can help you absorb and understand the material better.
Summary: Break the material down into small pieces. Switch between different topics. Take notes. Test yourself. Space out your review sessions. Create memory cues, called mnemonic devices. Explain the material to someone else.

In one sentence, describe what the following article is about: The stored air is unsafe to breath and can be flammable. Always release the air outdoors, away from other people. Keep your clothing, hair, and jewelry away from the tank's hose. Also, keep the tank away from open flames. For their safety, avoid letting children operate the tank. Slide the air hose over the brass fitting near the pressure gauge. It should fit on the opposite end of the small, ringed spout you used to fill the tank. Connect the hose's other end directly to the item you wish to inflate. An air hose usually is included with the tank when you purchase it. You can get new hoses at home improvement or auto parts stores. Look near the brass fitting to find a small, handy wheel. Turn the wheel counterclockwise to open the tank's valve. You should hear air flowing out of the tank right away. Air will continue to flow until you close the valve again. Watch the inflatable object closely to ensure it is filled at a safe level. Over-inflated items are liable to burst. When an item is inflated to the correct size, it will feel firm to the touch. It should not bulge or appear near bursting. Listen closely for any hissing coming from the tank, since this indicates that air is still flowing. Make sure the valve is closed completely. When you're ready, detach the hose to release any air stuck inside of it. If you plan on storing the tank for a while, stay safe by letting all the air out of it.
Summary:
Release the air in a safe, well-ventilated area. Connect the air hose to the tank and inflatable item. Turn the tank's wheel to the on position. Inflate the item to a safe size. Spin the valve clockwise to shut off the air flow.
