In one sentence, describe what the following article is about: Using a sling reduces movement of the arm and the injured shoulder while it heals.  Aside from purchasing an appropriately-sized sling, you can also make one with a meter-length cloth. Fold the cloth diagonally, arranging it into an elongated triangle that can be wrapped beneath the forearm of the injured arm and secured around the opposite shoulder. Secure the injured arm at a comfortable angle across the person’s chest (roughly horizontal), with the sling’s strap over the opposite shoulder. Perform this maneuver as gently as possible to avoid straining the injured arm. It is important to make sure that the sling feels comfortable, so you may need to make some adjustments. The entire forearm up to the hand should be supported by the sling. The sling should not be too tight or placed too high up either. If the sling is too high, then you may experience discomfort and tension in your shoulder. The cold temperature will actually reduce blood flow to the injured shoulder, which can help reduce any pain and swelling following an injury. Icing with compression is more effective in reducing tissue temperature than icing alone.  Wrap the ice pack in a towel or other cloth before wrapping it to your shoulder as directed previously, though with slightly less compression. Apply the cold pack for no more than 20 minutes. For the best results, remove the cold pack after 20 minutes, let the injured area rest for 20 minutes and then reapply the cold pack for another 20 minutes. If the injured shoulder becomes numb at any point, remove the cold pack and repeat the compression wrap process before re-applying the cold compress. Do not apply ice directly to the surface of the skin. This can lead to an increased risk of frostbite. Always wrap the ice pack in a towel first. A hot compress will stimulate blood flow to the injured shoulder, which is vital to the recovery process. This will also relax the muscles and reduce any muscle pain. A hot compress can also improve the flexibility of the tendons and ligaments in the injured shoulder.  Do not use a hot compress if the injured shoulder is swollen. It may cause more swelling. Hot compresses are available in multiple forms. Some create warmth via electric power, while others need to be microwaved or simply shaken. A rubber hot water bottle is best. Whatever you use, be careful that it does not become dangerously hot. As with a cold press, wrap or hold the hot compress in some sort of cloth before bandaging it to the shoulder as previously directed, though again, with less compression than you had used without an icing or heating element. Only apply a hot compress to the injured area for 20 minutes at a time.
Summary: Place the arm in a sling. Adjust the sling as needed. Ice the injured shoulder if recently injured. Shift to a hot compress after 48 hours.

In one sentence, describe what the following article is about: Use these questions as a guide to help you focus on the important and relevant material. As you are skimming the chapter, ask yourself if the material you are reading is answering these questions. If it is not, then skip it. Look for key words like “effects,” “results,” “causes,” “versus,” and “pros and cons,” for example. These key words will clue you into the chapter’s thesis or main idea. Knowing the main ideas beforehand will help you identify sections of the chapter that need careful reading. Highlight and refer back to the main idea or thesis so you can stay on topic. Rephrase section headings and subheadings into questions to help you focus on the important ideas being presented. If the section heading says, “Kramer’s Three Social Laws,” then rephrase it into a question by saying, “What are Kramer’s three social laws?” Then read the information that answers this question. Remember that bolded or italicized headings and subheadings contain clues to the most important information. If you understand these two sentences, then just skim or skip the paragraph. If you do not understand the first and last sentences, then read the entire paragraph. Make sure to slow down when you encounter complex paragraphs and sentences. This way, you will be able to fully understand what the author is trying to articulate in the paragraph. Skim the book for important concepts, people, places, and events. These are usually bolded or italicized. If you understand a concept, then you can skip the contextual information that explains it. Read the supporting text and contextual information only if you do not fully understand a concept. Ask some of your classmates if they are willing to do this. If they are, assign sections of the chapter amongst one to three other classmates. Each classmate should be responsible for their section. Make sure that you all can come to an agreement about each person's responsibilities. For example, devise a plan where each student in the group reads and writes a detailed outline for their respective section. Then, have everyone complete their outline by a certain date like the end of the week.
Summary: Examine the questions at the end of each section or chapter. Read the chapter intro and final summary. Look carefully at section headings and subheadings. Read the first and last sentence of paragraphs. Pay attention to important concepts and details only. Break up the chapter with your classmates.

In one sentence, describe what the following article is about: You will need a solid business plan to present to any investors and the best place to start would be with determining your basic cost of operations. This will outline and help you determine how much money is needed to produce the product or offer the service you intend to offer or produce. It includes production costs, shipping, taxes, worker's wages, rent for workspace, etc.  Knowing your cost of operations will be vital to determining if your business will be profitable, since you will need to make more than this baseline in order to remain in business. Be realistic. How many people will realistically use your business? How much will they pay to use your services? If either number is too small in comparison to how much it will cost you to stay in business, then you should reconsider or change your plans. You will need to plan ahead for all of the problems which can get in the way of running a business.  Evaluate your competition; if their market share or product offering is too strong and stable, then you will have a very hard time breaking into the market. No one will want to buy an equally priced or more expensive version of a perfectly good product or service which already exists. You will also need to explore the associated regulations and laws, especially regarding taxes. You should ask your local state authorities, as well getting information from the IRS.  Make sure there are no prohibitive costs, such as equipment which is too expensive to make the business profitable. For example, cars didn't take off until Ford figured out how to make them cheap by building more efficient equipment.
Summary:
Determine your cost of operation. Determine your potential market. Determine impediments.
