In one sentence, describe what the following article is about: Keeping yourself hydrated is important while your body is fighting infection, and drinking fluids with a warm temperature can help soothe your sore throat and keep the phlegm, the substance you cough up when you have bronchitis, loose and easier to expel. Try these warm fluids to help you get through bronchitis: Warm water with lemon and honey. Heat up a mug of warm water and add lemon juice and honey to taste. The honey coats and soothes your throat, and the lemon provides vitamin C and other nutrients. Chamomile, peppermint, or another herbal tea. Herbal teas, especially those made to help treat sore throats, serve the dual purpose of hydrating your body and treating your symptoms. Warm soup. Chicken broth or soup is nourishing and soothing. Garlic soup is another healing option that helps treat the symptoms of bronchitis. Saute minced garlic in a little olive oil, add chicken or vegetable broth, heat it to a simmer, and drink it hot. Gargling warm saltwater can help soothe your irritated throat membranes. Stir a teaspoon of salt into 8 ounces of warm water. Gargle the water and then spit it out. Repeat this a few times throughout the day. Do not swallow the water after gargling. Since bronchitis is an infection in your lungs, it can make you feel extremely tired. Listen to your body and take a rest, especially in the first few days of the infection, when your chest feels heavy and it's difficult to breathe. Your lungs need time to heal. At the beginning of the infection, when it's at its worst, take a few days off of work or school. Rest in bed or on the couch, and try not to go anywhere that will require you to exert yourself. Exercising while you have a lung infection can make it worse. Avoid running, swimming, biking, and other exercises that lead to heavy breathing while you have bronchitis. Bronchitis can make your chest feel heavy and painful, especially when you're coughing frequently. Applying heat can help ease the pressure. Try one of the following methods of heating your chest: Fill a hot water bottle with water and lay it on your chest. Use a heating pad on your chest. Place it over your clothing so it doesn't overheat your skin. Cover yourself with an electric blanket. Take a warm bath or shower. When your lungs are irritated, hydrating them with warm, moist air helps sooth your bronchial passageways. If you allow your throat to dry out, your lungs can become more irritated, prolonging the infection. Try the following methods for breathing humid air: Use a humidifier. Humidifiers are machines that add moisture to the air in a room. They're available for purchase at drugstores. Boil a pot of water on the stove. The steam produced from the boiling water can increase the room's humidity. Use a nebulizer to breath in saline and purified water mists. Place a bowl of water on the radiator. The heat from the radiator causes the water to evaporate and humidify the air. Take a steamy shower or bath. Make sure the bathroom door is closed so you get the benefits of breathing in the moist air. Inhaling smoke can bring on painful coughing fits when you have bronchitis. It can also delay your lungs' healing process. Avoid smoking or inhaling secondhand smoke. Stay away from these lung irritants, too: Areas with excessive pollution, such as streets with high traffic volume. Areas with a strong chemical smell, like the inside of factories, hair salons, and gas stations. The act of coughing when you have bronchitis helps expel the infection from your lungs. Coughing up phlegm is a normal symptom. Do not take an over-the-counter cough suppressant because your lungs need to expel the phlegm that is in them. If your coughing is extremely painful or constant, you should see a doctor to make sure you aren't experiencing symptoms for something other than bronchitis. Often times pneumonia and bronchitis have similar symptoms. It is important to see a doctor in order to differentiate the two. Never take an over-the counter suppressant without first consulting a doctor.
Summary: Drink warm fluids. Gargle with warm saltwater. Get plenty of rest. Use a hot compress on your chest. Breathe warm, moist air. Avoid smoke and other lung irritants. Let yourself cough.

In one sentence, describe what the following article is about: Use a ruler or straightedge to draw a straight line inside the circle, from one edge to another. The points that you use don't matter. Label the two points A and B. The circles should be the exact same size. Make A the center of one circle, and B the center of the other. Space the two circles so that they overlap like a Venn diagram. Draw these circles in pencil, not pen. The process will be simpler if you are able to erase these circles later on. There will be a point at the top and a point at the bottom of the "Venn diagram" space created between the overlap of the circles. Use a ruler to make sure that the line protrudes straight through these points. Finally, label the two points (C and D) at which this new line crosses the rim of the original circle. This line marks the diameter of the original circle. This should clear up your work space for the next step of the process. Now, you should have a circle with two perpendicular lines running through it. Do not erase the center points (A and B) of these circles! You will be drawing two new circles. Use your compass to draw two equal circles: one with the point C at its center, and one with the point D. These circles, too, should overlap like a Venn diagram. Remember: C and D are the points at which the vertical line intersects the main circle. This straight, horizontal line should cut through the overlap space of the two new circles. This line is the second diameter of your original circle, and it should be exactly perpendicular to the first diameter line. The intersection point of the two straight diameter lines is the exact center of the circle! Mark this center point for reference. If you want to clean up the page, feel free to erase the diameter lines and the non-original circles.
Summary:
Draw a chord between two points. Use a compass to draw two overlapping circles. Draw a vertical line through the two points at which the circles intersect. Erase the two overlapping circles. Sketch two new circles. Draw a line through the points at which these new circles intersect. Find the center.
