Problem: Article: Connect a full sentence with a list using a colon. The colon sets off your information, making it easy to sort. Consider these examples: "I went to the store and bought a lot of fruit: peaches, apricots, grapes, kiwis, and nectarines. "You're missing everything: the pre-game, the party, and the afterparty." Colons can be used to join a full sentence with an explanatory noun, proper noun, or noun phrase. Use this to place a lot of emphasis on the noun. You can write, "My nightmare revealed to me my deepest fear: solitude." Another example could be, "The clouds broke to pour sun down on her favorite place in the world: her father's rose garden." To quote a full sentence or more, lead with a colon. Don't do this if you are only quoting a few words. Proper usage might include any of the following: 'In her poem "Houses," Laura Riding described the difference between lined and unlined panes of glass: "Windows give up their secrets, not mirrors."'
Summary: Precede a list with a colon. Set off a noun or noun phrase with a colon. Introduce a lengthy quotation.

Problem: Article: Fresh and clean water is an absolute must to your piranha's health. Replacing 10-20% of the water every week and cleaning tank walls and gravel can prevent a compromised immune system and also odor. Weekly maintenance shouldn't take more than 10 minutes. Write a schedule for yourself to clean the water at the same time each week so that you don't forget. Clean the aquarium more often if you notice excess wasteremember piranhas are messyor odor. Be aware that you shouldn't remove your piranhas from the tank if at all possible. Remember that piranhas generally attack when they feel threatened or are hungry. Protect your hands with a pair of heavy gloves when cleaning. If you absolutely have to remove your piranha from the water, place a bucket or large fish net in the tank and quickly place your piranha in a separate tank. Use a water changing device, or python, from a local pet store for best results. These hook up to a sink and make it easy to clean the tank. This can also minimize the risk of your piranha becoming aggressive with you. If you don't have a water changing device, gently remove each piranha and put them in a separate holding tank while you clean. This will allow you to clean the tank without stressing your fish or getting injured because the piranhas are stressed. Vacuum the gravel and remove any waste while using the water changing device or when the tank water is low and no piranhas are in the tank. The health and lifespan of your piranha is dependent on high water quality. Ensure proper pH and oxygenation by testing the tank water after every cleaning. Test tank water with a test kit that you can get at large retailers and pet stores. Test to figure out potential problems like low oxygen, high ammonia, and acidity. Fix any problems with the water. The pH level can range from 5.5-8.0. Use a chemical neutralizer to restore the pH levels if they are off. Oxygen saturation should exceed 70%. If it doesn't, you may need to replace your filter or filters. Use a thermometer to make sure the temperature is between 75 and 80 degrees Fahrenheit. If necessary, turn up the heater until you reach the optimal temperature range. Piranhas produce a lot of waste, which can also affect the water quality. Make sure you have a very strong filter or several small filters to stagger maintenance. If tank water gets dirty quickly, consider replacing your filters. Smell the water to see if it has a foul odor. This is a good sign you need to change the filters.
Summary: Clean the tank weekly. Maintain high water quality. Check the filters.

Problem: Article: The most common recommendation for dry eyes is to use rewetting drops or artificial tears. These eye drops can help lubricate dry eyes by replicating the composition and effect of real tears. If you use artificial tears, look for a brand that is preservative-free. The preservatives in regular over-the-counter drops or artificial tears can cause buildup on your contact lens and even cause you to develop an allergy. Wash your hands before inserting eye drops or touching your eyes in any way. Gently shake the eye drop container and remove the cap. Avoid touching the applicator tip so you do not contaminate it. Tilt your head back and hold the bottle upside down against your forehead, directly above your eye. Use your other hand to gently pull down your lower eyelid and eyelashes, and try to simultaneously raise your upper eyelid without touching it. Lightly squeeze the bottle until the desired number of drops fall onto your eye. Close your eye without squeezing it shut and gently dab at the outside of your eye with a clean tissue. Gently press on the inner part of your eye while your eyes are closed, and hold it for 30 seconds to prolong contact with the eye drops. Carry eye drops with you wherever you go if you are prone to dry or irritated eyes. Depending on the severity of your dry eyes, your doctor may recommend an anti-inflammatory agent. This may be in the form of eye drops (like Restasis) or steroids. Anti-inflammatory prescriptions will help treat dry eyes caused by chemicals/medications, heat, or certain autoimmune disorders. Some causes of dry eyes, like medications or certain medical conditions, are unavoidable. But other environmental causes can be avoided or diminished with proper planning and care. Wear eye protection if it is windy outside, and try to limit exposure to the wind. Avoid smoke. Try to avoid dry air. Use a humidifier at home if your heating system is drying out the air. Carry eye drops with you wherever you go if you are prone to dry eyes.
Summary: Use rewetting drops. Take anti-inflammatory agents. Prevent the causes of dry eyes.

Problem: Article: You can draw a line with sidewalk chalk on your driveway, mark your spot with a pen, or use any household object to indicate your place. Count your steps from 1 to 10 as you walk forward. For best results, try not to overthink your foot placement and walk normally. If you used sidewalk chalk to mark your starting point, draw another line at the edge of your shoe. If you used an object (such as a pen) to mark your starting point, drop another object at the tip of your right foot. This mark indicates your stopping place. Start your measurements where you took your first step, and use a ruler, yardstick, or measuring tape to find the distance to your last step. Use the smaller units of measurement on your measuring device, such as inches or centimeters (instead of feet or meters). Round your measurements to the closest inch or centimeter. For example, the distance may be 180.3 inches (458cm), which rounds down to 180 inches (460cm). Have a friend help hold your tape measure if you need a hand. Once you have the total number of inches or centimeters, you are 1 calculation away from determining your stride length. Divide your distance, and the number you get is your stride length! For instance, if your distance is 180in (460cm), you will get 18in (46cm) after you divide by 10. Your stride length is 18in (46cm) or 1.5ft (0.46m). If you want to ensure your measurements are as accurate as possible, repeat the process a few more times, and average the numbers together. To calculate your average, add up the total of all your stride lengths, and divide them by the total number of times measured.
Summary:
Pick a starting place and mark it with an item. Take 10 natural steps forward starting with your right foot. Make a mark in front of your right foot after 10 steps. Measure the distance between your starting and stopping point. Divide your distance in inches or centimeters by 10. Repeat this 2-3 times to find an accurate average.
