In one sentence, describe what the following article is about: Saliva and build up collect in the neck. Put the swab in the bell and then pull it through the neck on a string. This is the same process you used on the mouthpiece, requiring warm water, soap or detergent, and a bottlebrush or toothbrush to be used weekly. Dip the brush into the warm, soapy water and use it to attack the limescale. Rinse out the remainder under a faucet with lukewarm water. Again, this is optional, as the soap and water takes care of the bacteria well enough. Any leftover bacteria or odor can be finished with certainty here.  Pour Sterisol germicide into the neck so that it coats the inside. Let it dry in a clean place on a paper towel for a minute, then rinse it under lukewarm water. Either let it air dry or dry it by hand with a swab or towel before storing. Vinegar can be used here, too. After loosening the limescale with soap, water, and brushing, stop the mouthpiece with a cork. Surface cover any holes, prop the neck upright, then add either cold or lukewarm vinegar. After 30 minutes, rinse out the vinegar with soap and warm water, then dry it in air or by hand.
Summary: Run a swab through after use. Remove the limescale. Sterilize the neck.

This is a section that will conclude your research paper. Format it with 1-inch margins on all sides and a label “Works Cited,” centered at the top. All citations should be listed in alphabetical order below with double-spaces in between them. Use a hanging indent for each entry where the lower line is indented slightly. The MLA generally suggests that you use endnotes for internal citations and notes. Include a separate page prior to the Works Cited page for “Notes.” Each note should be started with a superscript Arabic number. The format for notes slightly differs as well. You'll need to put names first name first and generally use periods instead of commas. If you have incomplete information or if you aren't certain about a particular citation, contact a university librarian near you. You can usually either call or email. They should be able to offer guidance or suggestions based up the recent MLA guide.

One-sentence summary -- Follow basic formatting rules for the Works Cited page. Use an endnotes page, if possible. Reach out to a librarian for assistance with a difficult citation.

Q: Apply a small, quarter-sized amount of shampoo to your palms and work it into a lather. Then, apply the shampoo to your scalp and massage vigorously with your fingertips. Then, work the lather through your hair and rinse. Rinse hair thoroughly so no shampoo is left behind. Washing your hair should take about five minutes. Even though greasy hair looks and feels dirty, washing your hair every day will make your hair more greasy because shampoo strips hair of its nutrients and natural oils, causing your scalp to produce even more oil. Wash your hair every 2-3 days at the very most. This gives your hair enough time to replace the natural oils, so you're not producing an excess. If you usually shampoo your hair every day, it may take a few months for your scalp to stop overproducing oil after you change your shampoo habits. Use dry shampoo on the days you don't wash your scalp to help absorb excess oil as you transition. In addition to not shampooing every day, use a high-quality, gentle cleansing shampoo. Shampoos that are aggressive tend to irritate hair follicles, causing the scalp to produce more oil.  Common irritants include sulfates like sodium lauryl sulfate and sodium laureth sulfate, as well as silicones like dimethicone and cyclomethicone. You can find silicone and sulfate-free hair products in most drug stores, as well as specialty beauty and hair-care stores. Shampoos with salicylic acid, selenium sulfide, or ketoconazole are good for greasy hair. Salicylic acid helps reduce oil on the scalp. Oily hair does not need to be conditioned often. Condition every other time you wash or just once a week. Only use conditioner on the tips of your hair instead of the roots, where grease gathers more easily. Apply it by squeezing your conditioner into your palms and scrunching it into the ends of your hair. The best dry shampoos for greasy hair come in a powder form. Try not to use liquid dry shampoos. Massage the dry shampoo powder in your hair and on your scalp between washes to soak up grease and leave hair smelling fresh, but don’t use them more than once a day. It can be difficult to resist washing your hair after working out, but when your hair is wet with sweat, you do not need to wash it to feel clean again. Just rinse your hair in the shower to remove the salts from your sweat and use a bit of conditioner on your ends to detangle if necessary. If you don't have access to a shower, you can also use a spray bottle to wet your hair and blow-dry it instead of washing. Many hair products have silicone in them, which causes hair to be heavy and greasy. Try using fewer hair styling products in general. If you must use products, avoid ones with silicone. After one month, your hair should be less greasy from adjusting your shampooing methods. If changing your habits does not help at all, try seeing a dermatologist, who will most likely prescribe you shampoo or medication to reduce oil.
A: Shampoo properly. Wash your hair every 2-3 days. Use different types of gentle shampoos. Condition less often. Use dry shampoos between washes. Skip washing your hair after workouts. Style hair with without silicone or oils. See a dermatologist if you see no results.

Article: Use shallow bowls or disposable food lids. Make sure you use something you don't mind throwing away and then add instant potato flakes to them. Set them where you've seen evidence of rats so that the potato flakes will be right in their path. Make sure to put at least 1/2 cup (50 g) in each bowl so the rats will really chow down. For this to work well, they need to drink water after consuming the potato flakes. Typically, they're pretty good at finding water on their own, but you can also set out small bowls of water near the potato flakes. Rats are drawn to the food, so they'll come chow down on the dried flakes. Then, when they drink water, the subsequent bloating will eventually cause their deaths. Check on the bowls once a day at least. If they're not being eaten, you may need to move the bowls elsewhere. Alternatively, try adding 1-2 spoonfuls of sugar to the mix to make the food more enticing.
Question: What is a summary of what this article is about?
Place bowls of instant mashed potatoes in the rats' path. Make sure the rats have a source of water. Keep an eye out to make sure the flakes are being eaten.

Problem: Article: Electric start engines should be tilted down so that the propeller is in the water. This will allow the fuel to readily flow into the engine during starting. Keeping the engine tilted down also keeps the propeller safely in the water while starting. On rare occasions, boats are equipped with fully electric outboard motors. These motors still have electric starters, and the starting procedure is the same as the procedure for a fuel driven motor with an electric start. Electric engines require the key to be in the ignition before important features, such as the gearshift, will operate. Insert the key into the ignition slot, and if necessary insert the kill switch, too. This should enable you to shift the engine to neutral An electric motor may have a manual gearshift that you can move to neutral. Alternatively, you may have to move the throttle to the neutral position. This will allow you to start the engine. You start most engines by turning the key to the “On” position. Some engines will have a start button that you must push. Once the engine starts, release the key or button.
Summary:
Tilt the engine down. Insert the key. Put the motor in neutral. Turn the key.
