Problem: Write an article based on this summary: Shelve books upright. Keep books out of direct sunlight and in a cool area. Keep your books clean.

Answer: Avoid shelving books too tightly or leaning against one another as this can cause lasting warping, structural damage, and cracking. When shelving, place books of similar height and length next to one another to avoid stressing the spine. Placing a book flat is an alternative to upright shelving. However, when shelving a book horizontally be sure to put as little weight on top of it as possible. Grab the middle of the spine when removing a book from a shelf to avoid damaging the head (top) and foot (bottom) of the spine. Place your books in a controlled climate to help prolong the book's quality. Sunlight, heat, and humidity can all have negative effects on the book's binding, structure, and page quality. Humidity can cause mildew to grow on your books. If you live in a particularly humid environment, and mildew begins to grow, simply wipe the mildew with a very dry cloth and leave the book in sunlight for 30-45 minutes. Be careful not to leave it longer as sunlight can cause the cover to fade. If a rare or fragile book grows mildew bring it to a specialist in book conservation. Clean your books regularly in order to prevent natural wear and tear and increase the quality of their storage. Dusting your books will help reduce permanent page and cover aging. Make sure to dust your books from the spine outward so dust does not settle behind the spine. Avoid storing books in plastic bags. Books need to breathe and plastic can cause molding or warping. Instead, try wrapping the book in acid-free cloth or purchases a book storage box.

Problem: Write an article based on this summary: Slap the dough between your hands (optional). Drape the dough on a fist and palm. Rotate your arms toward your body. Bring your hands up and around. Release the pizza. Follow through. Catch the dough. Repeat as necessary.

Answer: Slapping is an easier way to hand shape your pizza. Some chefs slap, some toss, and some start with slapping and finish with a toss or two. None of these methods are more correct than another. If you decide to slap, here's how it goes: Drape the dough over your palm and forearm. The more of your arm you use, the less likely the dough is to break. "Slap" the dough onto your opposite palm, letting it drape over your other hand and forearm. If your dough is in danger of tearing, let it drape gently instead of using force. Repeat this motion back and forth. Each time you "slap," the dough should rotate about one quarter turn. This rotation is vital for making the dough wide and even. If your dough looks strong and hasn't yet reached the desired size, it's time to adopt the tossing position. Extend your dominant hand as a flat palm, with fingers together. Keep your other hand in a fist to "anchor" the dough. Drape the pizza dough over both hands, supporting opposite sides of the dough. Rotate your arms inward to get ready for the throw. (If you are using your right palm, rotate your arms to the left.) This allows more rotation during the throw, imparting the spin that shapes the dough in the air. Bring your palm up and around, until the back of your hand is in front of your face. Follow with your fist to continue supporting the pizza, but focus on your palm, which will do the tossing. Practice this motion without tossing the pizza first, then try again with moderate speed during your toss. Start with a more gentle throw than you think you need. Too little force, and the pizza doesn't leave your hand. Too much force, and the pizza flies across the room. Bring the upward motion of your palm to an abrupt stop when it comes in front of your face. This will send the pizza flying upward a short distance. In the air, it should spin at the same speed your hands rotated. The force from spinning pushes the dough flatter and wider, without pressing out the air. Although your hand stops moving upward, it should still complete the arch of its movement after the pizza is released. Follow through by moving your palm around and out, as though swatting a fly in front of your face. A smooth follow-through ensures that your hand is rotating at the moment when you release the pizza. Don't worry too much about this for your first few tosses. It's more important to catch the falling pizza than to get the right hand shape. Catch the dough with both fists and forearms. Use as much of your forearm as you can, to avoid puncturing it. If you have a strong dough, you may be able to catch it on one fist, but this is risky for most recipes. If you tossed with your right palm, catch the dough mostly on your left arm. Expert dough tossers "catch" the dough on their fingertips, sending it spinning again without letting it rest. This is a complex technique that involves sending the dough in multiple trajectories and angles. It's best not to try this until you're a more experience pizzaiolo. If you slapped the dough or hand-stretched it heavily, you may only need one toss to get your pizza to the size you need. If you only used light hand-stretching, you may toss it several times. Once the pizza reaches the desired size, place the dough on a pizza screen, pizza stone, or baking sheet. You're ready to add the toppings. The dough is ready when you say it's ready. The size of your oven and personal preference for crust thickness are the only criteria you need when cooking at home.

Problem: Write an article based on this summary: Ask your RA or dorm advisor before using push pins. Use push pins if you have a drywall or wood wall in your dorm. Stick 4 push pins in each corner of the wall. Remove 1 push pin at a time to secure the tapestry on the wall. Add more push pins if your tapestry seems to droop.

Answer: The easiest damage-free way to hang a tapestry is with push pins. Push pins leave much smaller holes in the wall than nails or screws and are often allowed when decorating a dorm. That being said, some dorms do not allow push pinsask your dorm advisor before using them to make sure you don't damage the wall. Using push pins against your college's regulations can result in fees. Push pins work best with tapestries made of light fabrics. Push pins stick into drywall and wood easily and hold up over time. Plaster walls, on the other hand, are thicker and do not usually work with push pins. If your dorm has plaster walls, try a different hanging method (like adhesive hooks or velcro). Cork also works well with push pins, though having a wall made entirely of cork is unlikely. Measure the height and length of your tapestry with measuring tape. Position the 4 push pins apart at the distance you recorded. Do not push the pins too tightly into the wall yet, as you'll need to remove or reposition them as you work. Some tapestry will have tabs on each corner that you can hook on the pins, but others will need to be pinned to the wall. Remove a push pin from the wall and position the corresponding corner of the tapestry where the pin had been. Push the pin in the wall again to secure the tapestry corner, then repeat the process with the remaining 3 corners. Push down hard on the pin with your thumb to secure it in the wall. Reposition the push pins as you work if you miscalculated the distance of the tapestry. The larger your tapestry is, the more push pins it will probably need. If your tapestry bunches in the middle or the sides, use more push pins to secure the tapestry to the wall.

Problem: Write an article based on this summary: Consider your family history. Consider your vision. Consult an optometrist.

Answer:
Poor eyesight is typically genetic. So if both of your parents wear glasses, it is reasonable to assume you'll need them eventually too. Keep this in mind as you consider whether or not you need glasses. Ask your family members how old they were when they first started wearing glasses. Think about whether or not your vision seems to have changed over the years. Do you have more trouble viewing specific things than you did in the past? This is a sign that you need glasses. Specifically consider whether you have trouble viewing things that are far away or that are up close, as these are the two biggest problems with eyesight that people typically have. The ultimate way to determine whether or not you need glasses is to get an official eye examination from a licensed optometrist. They will perform tests on your vision and on your eyes in general to determine if glasses are a necessity for you. An optometrist, in addition to whether or not you need glasses, will also be able to tell you if there are any medical problems with your eyes.
