Problem: Article: 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.
Summary: Consider your family history. Consider your vision. Consult an optometrist.

INPUT ARTICLE: Article: To create a Nether Portal, you'll need at least ten obsidian blocks. Make a hollow standing rectangle, 5 blocks high and 4 blocks long (corners are not necessary; you can use any block as a stand-in). Then strike the inside of the rectangle with flint and steel. The empty inner space should turn purple and start to make interesting sounds. Stand in the portal and wait 4 seconds to be transported into the Nether. Make sure you have your flint and steel for relighting the portal in case it breaks from a ghast and plenty of food to keep yourself well-fed. A Nether Fortress is a structure in the Nether that contains Nether Wart and a Blaze spawner. They can be somewhat hard to find, so it could take a while. Blazes drop Blaze rods, which are needed for making potions and getting to the endgame. You will need a lot of Blaze rods. Nether Wart is a key ingredient in potions, and it only grows on Soul Sand, so collect some Soul Sand (it's brown with a face-like pattern) and try farming it in your base. Nether Wart can be found naturally occurring in nether fortresses in two small patches alongside stairs going upwards. This will let you brew potions, which will help during the final boss fight.

SUMMARY: Build and light a Nether Portal. Enter the Nether. Find a Nether Fortress. Kill Blazes and gather Nether Wart. Craft a brewing stand.

In one sentence, describe what the following article is about: A fiber brush is useful because it can easily enter the grooves of the record to remove dirt. Additionally, the type of fiber easily drains static electricity which is responsible for attracting dust. To use, spin the record slowly while holding the brush over the vinyl. Special brushes can be purchased at your local music store or online. Use the brush to clean your records both before and after each record use. Don't forget to clean the dust off of the brush between uses too. Avoid using a T-Shirt or towel as this can damage the surface of your vinyl. There are pre-formulated cleaning products available both online and at local music stores, but you can also make a safe and affordable cleaner at home. Combine distilled water, isopropyl alcohol, and a couple drops of laundry detergent #without fragrance or dyes#, spray onto the vinyl, and use a microfiber cloth to wipe in a circular motion until the vinyl is dry. Combine 12 oz distilled water, 2 oz alcohol, 2 drops free and clear laundry detergent, into a spray bottle. It's important to use distilled water because it doesn't have any minerals that could be harmful to the record. Vinyl record vacuums provide a deeper clean than brushing and cleaning products alone. The vacuum sucks the debris out of the grooves with as little friction as possible. In addition, vacuums are able to apply a thin layer of cleaning fluid which dissolves oils and further protects the record. Each record vacuum is different so consult included with the device to learn to operate the device correctly. As an added bonus, the vacuum also helps to dry the record in an even fashion.
Summary: Use a carbon fiber brush. Try using a cleaner. Purchase a vinyl record vacuum cleaner.

In one sentence, describe what the following article is about: Whether you're tiling flooring or a backsplash, you want to mark the midpoint of the surface. This is to ensure that you're starting with the focal point of the room and that the tile feels symmetrical across. For flooring, you want to mark both the X and Y axis along the flooring in order to find the exact center of the room. Make chalk lines and double check the angles with a carpenter's angle. For a backsplash, you only need to find the horizontal middle, but mark this middle with a vertical chalk line down the wall. Use a carpenter's level to ensure the line is straight. With the floor prepped and the center marked, you can lay out the design of the tile. Start with the center gridline(s) and place additional tiles leaving the appropriate amount of room for the spacers, which will later be grout lines. For a backsplash, you will have to measure the exact space and lay the tiles out on the ground to match it since you cannot hold the tiles to the wall to check the design. For floor tiling, you can use the space you left for the grout to chalk in an entire grid for the project if you so choose. You will not be able to mix the thin-set for the entire project at once. Instead mix small batches in a five-gallon bucket. As you get going, you'll gain a pretty quick understanding of the pace you go and how much you use. Whatever you mix must be used within two hours. Regardless of whether you're installing floor or wall tiling, the thin-set should have the consistency of mashed potatoes when you mix it. Start with the area where you measured your initial chalk lines and spread enough thin-set to place two or three tiles to start. Use the edge of a V-notched trowel at roughly a 45-degree angle to spread the thin-set. You want to have an evenly, thinly covered space before putting down a tile. You want to actually scrape the trowel along the surface slightly to achieve the even spread. There will be slight furrows in the thin-set from the notches in the edge of the trowel. They are supposed to be there as they help air escape as the mortar sets. Place the first tile flush with your chalk centerline(s). For a backsplash, the process is easiest to do in rows. For a flooring job, it's easiest to start at one of the 90-degree angles in the center lines and work in quadrants based on those lines. As you place the tiles, make sure you're putting spacers between each to help keep consistent lines for grouting later. Every two or three tiles, use a carpenter's level to ensure flat, even placement of the tiles. If you want to take extra precautions to maintain the level surface, you can also purchase a leveling system, which consists of threaded pegs that go between the spacers and knobs that you can gently tighten down against the tops of the tiles to help perfectly level them and hold them in place. Don't worry if any thin-set ends up on the top surface of a tile as you trowel it. You can use a damp sponge to wipe it away. As you work toward the edges of your surface, you will likely have to cut some of the tiles to fit them. Take the exact measurement to which you need to cut the tile accounting for any spacers and transfer the measurement to the tile with a pencil. Then use a wet saw to make the cuts. If you are unfamiliar with how to use a wet saw, then you can find more at Use a Tile Saw. Since the saws aren't cheap, you will probably prefer to rent one from a hardware store for your project. For dealing with placing tiles around electrical outlets, you can find more information at Tile Around Outlets.
Summary:
Mark the midpoint of the area to be tiled. Lay out the tile design. Mix your thin-set mortar. Apply the thin-set to a small area. Apply the first tiles. Place spacers. Check for level placement. Wipe excess thin-set as you go. Cut tiles around baseboards.
