In one sentence, describe what the following article is about: Once you've found speakers, don't buy them blind if you can help it. First rap your knuckles against the speakers. The speaker should feel solid and give you back a solid sound. If it sounds hollow now, it'll sound hollow when you try using it to play your entertainment at home. If you're buying speakers online, you can search for reviews or tests of the speakers, but to some degree you're shopping blind. Check that all the plugs work, then listen to the sound. Stand close enough, about ear-level to the front of the speakers. Judge if the internal components give you the sound you desire. The tightness of the covering over the speaker as well as the material of the speaker cone change the sound. Listen for any distortion, fuzziness, or crackling. If the outer enclosure is wide or loose, the sound reverberates too much inside the speaker. If the enclosure is too tight, the speaker rattles and the sound distorts. Cones are made of varying materials such as aluminum and polypropylene and push out air to make sound. Turn the settings up to volumes and frequencies you'll use at home in order to judge the speaker's sound range. If possible, give the sound quality a personal test. Good test songs are ones you know well that you have available on a CD or other format where the song's quality hasn't been compromised. Queue up the tracks. Listen for sound quality as well as the problems, such as if the vocals and instruments sound off. Test different features by using a variety of songs, such as ones that include a strong bass, quiet vocals, or instruments. Quality speakers may help you experience parts of the songs you've never heard, including small details like fingers sliding on strings or covered-up instruments. You may be able to use a music device such as an iPod, but transferring the song file to the iPod lessens the quality and doesn't give you the most accurate speaker test. A home test puts the speakers in the environment you want. Set the speakers up where you intend on having them. Play your music, movies, TV shows, or whatever else you intend on listening to with them. This is a good time to play your music too if you didn't do it before. Relax. Even if the speaker seems impressive at first, stay attentive. Is this one you can listen to for a while, or does the sound quality make you want to turn it off? Test it with your amplifier if you can. Speakers and amplifiers all have their own sound characteristics. The best combinations usually come from complementary qualities. For example, a mellow sound balances a bright sound. Remember that sound quality is personal and objective. Your needs influence what speaker is right for you, so don't let any salesperson pressure you into a decision. Before you buy the speakers, make sure the store has a friendly return policy. This is even more important if you're shopping online, since you don't get a chance to test the speakers in person and have to wait through shipping. Many companies will let you return the product for full price two weeks to a month after the purchase date. Keep your receipt and original boxing on hand until you're sure that you're keeping the speakers. Always keep and refer to the warranty information. The warranty gives you the right to quality assurance and a refund for a faulty product. Most companies accept returns for manufacturing flaws and dissatisfaction, not damage related from installation, use, or wear and tear.
Summary: Knock on the frame. Turn on the speakers. Play your music. Listen at home. Return bad speakers.

Green onions often come in plastic bags or are held together in bundles with rubber bands. Take all of the packaging off of the onions so that they are loose. Removing the packaging will allow the green onions to be removed from the bundle more easily and will minimize the chance of the onions being damaged by the rubber bands. In order to keep the green onions firm, they need to be kept in humid conditions. Wrapping them in a slightly damp paper towel will provide the humidity they need without adding so much moisture that they begin to rot. To make sure that the paper towel is not too wet, you can wrap the onions in a dry paper towel and then sprinkle a bit of water over the top of the towel. To keep the moisture around the green onions, the bundle should be placed in a plastic bag. This will ensure that the humidity created by the damp paper towel is not removed by the refrigerator. The plastic bag can be placed loosely around the bundle of onions. It does not need to be completely airtight. The vegetable bin is a good place to keep your green onions. However, because the green onions are in a plastic bag, they can be kept anywhere in your refrigerator. When you use some of your green onions, be sure to re-moisten the paper towel if it has dried out. Then place the bundle back in its plastic bag and put it all back in the fridge.

One-sentence summary -- Remove any packaging from the green onions. Wrap the onions in a damp paper towel. Place the towel-wrapped onions in a plastic bag. Put the bag in your refrigerator.

Problem: Article: Even for professionals, the type of clubs used matters. The type of clubs you choose depends on if you're at a beginner, intermediate, or advanced level. A set of three woods and eight irons is sufficient if you're a beginner. Most club sets will work for a beginner. Make sure the clubs fit your strength and posture. Once you reach the intermediate level, a good set of clubs are ones that have been fitted for you. Sometimes bigger clubs are better because it means greater inertia. You can use any type of ball, but some balls are better than others. You want a ball that will go the farthest distance. Yardage is more important than spin. Look for a ball that is not too light or heavy. Ask for the advice of an employee at your local sports equipment store if you're not sure which golf balls to choose. It's not necessary to go for the most expensive option if you're just playing for fun. Taking golf lessons is a sure way to improve your game. They are especially helpful for beginners. Golf lessons can help you learn etiquette, improve technique, learn technical aspects, and familiarize yourself with your equipment.

As with any game, you need a certain level of fitness to maintain the ability to play well. To keep fit, you can stretch, go to the gym, and/or enjoy any other physical activity. Stretch your hamstrings, quads, arms, and back before playing. Try to go to the gym at least twice a week. For physical activities, you can run, do yoga, or play other sports. Only do as much physical activity outside of golfing as you are comfortable with. Don't put too much strain on your body.
Summary:
Choose a good set of clubs. Choose a good ball. Take lessons. Keep fit.
