Problem: Article: The traffic cop will be the one calling out the commands, directing traffic by yelling, "Red light" or "Green light." The traffic cop is also the judge as to whether a child has moved on "red light." Additionally, the traffic cop can be considered the finish line, the goal of the game being to make it to the cop. If playing with a class, the teacher can start as the traffic cop. If the teacher doesn't wish to play, have a kid volunteer to be the traffic cop. Make sure the traffic cop has a loud voice so that everyone can hear the commands. This person can also be called a "stoplight" if you prefer. Whether you call them a traffic cop or stoplight, the function is the same. They will call out the commands and be the one in charge. There needs to be enough distance between the traffic cop and the kids to make the game fun and challenging. Have the traffic cop move at least 5m or 15ft away from everyone else. Wherever the traffic cop stands will be the finish line. If playing with older kids, make the game more advanced by adding more distance between the traffic cop and the other kids. You could even use the full length of a soccer or football field! Just make sure the traffic cop's voice can carry that distance. It is best to start closer together and gradually add more distance as everyone learns the game. Everyone besides the traffic cop should be on the starting line. They need to be lined up next to each other in a straight line so that no one has an advantage. Leave enough space in between each player so that they can run and move comfortably, perhaps a foot in between each player. The traffic cop should start by facing away from the players. They should not be able to see what anyone is doing to start. This is to ensure that they won't try to catch a particular player off guard.
Summary: Choose the traffic cop. Distance the cop at least 5m away from the other players. Form a straight line with the other players. Have the traffic cop face away from the other players.

INPUT ARTICLE: Article: Go for a sleeveless compression vest with a low neckline, which wouldn't be noticeable under a button-up or swim shirt. You can find compression apparel designed for gynecomastia online and at medical supply stores. If you have trouble finding a garment labeled for gynecomastia, go with a surgical compression vest, which people wear after chest operations to help incision sites heal. If you plan on swimming, check your product's label to make sure it can get wet. Most compression garments can be worn in saltwater. However, chlorine can damage elastic fabric, so don't wear a compression vest in a chlorinated pool. Men's shapewear and performance sportswear can also do the trick, even if they're not specifically designed for gynecomastia. While they're more expensive, some performance vests have cooling strips, which can help make wearing layers more comfortable. Find shapewear and performance apparel online, at athletic supply stores, or in the menswear section of most major department stores. Like compression garments, shapewear and performance apparel are usually made of materials that shouldn't be exposed to chlorinated water. A rash guard is a tight-fitting top worn by surfers and other water sports aficionados, and a swim shirt is a less fitted version. They're on-trend, so you might feel less out of place if you wear one. Many fashion brands manufacture swim shirts, and rash guards are available at any store that sells sportswear. You can also find either garment online. If a swim shirt alone doesn't conceal your chest, you could a wear one over a compression or performance vest. Remember that a garment with cooling strips can help keep you from getting too hot. You could try wearing a compression vest under a button-up, but you wouldn't be able to go in the water. For a beachy look, go with a vertical striped, checkered, or tropical print button-up shirt. Avoid white, and go for colors that won't contrast sharply with your swim trunks. White can make your upper body look broader, and a sharp contrast between your shirt and trunks will draw attention to your upper body. Vertical stripes and patterns are slimming and can draw the eye away from body shape. A button-up offers more structure than a tee, so it's less likely to cling to your chest. If anyone asks, you could say that you're wearing a shirt to protect your skin from the sun.

SUMMARY: Invest in a compression shirt or vest designed for gynecomastia. Conceal your chest with men's shapewear or performance apparel. Wear a swim shirt or rash guard. Cover up with a slimming striped or patterned button-up shirt.

In one sentence, describe what the following article is about: The variety of speaker builds suits individual speakers for different tasks. For casual music listening, a pair of bookshelf speakers would be more than enough. Those who desire a more intensive experience can upgrade to standing speakers. Surround sound systems are also a high-end option. Subwoofers are additional speakers that add depth to bass, which is low tone. They're good for movies and music with lower range such as rock and metal. For adding general depth to TV and movies, a soundbar or soundbase is an option. These take up less space, require less wiring, and can be combined with a subwoofer. Wireless and wall-mounted speakers benefit from portability and offer new sound angles in your room. For gaming, small specialized speakers usually offer enough sound. These are placed on a desktop near the computer and have magnetic shielding. Different surfaces affect sound quality. Hard, flat surfaces reflect sound and soft or varying surfaces absorb sound. Sound is also easier to hear in a small room. To get a sense of the room, stand in the center and clap. The less the sound carries, the more powerful the speakers you'll need. A small room such as a bedroom is fine with bookshelf speakers, but a large carpeted and furnished room benefits from bigger speakers. While bookshelf speakers will fit in a small bedroom, you wouldn't want to try to fit wide standing speakers in there. The sound can overwhelm a small room even if it has lots of absorbent furnishings. On the other hand, if you want a surround sound system for your television, the speakers need space away from the wall and surround you. Where you'll put the speakers matters. Speakers inside a cabinet, for instance, can get muffled, but so do speakers in room corners since the sound is distorted by the walls. Speakers benefit from being three to four feet away from the sound source. This helps them project sound into the room. Try to keep your speakers around ear-level. At that level, the sound will be clearest to you. It's very easy to fall into a price tag trap. You'll see bigger and better-looking speakers or a salesperson will refer you to them even though quality isn't completely related to price. A cheaper speaker may work better for you than a more expensive one. Stick to your budget as much as possible. Once you've decided on the type of speaker you need, go online or shop around in stores to compare prices. Determine how much you're willing to pay for the kind of speaker that seems right for you.
Summary:
Decide how you'll use the speakers. Consider your room's furnishings. Determine the space you have available. Consider your budget.
