Problem: Write an article based on this summary: Talk to your friends and neighbors. Contact your elected officials. Join the divestment movement.

Answer: Educate them on the benefits of recycling, conserving energy, and eco-friendly transportation options. Appeal to their concerns as parents, older siblings, or aunts/uncles. If they don't consider themselves environmentalists, ask them to take these measures so that the children in their lives will have a decent future. A great way to spread information is by going door-to-door. If you want to hand out pamphlets, make sure that you use recycled paper. Consider hosting a meeting or presentation at a community center so that you can educate a bunch of people at once. It only takes two minutes to send an email to your state and national representatives, but why stop there? Attend town hall, city council, and school board meetings to voice your concerns in public. Ask your senator/representative/MP why they voted to expand oil drilling. Tell your city council you'd like to see a bus or light rail system. Ask your school board to adopt an anti-idling policy on school grounds. If you are still a kid, consider talking to your school principal or student council. They may find solutions for saving energy and paper. Search online for organizations urging corporations to divest (remove their money) from pipelines and other fossil-fuel projects. This includes banks, credit card companies, and boards overseeing pensions. For example, if your bank or credit card company funds these projects, tell them you will do business with more responsible companies if they don't divest.

Problem: Write an article based on this summary: Dig out any grass and topsoil. Level the surface of the driveway. Compact the dirt. Lay down a weed barrier. Place your border.

Answer: Using a shovel or hiring someone with a backhoe, remove the top layers of grass and dirt from the marked-off driveway area. You might want to use a tiller to loosen up the soil and make it easier to dig out. The amount of soil you remove depends on how many layers of soil you are planning. You should dig 4-6 inches of soil for every layer of rocks you plan to put down. This doesn't have to be perfect since it will be covered by rocks, but your driveway surface should be pretty levelany areas that are deeper than other areas may lead to water pooling and cause mud puddles that have to be filled in with more gravel later. Use a mechanical compactor, have someone drive over the area with a bulldozer, or drive over the area repeatedly with a heavy vehicle such as a large truck. If you want to prevent grass and weeds from growing through your driveway, you may want to lay a weed barrier underneath your rocks. Weed barrier is a woven landscaping cloth that allows water to pass through it but does not allow weeds to grow through it, and it is available at most landscaping and home improvement stores. Weed barrier usually comes on a roll. You should be able to lay the roll down at one end of your driveway and unroll it until you have reached the other end of your driveway. Most weed barrier rolls are 4 feet wide, so you may need to get several rolls. Be sure the amount of weed barrier you buy matches or exceeds the square footage (length times width) of your driveway. If you are using landscaping timber or bricks to edge your driveway, you may want to place them before the gravel is delivered so that they can hold the rocks in place. If you do not want a border, you can skip this step.

Problem: Write an article based on this summary: Spray cats with a hose. Use a motion-activated sprinkler. Use an ultrasonic device to deter cats. Get a dog.

Answer: If you are watchful, you may be able to simply spray cats with a water hose whenever they are trying to use your garden. Cats can be trained, so if you are persistent, this may eventually be enough to permanently drive them away. Be gentle when you are spraying cats with a water hose. Most cats do not like water, so a quick, gentle squirt is usually enoughthere is no need for high-powered nozzles, or to thoroughly soak the intruding cats. Motion-activated sprinklers are available from home supply stores. When a cat walks by, the motion triggers the sprinkler, which sprays a burst of water. Most cats do not like getting wet, so this can often be an effective deterrent. Use motion-activated sprinklers to create a border around your garden. These sprinklers can be installed either permanently or temporarily, depending on your preference and needs. These emit a high-frequency sound that cats detest, but which humans cannot hear. These devices are motion-activated, so that when a cat walks by, it is startled by the high-frequency sound and should leave the area. Look for ultrasonic devices at a pet supply store, and use them to create a barrier around your garden. Cats will not linger in areas they do not feel are safe from predators. For this reason, a dog that chases cats can effectively keep them out of your garden.

Problem: Write an article based on this summary: Select the type of material for the dizi's body. Choose the size of your flute. Determine the style of ends for the dizi. Carefully measure the outside diameter of your flute body.

Answer:
Traditional dizis are made of bamboo, while historically, dizis and other flutes have been made from bone, jade or other stone, or pottery. Be sure to take into account being able to acquire and prepare the materials. Choose a piece of material that is about " to 1" in diameter. Bamboo is the ideal material for a homemade dizi, as it is easy to acquire and easy to manufacture into a dizi. It is also lighter and will likely be easier to play, which is useful if you are a beginning player. Bamboo can come from a regular bamboo plant with any extraneous leaves removed, or you can repurpose another bamboo object, such as an old bamboo fishing rod. There are different strains of bamboo that can be used; purple bamboo is typically used in the northern regions of China, while white bamboo is typically used in southern China. The size of the flute will determine the musical key in which it plays. Flutes are typically available in the following keys (from longest to shortest): F, G, G#, A, A#, B, C, C#, D, D#, E, F and F#. A good length is approximately 18-20" long. Longer flutes may have an additional finger hole (the larger dizi has this), and they play lower octaves. Small flutes with higher octaves are smaller than 16", while longer flutes are ideally 24-26" long. Choose ringed ends, capped ends, or no ends for the dizi. These will determine how long-lasting your flute is, as well as how susceptible to cracking or molding it may become. The materials for the capped or ringed ends, called ferrules, can be made of brass, bone, plastic or wood. Ringed ends: Some flutes have a brass ring around the end. This helps the flute (especially those made of bamboo or other wood) from cracking. Moisture can get underneath the ring, however, and cause molding. These can also be installed on a flute that did not previously have a ring in order to stop a crack from getting bigger. Capped ends: These ends are often made from plastic, cow bone or horn. Flutes with capped ends typically make brighter tones. Moisture can get underneath the cap, however, and cause molding. No ends: You do not need to have any rings or caps on the end of your flute. Instead, you can paint the ends to add decoration, or you can leave them bare. However, bamboo flutes especially may be susceptible to cracking more easily than flutes with ringed or capped ends. Find the correct size of plastic or metal ring or cap to fit this diameter at a hardware store. If you are not using any ends, you can also opt to wrap string around the dizi to prevent cracking.
