Problem: Write an article based on this summary: Practice rewriting your favorite raps. Learn poetic techniques to up your game. Use specific imagery in your lyrics. Work on the flow, or delivery, of your lines so that they work together to tell your story. Read the great rappers for inspiration.

Answer: This is one of the best ways to learn rapping technique. Take your favorite songs and learn them forwards and backward. Then rewrite the rap, using the same rhyme scheme but with your own verses. This is how mixtapes first became popular, with rappers like Curren$y and 50 Cent taking popular songs, flipping them, and making them their own. Even if you never share the song, this is a great way to learn rap techniques naturally. Rap is poetry -- using words, sounds, and rhymes to create beautiful art and ideas. As such, it is no surprise that the best rappers have taken inspiration from the best poets. Eminem, for example, famously used Shakespearean meter and rhyme in many of his famous songs. Other examples include: Alliteration/Assonance: Words with similar sounds that are placed close together, like "Two tip-top teachers" or "apple attitudes." Listen to Joey Bada$$'s "Waves" for a great example. Simile/Metaphor: Closely connected, this is when writers compare two objects that aren't usually alike to make a point. For example -- "I put the metal to his chest like Robocop" works on multiple levels, bullets are made of metal, Robocop's chest is covered in metal armor, and the biggest target when shooting someone is their chest. This is a much more poetic way to imply "I might shoot him." Refrain: A line that is repeated at various points for emphasis. The more you hear the line, the more it changes, evolves, and gains power. For a master class in how to use a refrain, see Kendrick Lamar's "The Blacker the Berry." Anaphora: When the first half of a line repeats, but the rest of the line changes, like in Eminem's "If I Had" where ever line begins with "Tired of...." This is a great way to show how difficult, constant, or trying something may be, or overwhelm the listener intentionally. Great imagery puts visuals behind the listeners' eyes, engaging multiple senses to create complex, engaging raps. The best rappers all conjure images up in your mind, telling stories and making their lyrics come alive. To do this, focus on being specific-- use adjectives and adverbs to make the images your own. This doesn't have to be purely visual imagery. Action Bronson uses foods and scents in his raps to give them an entirely new dimension. The kings of imagery, Andre 3000, Ghostface Killah, Eminem, etc. are often those rappers that gain the greatest followings. Good lines become great lines with good flow. Flow is how you deliver the words in relation to the beat. Are you slow, holding back, or are you attacking the beat with speed and intensity. Do you waver up and down, picking up and slowing down depending on the line? Flow takes practice and patience, so put a beat on and practice. You don't have to have the same flow throughout the whole song. Nas's incredibly "NY State of Mind" flows like a great jazz solo -- stopping, starting, pausing and pushing forward around the incredible rhymes. Much like a burgeoning writer needs to study the best poets, a growing rapper needs to read to the best. Reading a rap lets you see it on the page, much like the rapper when they wrote the lyrics. This will help you comprehend rhyme schemes and little tricks. Sites like RapGenius, for example, even have annotated lyrics that explain metaphors, rhymes, and references. Listen to what you enjoy, but a small selection of essential verses (in addition to the other songs referenced in the article) to start with includes: AZ's, first verse on "Life's a B---", off of Nas's album Illmatic. Notorious B.I.G, "Notorious Thugs." Black Thought, "75 Bars (Black's Reconstruction). Rakim on "As the Rhyme Goes On," on Paid in Full. Kendrick Lamar, "Sing About Me, I'm Dying of Thirst." Lupe Fiasco, "Murals." Eminem, "Lose Yourself."

Problem: Write an article based on this summary: Put on safety goggles and ear protection. Saw completely through the luggage rivet using a hacksaw. Place the old bearings into the new luggage wheel. Insert the new wheel into the luggage. Tighten the nut and test the new wheel.

Answer: Riveted luggage wheels require a hacksaw to replace. Before handling a hacksaw, put on a pair of safety goggles to protect your eyes. If you have sensitive ears, put in ear plugs or a pair of noise-canceling headphones. Of the 2 types, riveted luggage wheels are more difficult to replace than screwed luggage wheels. Slice through the end of the luggage rivet with your hacksaw. Use a screwdriver or your hands to pull apart the old rivet and the bearings or washers holding the wheel in place. Remove the old luggage wheel from the wheel well as well. Unlike the bearings or washers, however, you can discard the wheel. Set the bearing and washers aside for use while installing the new wheel. Put 1 bearing on each side of the luggage wheel. These will help keep the wheel in place as you install it into the wheel well. Put the replacement wheel into the wheel well, then slide a 2in (5.1cm) screw through the luggage wheel and bearing. Place a washer on both sides of the screw to secure it in place. Screw a nut into the end of the screw to finish securing the new wheel. Test its fit by moving the luggage back and forth over a flat area. If the luggage glides smoothly, it is the right fit for your luggage. If the luggage is too wobbly, try tightening the nut more. Your wheel may be the wrong size, however, if the wheel cannot move or still feels wobbly after tightening it.

Problem: Write an article based on this summary: Bring a clear, sealable plastic bag for your toiletries. Take your medication along. Pack your toothbrush and toothpaste. Take along some hand sanitizer. Consider bringing lip balm and moisturizer. Ward off bad odors with deodorant. Don't forget your feminine hygiene products.

Answer:
Liquids and gels in your carry-on bag are limited to 100ml (3.4 oz) and need to be sealed in a clear plastic bag before flying. Pack your toiletries into this plastic bag before going to the airport to avoid delays at the security check. All containers of liquids, aerosols, or gels must go in this bag. For flights to the U.S. it helps to know the 3-1-1 rule. This rule means that all liquid containers of 3.4 ounces or less ('3') must be stored in a single, clear, sealable bag ('1') which is limited to 1 per person ('1'). Medications are exempt from this restriction. Store this plastic bag in an outer pocket, so that it may be easily removed from your carry-on bag at the security checkpoint. If you have any essential medication that must travel with you, make sure you bring it along. Most medication is subject to a screening at the security checkpoint, so keeping it in its original packaging will ensure you are not delayed in your travels. While most airlines will provide you with a small toothbrush and toothpaste set for your long-haul flight, it is always best to pack your own. Being able to brush your teeth will greatly enhance your comfort on the flight. If you like to talk to your traveling companions when you fly, having fresh breath will help your confidence and make the conversation flow more smoothly. Visiting the restroom on a plane can feel pretty gross sometimes. Packing a small container of hand sanitizer to use after trips to the restroom will make you feel much cleaner. The air in airplanes tends to be drier than average. If your skin tends to dry out, bring along some moisturizer and use it regularly. To stop your lips from drying out and cracking, use a gentle lip balm. Unfortunately, there's no escaping body odor on a long flight. With no access to a shower on the plane, you're likely to feel quite smelly by the end of your trip. Deodorant is the next best thing, so make sure to bring some along. Having easy access to your feminine hygiene products can take a lot of the stress out of long-haul flights. It sucks being caught unaware, so pack these just in case.
