In one sentence, describe what the following article is about: Hold a household magnet near the brass piece, and see if it is magnetically attracted to the brass.  If the magnet doesn't magnetically cling to the object, it's brass. If the magnet does magnetically cling to the object, it's likely that the “brass” piece is really a piece of iron or steel, covered with a brass coating. Some brass objects are not meant to be bright, and therefore, any efforts to clean the piece might actually diminish its worth. If you are unsure of what your next steps should be in cleaning a brass piece, talk to a brass expert and discuss your cleaning options.  Sometimes patina (the turquoise coloring that forms on brass and copper) can add a unique look to a piece of brass, and should be left alone. Patina is used to evaluate many aspects of a piece of brass. For example, patina can be used to determine the age of a piece of brass, its current condition, and its potential value. Any removal or alteration of patina on a brass piece can significantly affect its worth. On modern brass pieces, an outer coating of lacquer serves as a layer of protection against oxidation. But, older, antique pieces of brass typically don't have a lacquered coating. You can assess if a brass piece is lacquered by looking at its surface: it will have a clear finish covering the entire piece. Brass covered with lacquer will usually only tarnish if there is a crack in the lacquer coating.  Lacquered brass is fairly easy to clean; all you really need is some soapy water. However, you might want to consider removing the lacquering if tarnish has formed underneath the lacquer finish. If you are still having trouble figuring out if your brass piece has a lacquered finish, remember that lacquered brass usually has more of a yellow shading.
Summary: Determine if the piece you want to clean is actually brass. Determine if the piece you want to clean should be cleaned. Determine if the brass piece is lacquered.

In one sentence, describe what the following article is about: There are ways you can reduce government's interference in your checkbook at tax time!   Contribute money to a 401K account or IRA. Don't pay off your student loans. You will be able to deduct the student loan interest.  Buy a house, contribute to charity, take college classes, save your receipts, and have your taxes done by a professional who knows tax laws better than you do. In the most simplistic sense, living off the grid can mean not connecting into government provided electricity. Survive on your own.    Solar energy or your own generator can provide power instead. Try not to use light at night. Perhaps use candles. Make your own food by gardening. Settle on land that offers available water so you don’t need to depend on government for water. In urban areas especially, surveillance cameras and police devices are able to track your movements through your vehicle’s license plate. Get rid of the GPS device in your car.   Instead, walk or ride a bicycle when you can. In addition, avoid toll roads, toll bridges and HOV lanes because they are monitored with surveillance cameras. Take a cab and pay cash. Rental car information can be tracked. Avoid parking in garages and lots with surveillance cameras and, if you use public transit, buy the ticket from the machine instead of using a new card payment system. Avoid driving on interstate highways. Don’t take the same exact route every time you go to the store or to work. Mix up your routine.  Don’t get deliveries to your home because that will create a record. Use maps instead of GPS. Buy a shredder to shred all paper documents when you are done with them. Get a post office box so that purchases can’t be traced back to your home. This will make it harder for the government to trace you, not just data mining sites. Ordering streaming videos from a service like Netflix can put you on the grid. Instead, order DVDs. Get a game console with single player games so you don't need Internet.  Don’t order books from the library with a library card as these can also be traced. If you really want to disappear, get rid of all trophies and old personal items. . Earn so little as to be exempt from paying taxes (and consider freeganism to survive). Squat for somewhere to live.   Alternatively, Live in the Wilderness or Survive in the Woods. Make sure you are paid in cash, or cryptocurrency like bitcoin. Settle in a mid-sized city in a place that is not overly cold. Bigger cities have too many cameras and smaller towns won’t let you disappear enough.
Summary: Pay less money in taxes to the government. Use your own power. Don’t drive much. Vary your routine. Watch your reading and viewing habits. Live for free

In one sentence, describe what the following article is about: Get used to moving your whole hand fluidly across the guitar to master the above riff. Use your index finger to fret as much as possible instead of switching fingers -- you'll need your ring and pinkie free to make chords later on. Listen closely and you can hear Jack White sliding around the guitar. It is most pronounced right before he launches into the riff, sliding into that 7th fret note. If you were to play the song with just an acoustic guitar, for example, you'd need to know the chord melodies. But these chords could be used for any cover or version -- look at Marcus Collins version, which uses rhythm guitar in the verse where the original has none. To play chord melodies, simply play the following chords -- each chord times up to the same note in the bass riff above.  E (7th fret, 5th string) G (5th fret, 4th string) D (5th fret, 5th string) C (3rd fret, 5th string B (2nd fret, 5th string These can be played as straight chords or powerchords. To get a real "White Stripes" sound from your guitar, your amp needs to be adjusted a little. Don't worry, you're not opening anything up, just change the settings a little. You'll need quite a bit of gain, try turning that up to 8. To even that out, keep your treble all the way up to 7 or 8 too. Keeps the mids at 5 while the bass should be pumped up to 8. If your amp has an effect called "Presence", turn that up to 8 too.
Summary:
Use your index finger, sliding it around the neck, as much as possible. Learn the implied guitar chords for the verse. Fix up your amp.
