Problem: Article: Metallic is not a color, it is created by light reflection, so this article will use a multi-stop gradient (a gradient with more than two colors).  For gold it should contain a succession of lighter and darker shades of yellow, maybe also a bit of orange. For bronze, yellow with a shade of green (copper oxidation is green), For steel it should contains greys. The chrome is also greys but more reflective (more contrast, from almost black to almost white), silver is less reflective grey and so on.  The gear does not stay on air, so add a background, and use the same golden gradient (if using this example). For the sake of simplicity, you can use a different one, maybe darker. Note the usefulness of the drop shadow, without it it would be hard to set apart the gear from the background, now they are distinct objects.
Summary: Now we will make the gears "real", emulating a metallic surface, like gold (or call it bronze, the process is about the same). Define the color. Then take one wheel and apply the gradient to it. For a 3D look, add a drop shadow (duplicate, make it black, move a few pixels down and right, move it under the wheel, add a bit of blur and maybe decrease the opacity). Add some more gears (all your golden gears).

INPUT ARTICLE: Article: This size is usually easy to find, as it's the one used in most printers. It should be shaped like a really pointy triangle right now, with one edge the original length of the paper and one edge half the original width of the paper. The other edge should be the longest of the three and should be opposite the right angle of the triangle. Have either of the sides facing up. It doesn't matter which one because you will do the same steps to both sides.

SUMMARY: Start with a standard letter-sized piece of paper that measures 8 1/2 inches by 11 inches (A4, printer paper). Lay the paper airplane down on your work surface.

In one sentence, describe what the following article is about: As soon as you realize your house has fleas, immediately wash your pet's bedding in very hot water to kill all of the fleas and their eggs. Wash other items your pet has touched, such as cloth toys, pillows, and so on. It's likely that the fleas have spread beyond your pet's domain, so go ahead and wash everything else, too. You may need to wash your clothes, your bedding (if your pet sleeps with you), your couch cushions, and anything else where fleas could live. Using a heavy-duty vacuum, vacuum your carpet thoroughly. Take your time, and go over the entire area more than once. You can also vacuum your sofa, upholstered chairs, and rugs. Use the hose attachment to vacuum the cracks in your baseboards, too.  Vacuuming has been proven to kill fleas. It sucks up adult fleas as well as their eggs. After you vacuum, empty the vacuum bag. Otherwise, the fleas will hatch from their eggs and climb out of the vacuum to re-infest your home. Cover the entire carpet with a layer of baking soda. Go ahead and use up several boxes. Let the baking soda sit on the carpet for at least 4 hours or overnight, then vacuum it up. The baking soda dries out the eggs in the carpet, helping to kill the next round of fleas before they hatch.  You can use borax instead of baking soda to treat your carpets. Be sure to vacuum it thoroughly after the treatment. Salt is another cheap and effective flea killer. Use it the same way you'd use baking soda. This completely natural powder kills adult fleas (and other insects) by piercing their exoskeletons when they walk over it. Wear a mask as you sprinkle it in areas where you have seen adult fleas. Leave it for 24 hours, then vacuum it up. If your home is on the humid side, you're providing the perfect climate for fleas. You can make your house less hospitable by using a dehumidifier to make the air drier. You could also turn on the AC, your fans, or a heater, depending on the season. If you have fleas in your house, they're probably in your yard, too. They thrive in tall grass, which shades them from the hot sun and keeps their environment moist. Exposing them to the sun is the best way to kill them. Mow your lawn frequently so that the grass won't get tall enough to shelter the fleas. Sprinkle it in areas where you have seen adult fleas just as you would any carpet deodorizer. Leave it for 24 hours, then vacuum it up thoroughly. This method will kill a full blown infestation in just days.
Summary: Wash your pet's bedding in hot water. Wash your sheets and other linens. Vacuum the carpet and upholstered furniture. Treat your carpet with baking soda. Sprinkle diatomaceous earth around your rooms. Use a dehumidifier. Keep your lawn short. Use borax.

Rather than cutting them into slices, you might decide to leave them in a larger size to give them more of a presence in the dish you’re cooking. In this case, you can slice the whole mushroom down the middle once to half it and call it a day. If you need it to be smaller still, cutting the halves in half will give you nice chunky quarters. Use mushroom halves or quarters in more substantial side dishes like bourbon mushrooms or vegetable medleys. Once your cutting board is covered with mushroom quarters or slices, you can proceed to reduce them to a more manageable size by cutting them widthwise, then rotating them 90 degrees and slicing them again. Chopped mushrooms are the perfect size to throw in a pot of soup or a hearty casserole.  You also have the option of stopping after a single cut if you prefer bigger pieces. Keep in mind that mushrooms shrink quite a bit as they cook, so avoid chopping them too small if you don’t want them to disappear completely. Turn the mushrooms 1 more time and cut them into even smaller pieces. When fine-dicing or mincing, keep the blade of the knife in contact with the cutting board and raise and lower the rear edge of the blade repeatedly in a lever action. Continue cutting the mushrooms until they’re the desired size.  You may have to dig out the bulkier pieces and tackle them individually, as the mushrooms’ irregular shape will mean that some will be bigger than others. Stuff diced mushrooms into homemade egg rolls or samosas, or sprinkle them over a fresh garden salad.

One-sentence summary -- Cut the mushrooms into halves or quarters. Turn the mushrooms for a coarse chop. Dice or mince the chopped mushrooms. Finished.

In one sentence, describe what the following article is about: Using a plugging chisel and sledge, chip the cinder block into pieces. Remove the block in chunks as you free each piece from the surrounding mortar. Chip out the mortar, then brush away any additional dust or debris before putting the new block in place. Wear safety goggles while chipping the block out to prevent eye injuries. Purchase a bag of pre-mixed mortar and pour it into a bucket or wheelbarrow. Add the required amount of water and stir it with a shovel until it has an even consistency. Let the mix sit for 3-5 minutes before applying it to the wall to let the mortar absorb moisture so it will stick to the cinder blocks better. Using a trowel, add a 1 inch (2.5 cm) thick layer of mortar around the top, bottom, and sides of the empty space in the wall. Keep the layer as even as possible to avoid creating tight or loose sections in the wall. Slip the new cinder block in place with a trowel, then scrape away any excess mortar. Let the mortar dry for 12-24 hours, depending on the mix. When the mortar is dry and stable, it should turn a light gray color.
Summary:
Chip out the old cinder block and mortar. Mix the mortar. Apply mortar around the edges of the cavity. Set the new block in place.
