INPUT ARTICLE: Article: Keep the bow facing vertically downward with the frog pointed up. Rest your hand on top in an open "handshake" position, with your palm resting lightly on top of the frog.  The "frog" refers to the enclosed mechanism that holds and tightens the bow hair. A "handshake" position simply refers to the sort of position you would hold your hand in if you were preparing to shake hands with someone. Note that this method is one of the most common ways to hold a German bow, but it is not the only way. If you want to explore different techniques, talk it over with a bass teacher or with a more experienced bassist. Gradually turn the bow sideways, drawing the frog further into the palm of your hand and pointing the bow inward toward your body.  The tip of your bent thumb should just barely touch the tip of your index finger, and both should rest lightly on top of the bow. Do not pinch the bow in between your thumb and index finger. They should only rest on top of the bow and should not grab onto it directly. Keep your hands relaxed and flexible to allow for movement, but not a loss of control, as you play. The wrist should bend slightly as you play downward in order to keep the bow straight across the strings. Similarly, the fingers will straighten a bit as you play, but be sure they do not hyperextend, which will reduce your control and make your transitions difficult on the backstroke.

SUMMARY: Hold the bow downward. Turn the bow until it touches your index finger. Maintain your hold while playing.

In one sentence, describe what the following article is about: You can create an alternative outdoor litter box for cats by using a new or old sandbox that is at least as big as a large litter box. Fill it with soft, fine-grained sand (this can be bought by the bag at hardware and home supply stores), which cats find especially attractive. With luck, cats will be drawn to the sandbox instead of your garden and use it much as they would a litterbox.  Make sure to scoop the sandbox regularly; if it gets too full, cats may return to using your yard. Keep children away from the cat sandbox, and make sure they understand not to play in it. If you want to keep cats out of your garden, but don’t mind them being in other areas of your yard, then try making a cat-friendly area. Cats will be attracted to areas covered by certain plants, and hopefully leave the rest of your yard alone. Create a small plot and grow one or more of the following non-toxic plants in it:  Catnip (Nepeta cataria) Catmint (Nepeta mussinii) Cat thyme (Teucrium marum) Valerian (Valeriana officinalis) Spider-plant (Chlorophytum comosum) If you have a bird feeder near your garden, move it to another area of your yard that is further away. Ideally, you should hang the bird feeder in an area that is too high for a cat to jump to. Otherwise, a bird that visits for a meal might be in more danger than your garden ever was.
Summary: Make a cat sandbox. Attract cats to a cat garden. Move your bird feeder.

Classic tabby cats tend to have blotchy patterns across the body, leading some people to colloquially refer to classic tabbies as "blotched tabbies". The stripes on a classic tabby cat tend to be wider and thicker than on other varieties of tabbies. Those thicker lines can contribute to the blotchy pattern that is characteristic of classic tabbies. The distinct tabby lines appear circular or swirling on classic tabbies. On some cats they may even resemble a bullseye pattern. Typical tabby cats have black stripes over an otherwise brown coat. Other color variations do occur, but these typically have the qualifying color added before the word tabby, such as a ginger or red tabby (shades of orange and white) or a blue tabby (gray and white).

One-sentence summary -- Look for blotchy patterns. Look for wide stripes. Observe swirling lines. Check the color.

INPUT ARTICLE: Article: Begin with a small circle with a cross-section for the ninja’s head.  Draw an oval at the end of the line made in step 2. Draw 2 lines connecting the ovals a little before the side’s end. Draw 2 vertically-elongated ovals from the oval at the bottom end for the ninja’s legs. The sketch will guide you to produce a smooth and neat outline. Trace the smaller details of the ninja to produce drawing effects for the clothes.    {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/1\/1c\/Draw-a-Ninja-Step-14Bullet1.jpg\/v4-460px-Draw-a-Ninja-Step-14Bullet1.jpg","bigUrl":"\/images\/thumb\/1\/1c\/Draw-a-Ninja-Step-14Bullet1.jpg\/aid3057224-v4-728px-Draw-a-Ninja-Step-14Bullet1.jpg","smallWidth":460,"smallHeight":345,"bigWidth":"728","bigHeight":"546","licensing":"<div class=\"mw-parser-output\"><p>License: <a rel=\"nofollow\" class=\"external text\" href=\"https:\/\/creativecommons.org\/licenses\/by-nc-sa\/3.0\/\">Creative Commons<\/a><br>\n<\/p><p><br \/>\n<\/p><\/div>"}

SUMMARY:
Using pencil, roughly sketch the guidelines for drawing a ninja. Draw an oval a little under the circle and draw a line from the circle through the oval and further; this will be for the backbone of a ninja’s body (for sketch purposes)  Draw two small circles at the upper left and upper right side of the oval. Draw two small vertically-elongated ovals from the 2 small circles at the upper oval for the ninja’s arms. Carefully trace with a pen the outline of your sketch. Erase the sketch. Color the drawing as you like!
