Problem: Article: If you find yourself in an atmosphere where you can take off your tie before eating, then do it. When we spill on ourselves, it is usually right down our torsos where a tie hangs. It is all too easy to spill food on your tie and leave a stain, so avoid it if you can.
Summary: Remove your tie before you eat.

INPUT ARTICLE: Article: You can purchase one of these kits through a jewelry tool supplier. The kit will contain all of the materials that you’ll need along with a set of detailed instructions. Make sure to read the instructions carefully before beginning and conduct an inventory of the supplies before starting. These kits can be quite affordable, if ordered online. They start at around $30. Your kit will contain a number of needles that you’ll use for testing different types of gold. Look for a karat value marking on the side of the needle. Each needle will also have a colored gold sample at the tip. Use the yellow needle for yellow gold and the white needle for white gold. Turn the piece around until you find a less noticeable spot. Hold an engraving tool firmly in your hand and make a small divot in the metal. The goal is to expose the deeper layers of the metal. Since you are working with acid, it’s important to don thick, but fitted, gloves. Eye protection is also a good idea, just to be extra cautious. Avoid touching your face or your eyes while working with the acid. Select the proper needle for the gold type. Then, hold the needle tip directly over the notch. Push the plunger of the needle down until a single drop of acid drops into the divot. Look closely at the divot that you made earlier and where you just applied the acid. The acid will react with the metal and may turn a particular color. Generally, if the acid turns a green color, this indicates that the piece is not pure metal, but instead gold plated or another metal entirely. Since testing kits have different color indications, make sure to read the color guide carefully as you interpret the test results.

SUMMARY: Buy an acid testing kit for a more precise estimate of gold karat purity. Inspect the needles for karat value labels. Make a notch with an engraving tool. Put on protective gloves and goggles. Place a drop of acid on the notch. Read the results.

In one sentence, describe what the following article is about: Filleting should be done when you wish to serve only the finest cut of the fish, rather than cooking it whole. Start by cutting through the neck of the trout at the groove of the gills. Angle the blade of your knife so that you’re cutting toward the head rather than the body to preserve the meat. Always use a filleting knife or other sharp blade when preparing fish. This results in much neater, more economical cuts. Place the trout on its side with the belly facing away from you. Start a small cut on the top side of the backbone at the opening where you removed the head. Insert your filleting knife into this groove and run the knife down the length of the fish, staying just above the backbone. Finish by slicing through the section at the base of the tail. You now have a clean, meaty fillet. If you’re staying close enough to the backbone, you should be able to hear an audible clicking as you slice through the rib bones. Turn the trout over on its opposite side and repeat the filleting process. Start the cut at the head and slice smoothly along the upper edge of the backbone until the entire fillet has been cut away. Place each fillet skin side down and pick out each and every pin bone you find. Scrape along the flesh with your knife or pick up each fillet and flex it to expose bones that are lodged deep. Nothing ruins a fresh fish dinner like a mouthful of crunchy bones! It’s alright if you don’t get every last tiny bone—even professional chefs sometimes miss a few. Now that the trout has been filleted and deboned, you only need to make one more cut to remove the skin. Take hold of the fillet on the tail end and use your filleting knife to cut into the flesh at an angle until you reach the outer layer of skin. Run the knife edge along the bottom of the fillet while tugging the skin lightly in the opposite direction. The skin should come away clean. Repeat with the second fillet and you’re ready to grill, bake or fry! Again, while it is not necessary to remove the skin prior to cooking, it is commonly done when filleting fish and makes it easier to eat.
Summary: Remove the head of the trout. Cut the first fillet along the top of the backbone. Flip the trout over and cut the second fillet. Remove the pin bones. Get rid of the skin.

In one sentence, describe what the following article is about: Always tuck the shirt in and pair the shirt with an appropriate belt. For business casual, tie is optional.  White button-down shirts are the most formal and therefore the safest. Unlike pants, all manner of shirt colors are acceptable: Purple, pink, yellow, blue, and red. Choose shirts (and pants) in "formal" fabric: Cotton is king, and comes in many different flavors. Wool is acceptable, if itchy. Silk, rayon, and linen are frowned upon. Choose shirts in "formal patterns: Oxford, plaid, and poplin are a little less formal, but perfectly acceptable. Twill, herringbone, and broadcloth patterns are more formal and nice to use if sprucing up. Hawaiian and other irregular patterns are considered too casual. Jeans are not considered business casual.  Pleated pants and dark colors are more formal, conservative choices. If you want to be on the safe side, overdressing is less frowned upon than underdressing. Pants should extend to the top of your shoe, or slightly longer. Pants that don't reach down to your shoe are considered high-water pants; pants that fold and bunch up near the feet are considered too baggy. Avoid pants in loud colors such as red, yellow, and purple. Camouflage is not allowed, neither are white pants — they feel a little too informal for even business casual. Stick with black, brown, grey, khaki, dark blue and dark green pants. V-neck sweaters work best if wearing a a collar.  Turtlenecks can be worn in combination with a blazer for a sleek look and a little bit of novelty. If you want to wear a suit coat and still look business casual, dress it down with khakis instead of suit pants. Stick to black, brown, or grey shoes. Oxfords, lace-ups, and loafers are all standards. Avoid the following items, which, fortunately or unfortunately, don't fall under the category of business casual:  Sneakers, sandals, flip-flops or other open-toed shoes. Sports shirts, sweatshirts, sport team jackets, and athletic socks. Shorts and capris. Jeans. Very tight, and hence revealing, cuts of pants. No skinny-trousers allowed.
Summary:
Choose shirts that have collars, such as long-sleeve button down shirts. Wear pants styles such as khakis, dress pants, trousers and corduroy pants. Consider pairing your shirt with a sweater or sweater vest. Select formal leather shoes, and don’t forget the dress socks. Study the list of don'ts.
