INPUT ARTICLE: Article: Once you and the other party have finalized all of the detailed contract provisions, one of you should prepare the final version of the contract. Whether you prepare this document or receive it from the other party, take time to read through the entire contract and make sure it correctly reflects the terms to which you agreed. If the contract has gone through several rounds of revisions and redlines, make sure the final version has all changes accepted and that all comments are cleared from the document. While not every state requires the parties' signatures for a contract to be legally enforceable, it is always best to have all parties sign. The signature reflects each party's agreement to the terms of the contract. If one party sues for breach of contract, it is much easier to prove the existence of the agreement if the party can show the court the signed contract. The correct party must sign the contract. If a business is one of the parties to the contract, make sure the person signing on behalf of the company is authorized to do so. Electronic, or digital, signatures may be permissible in place of written signatures. Check with the other party and your state laws to determine whether this is permissible for your contract. It may not be necessary for both parties to sign the same document. As long as the parties sign identical documents, the two signature pages may be combined to create a single document. Once both parties have signed the contract, make a few copies of the signed document. Keep a copy in a safe location, and consider making a digital copy to store on your computer. The original contract also should be kept in a secure location, such as a safe deposit box, fireproof safe, or a lawyer's office. Contracts often include information regarding when the contract terms expire, and whether and how the contract can be renewed. Keep track of these dates by putting them on your calendar, so that you can take action to terminate or renew the contract as you desire.

SUMMARY: Prepare a clean version of contract for signature. Sign the contract. Make copies of the signed contract. Keep track of expiration and renewal dates contained in the contract.

In one sentence, describe what the following article is about: Put away notebooks, papers, and any other clutter that might pose a fire hazard. Avoid using a Bunsen burner below a shelf or other overhead equipment. In addition to wearing protective goggles and gloves, make sure your wardrobe is free of potential fire hazards. Tie back long hair, tuck in or remove loose clothing, and take off dangling jewelry. Remember to always wear closed-toed shoes in the lab. Consider wearing a lab coat to cover any loose clothing. Before lighting the burner, know where to exit in case of an emergency, find the emergency gas switch, and locate the fire alarm. Note safety equipment, such as fire extinguishers and dry powder flame retardants. Hold the Bunsen burner only by the base or by the collar at the bottom of the barrel. After the burner is lit, the barrel itself will be too hot to handle. To reinforce safety habits, avoid touching the barrel even if the burner isn't in use. Keep your eye on it at all times, and never leave the laboratory while it's lit. If you are working on something for a moment that does not require the flame, turn it down to the coolest yellow flame (known as a safety flame).
Summary: Use a Bunsen burner in a clean, uncluttered area. Wear safety gear and tie back loose hair or clothing. Locate safety equipment, the fire alarm, and emergency exits. Handle the burner by its base. Never leave a lit Bunsen burner unattended.

Foods and beverages take in the heat created by a microwave, while metallic items cause this heat to bounce around. This may start a fire and/or damage the inner-workings of your appliance, leaving you with far worse problems than a bad smell. Don't put any kind of metal into the microwaveboth aluminum foil and metal utensils can damage your appliance.

One-sentence summary -- Avoid heating anything made of metal in the microwave.

Q: Pour 1 teaspoon (5 ml) of vegetable oil into a large skillet or wok and turn the heat to medium. Once the oil is hot and shimmers, stir in 1/2 cup (75 g) of chopped onion. Stir and cook the onion until it becomes soft and almost clear. You can leave the onion in large chunks or dice it finely according to your preferences. Add 3 tablespoons (24 g) of ground crayfish to the sauteed onions and stir until they're combined. Cook the mixture over medium heat until the crayfish is fragrant. If you can't find ground crayfish, you can leave it out but the rice won't be as colorful. Add 1 1/2 cups (230 g) of diced mixed vegetables into the skillet and stir in 1/2 teaspoon (0.5 g) of ground pepper, 1 teaspoon (2 g) of Nigerian or Jamaican curry powder, and 1 to 3 stock cubes (such as Maggi or Knorr). You can use frozen mixed vegetables and add them to the skillet while they're still frozen. If you prefer, chop and dice your own mixed vegetables. Try carrots, corn, green beans, and peas. Stir and cook the vegetable mixture over medium heat until the vegetables are heated throughout. If you used frozen vegetables, this will take closer to 5 minutes. Avoid overcooking the vegetables or they'll lose their shape and their color will dull. If the vegetables stick to the skillet, pour in another 1 teaspoon (5 ml) of cooking oil.
A: Saute the onions for 7 to 8 minutes. Stir in ground crayfish and cook the mixture for 1 minute. Stir in vegetables and seasonings. Fry the vegetables in the seasoning for 2 to 5 minutes.

INPUT ARTICLE: Article: The air around you is pressing against you and every other object, with a pressure as high as 101 kPa (14.7 pounds per square inch) when you're at sea level. This would normally be enough to crush a can by itself, or even a person! This doesn't happen because the air inside the soda can (or the material inside your body) is pushing outward with equal pressure, and because the air pressure "cancels itself out" by pushing at us from every direction equally. When the water in the can boils, you can see the water start to escape as little droplets in the air, or steam. Some of the air in the can gets pushed out when this happens, to make room for the expanding cloud of water droplets. Despite the can losing some of the air inside it, it doesn't get crushed yet, because the water vapor that took the place of the air is pushing from the inside instead. In general, the more you heat a liquid or a gas, the more it expands. If it is an enclosed container so it can't keep expanding, it exerts more pressure. This is known as Gay-Lussac's Law. When the can is turned upside down in the ice water, the situation changes in two ways. First, the can is no longer open to the air, since water is blocking the opening. Second, the water vapor inside the can rapidly cools down again. The water vapor once again shrinks down to its original volume, the tiny amount of water at the bottom of the can. Suddenly, most of the space inside the can has nothing in it at all not even air! The air that's been pressing from the outside of the can this whole time suddenly has nothing on the other side to resist it, so it crushes the can inward. Space that has nothing in it is called a vacuum. The appearance of a vacuum, or empty space, inside the can has one other effect besides causing the can to be crushed. Watch the can carefully as you lower it into the water, and again as you lift it out. You might notice a small amount of water getting sucked up into the can, then trickling out again. This is because the water pressure is pushing against the opening of the can, but only hard enough to fill a little of the can before the aluminum is crushed.

SUMMARY:
Learn about air pressure. Figure out what happens when you heat the can of water. Understand how the can gets crushed. Watch the can closely to discover one more effect of the experiment.
