Article: But to simplify calculations, the U.S. military calculates them as 1-6283 of a circle (previously 1-6400 on older scopes). Russian-based scopes are set to 1-6,000 of a circle. This means there is up to a 3% error in distance calculations.
Question: What is a summary of what this article is about?
A Mil is 1-6,175 of a circle. Mil distances on rear-plane cross hairs on a variable-power scope usually are only accurate at the highest power.
Article: Unless you practice this a great deal, you will find it hard to accomplish and the air of your moving hand gives the mosquito plenty of warning, and can even blow it out of your grasp. The swatter, usually made of a thicker metal or plastic, is mounted on the end of a springy wire, dramatically increasing your chances of hitting a stationary mosquito by increasing the momentum of the swat. You can also use your hand in a similar flipping motion. Using two hands is more effective than one, as the air coming from each hand will blow the mosquito into the opposing palm. There's an urban legend that says you flex your muscle or stretch your skin tight as a mosquito bites you, its proboscis will get stuck in your skin and it will drink your blood until it explodes. There isn't any scientific research to support this claim. Even if you can get this method to work, you'll still be left with an especially big bite and you'll still be putting yourself at risk for malaria, West Nile virus, etc. If you're trying to avoid mosquito bites, why kill the mosquito by  letting it bite you? If the above steps aren't working or the thought of killing a mosquito makes you feel guilty, you can try catching a mosquito alive, then releasing it outside of your home or camp. Slowly place a cup (preferably made of a hard material) over the mosquito and then slide some paper underneath this cup. This gives you control over the mosquito and can provide you with a more pacifistic approach, instead of just killing the mosquito. Carefully hold the paper over the cup's bottom as you relocate the mosquito to a more appropriate habitat.
Question: What is a summary of what this article is about?
Grab the mosquito out of the air. Use a mosquito swatter. Use a double-handed clap. Don't try to trap the mosquito while it bites you. Trap the mosquito in a cup.
Article: If something flames up in the oven or the nuke machine, stay calm. Turn off the device, close the door, and watch it closely. Closing it off and eliminating the heat source should make small fires die down quickly. Get your fire extinguisher and watch it closely. If the fire doesn't die down, open the door very carefully and spray it with the extinguisher to put the fire out. If you have any trouble whatsoever, call the fire department immediately. If you've flamed up something in the skillet, use the lid (or a lid of larger size) to clap on quickly and smother it. This is the quickest and most effective way of stopping the fire. Consider moving the pan outside if it's creating a lot of smelly smoke. Rinse it out with the hose when it's cooled down to keep the mess from stinking up your kitchen. Make sure you put on a heating pad or oven mitt first before trying to grab the handle. If you're frying bacon and the grease catches on fire, it can be a tricky proposition. You can use the lid method, or use a slightly damp towel to smother the fire, but usually the safest and quickest (though not cleanest) method is to sprinkle a liberal amount of baking soda or salt onto the grease to quickly absorb it and eliminate the fire at the source.  You should also feel free to use a fire extinguisher on grease fires. It works particularly well. Stand at a safe distance from the grease and activate the extinguisher. Avoid using water or flour on grease fires. Flour can ignite, making the fire worse, and--since water doesn't mix with oil--water can cause the oil to spray elsewhere, throwing flaming oil onto other nearby surfaces. It's extremely dangerous to try to control or extinguish electrical fires yourself because they're very difficult to anticipate and trace the source of. Get out of your home immediately, getting everyone to safety, and call the fire department.
Question: What is a summary of what this article is about?
Cut off the oxygen of microwave or oven fires. Put a lid on it. Use baking soda or salt on grease fires. Always call the fire department immediately in the event of electrical fires.
