Problem: Article: Use a portable air monitor to test the air outside and make sure that the levels are normal before venturing there. You also need to make sure that any fires or flooding caused by the comet have subsided. Acid rain is also a potential result from massive fires putting pyrotoxins into the air, which would make going outside deadly. Have a reason to go outside, like being out of food or supplies, or hearing about other groups of people who survived and wanting to join them. Whatever the comet did not destroy can be salvaged for use, like food, batteries, water, or anything else you'd find useful from abandoned stores and houses. Make sure that you are not stealing from anyone and that the goods have been abandoned by their previous owners to avoid confrontations. There is a chance that the location you try to scavenge in has already been sorted through, depending on the length of time you've been hiding out. If you've managed to survive the comet impact, there's a good likelihood that others have as well. Hunger breeds violence and people will want to your steal supplies in order to survive. Always try to resolve things peacefully, not violently. There may be other groups willing to share resources as long as you share yours. Always approach people cautiously, but not in a hostile manner. Non-perishable and canned food won't sustain you forever, so you will have to get used to hunting and gathering your own food. Designate different people based on their strengths to search for food. Moving near the equator will be warmer and if the dirt is fertile, this will allow you to begin to grow food for consumption. Having more people in your group will allow you to search for food more effectively. Moving near a large body of water will allow you to fish. Use survival guides to determine what foliage is good to eat and what is poisonous. A popular vote is a direct democracy and would work so that everyone had a voice in matters that affect the group. While having a final decision maker or leader is conventionally how smaller groups tend to act, having everyone's voice be heard will hopefully ensure less fighting in your group. As your group gets larger, the governance system becomes more critical. Make sure to hold everyone to the same standards.
Summary: Make sure the environment is safe before going out into the world. Scavenge for additional supplies and food. Prepare to defend yourself from desperate survivors. Move to a fertile place near the equator and plant vegetable seeds. Create a governance system for your new society.

Problem: Article: Fill the bottle slowly, so that the soap doesn't bubble up and run over the top. It's best to use lukewarm distilled water rather than tap water, since your tap water may contain minerals and other impurities. You can find various brands of dishwashing detergents at your local grocery store or pharmacy. Before applying dishwashing soap to your plasma screen, read your TV's warranty. Make sure that it won't be voided if you clean the screen with soap. Aim the liquid spray away from your TV so you don't risk spraying the soap solution directly onto your plasma screen. Then, squeeze the trigger 2-3 times to lightly dampen your microfiber cloth. If you spray too much liquid into the cloth, you can wring it out over a sink to remove excess moisture. Put your index finger in the cloth under the damp region. Press your finger lightly against the spot on your screen. Move your finger in a circular motion to wipe the dishwashing soap solution onto the stubborn stain. After a few wipes, the stain should come off. If the screen is still dirty, try adding another 2-3 sprays of soap solution onto your microfiber cloth. And wipe the screen again. Press lightly on the screen as you wipe it clean. Don't apply a lot of pressure, or you may damage the plasma. Once you've spot-cleaned the screen and have removed the stubborn stains, use 1 more microfiber cloth to dry the spots you cleaned. This will prevent new bits of airborne dust from sticking to the screen. If you find that the screen is still slightly wet and soapy, you may need to slightly dampen a microfiber cloth with distilled water. Use the cloth to wipe the soapy residue off the screen.
Summary: Fill a spray bottle with water and 2-3 drops of dishwashing detergent. Spray 2-3 squirts of the liquid onto a microfiber cloth. Use 1 finger to wipe the stained spot on your plasma screen. Wipe the screen dry with a clean microfiber cloth.

Problem: Article: An apple is just an apple, right? Not when you've got a Fuji, a Golden Delicious, a Baldwin, and a Rome to choose between. There are literally hundreds of varieties of eating apples, cultivated for different properties of flavor and texture. While some are more available than others, depending on where you live, learning some basics will help you get the right kind of apple for your tastes. If you like sweet apples, Fuji, Jazz, Golden Delicious, and McIntosh are all creamy and sweet choices. If you like crunchy apples, Pink Lady, Honey Crisp, and Gala will give you the tooth you're looking for. If you want to bake with your apples, or like tart apples, Granny Smiths, Braeburns, and Jona golds are all solid choices. At the store, or if you're really fortunate in the orchard, check to make sure that apples are firm to the touch and fragrant. A ripe apple should feel firm and should smell like an apple at the stem and at the blossom end. Some apples, like the Macintosh or the Jonathan, will feel slightly softer to the touch, because the flesh is somewhat mealier. That's perfectly fine. If they smell ripe, they are good to eat. Look for bruising, discolouration, and signs of worm infestation in your apples. Apples with brown soft spots or dark holes that look burrowed into the flesh should be avoided. Little superficial dark dots on the skin of the apple are fine to eat, however. In general, you're looking for signs of over-ripeness, not under-ripeness. All apples you get at the store should be ripe enough to eat right away. You're just trying to make sure you don't get any over-aged apples. Apples are harvested at their peak of ripeness, so they're perfectly fine to eat right away. You can keep them on the counter for a day or two. If you don't want to eat your apples right away, keep them in the refrigerator in a paper bag. Good either way. Saying that one bad apple spoils the bunch is more than just a tidy phrase. Apples produce ethylene as they ripen, which promotes ripening in other fruits around them. Never store apples in closed plastic bags, or they'll ripen and spoil very quickly. Go with paper. If you want to store a sliced apple or a halved apple, do so in the refrigerator. These will dry out and brown very quickly, but a little spritz of lemon juice on the flesh of the apple will help to keep it fresh for longer.
Summary:
Learn about the different varieties of apples. Look for ripe apples. Store your apples properly.
