In one sentence, describe what the following article is about: The simplest way to locate previous cost data is with your own memory. Perhaps there is some item at the grocery store or shopping mall that you've been buying for years at the same price. This could be a staple of your weekly grocery shopping trips or a clothing item you buy regularly. For example, imagine that the price of a gallon of milk has been $2.50 for a number of years. This represents the previous price for the purpose of your cost increase calculation. If the price of an item you've purchased in the past has increased, you can now calculate a cost increase percentage for the item. However, you will need the item's current cost first. Check the store for the current price of the item in question. For example, imagine that a gallon of milk, that has always gone for $2.50, is now priced at $3.50. You can now calculate the cost increase percentage to know just how much you are being charged at the new price in relation to the old price. Before comparing, make sure both values (your previous and current values) refer to the same product. If one is better in some way, your costs are not directly comparable. In some cases, locating previous cost information is not as simple as remembering the former cost of an item. For example, when comparing costs from long ago to now or finding cost increases on an item you've never purchased you'll need to locate cost information elsewhere. The same is true for cost measures (rather than items), such as the consumer price index (CPI), a measure of average consumer prices in the U.S., or the purchasing power of the U.S. Dollar.  In these cases, you will need to do some online research to locate previous cost figures. Try typing in the item and year you are interested in, along with "cost" or "value," to locate cost information for that time. For example, cost information for various consumer goods from 1900 until the present can be found at http://mclib.info/reference/local-history-genealogy/historic-prices/. For all historical cost information you locate, you will also need a modern figure to compare it with. Try to locate the closest modern version of whatever item or measure you are comparing. Make sure to avoid comparing items that are different due to different levels of quality or additional features, for example. Use the most current information from the current year in your calculations.
Summary: Recall the previous price of an item. Check the item's current price. Research historical cost information. Locate modern cost figures.

The smell of your fermenting wine can attract insects so be sure to close your container enough to keep insects out while still allowing air to flow in and escape. You can use a crock lid designed for this purpose or stretch a cloth or t-shirt over the opening and secure it in place with a large rubber band. Place the covered crock in a warm area with a temperature around 70 degrees overnight. Putting the crock in a cool place won't facilitate the growth of the yeast. Storing it in a place that's too warm will kill the yeast. The best bet is to store your fermenting wine in a place that is room temperature. Now that your wine is fermenting, your winemaking process will move a lot slower. The day after you make the mixture, uncover it and stir it thoroughly before covering it again. Repeat this process every 4 hours or so the first day, then keep stirring a few times per day for the next 3 days.  The mixture should start bubbling as the yeast moves into action. This is the fermentation process that will lead to delicious wine. When the bubbling slows down, about 3 days after it begins, it's time to strain out the solids and siphon the liquid into your carboy for longer-term storage.  Once you've siphoned it into the carboy, affix the airlock to the opening to allow for the release of gas while preventing oxygen from coming in and spoiling your wine. If you don't have an airlock, you can use a small balloon placed over the opening. Every few days, pull off the balloon to let out the collected gas and replace it right away. Let the wine age for at least one month. It's better if you can let it age for up to nine, during which time the wine will mellow, enriching the taste. If you used extra honey in your wine, it's better to age it on the longer side, or it may taste overly sweet. To prevent the wine from catching a bacteria that could cause it to turn to vinegar, add a Campden tablet to the mixture as soon as you remove the airlock. Siphon the wine into your clean bottles, filling them almost to the top, and cork them immediately. Allow the wine to further age in the bottles or enjoy it now! Use dark bottles to preserve the color of red wines.

One-sentence summary -- Cover your crock and let it sit overnight. Stir your mixture a few times per day. Strain and siphon the liquid. Age your wine. Bottle the wine.

Problem: Article: Avoidance is sometimes the easiest way to ignore someone. If someone is getting on your nerves, try to keep your distance as much as you can.  You can avoid places they're likely to hang out. If an annoying co-worker always eats lunch at noon, try eating lunch outside of the office or taking a later lunch. Avoid social situations where you're likely to see that person. If annoying person from school is going to be at party this weekend, try making other plans. When you're in the same room with someone who annoys you, be aware of your eyes. If you accidentally glance at the person, this could result in eye contact. This can be misinterpreted as an invitation to come over and talk. When you're around the person, try not to look at them. This will help minimize interactions. If you work with someone, you sometimes have to communicate with them. It may be easiest to do it through others. You don't have to be rude about this. Do not, for example, say within the person's earshot something like, "Could you tell Jeff, who I'm not speaking to, to put his dirty dish in the sink?" You can, however, ask others to deliver information when necessary. For example, you're working in a group for a work project. The annoying person is in your group. You may ask one of your group members to talk to the person, or you might only reach out to them via email or text message. You can't completely avoid talking to someone, especially if you see them at work or school. You don't want to give a complete silent treatment when someone's talking to you, so work on curtailing your responses. When someone talks, give curt responses like "Hmmm" and "Okay." This will hopefully send the message that you want some space. If someone is pessimistic or highly critical of things, try to ignore it. Ignoring it may help you stay positive without their negativity affecting you.  For example, if your office mate constantly complains about how much work they have, try ignoring them so that you don't feel bad about your own work. You shouldn't ignore everything. If a co-worker always teases you to the point you feel uncomfortable around them, confront them. You can say, "Would you mind not joking about my outfit? I enjoy what I wear, but it makes me feel bad when others criticize how I dress." If the annoying person is very aggressive towards you, adopt the buddy system. Try to have friends or co-workers accompany you places you're likely to see the person. Friends can, for example, walk with you between classes or eat lunch with you to keep the annoying person away.
Summary:
Stay away from the person. Avoid eye contact. Communicate through others. Curtail your responses. Tune out negative behavior. Find strengths in numbers, if necessary.
