Problem: Article: Coffee is a main source of antioxidants in many diets, and looking to stop coffee consumption means that you will need to find a new source of antioxidants for daily health. Decreasing your daily coffee intake may mean increasing the amount of tea you drink and/or the amount of fruits and vegetables you eat.Teas such as white and green tea have antioxidants that can replace those in coffee, but they also have caffeine. If you are trying to eliminate caffeine along with coffee, you may want to opt for whole fruits and veggies, or whole natural juices. Rather than decreasing the amount you drink incrementally, try drinking the same amount, but swapping some cups out for a coffee substitute such as tea or water. If you drink more than one cup of coffee per day, only substitute for one of them. If you normally drink one cup of coffee per day, drink a little less of it daily and then have some of your preferred coffee replacement.  Make sure you have your substitute handy at all times. Keep some tea bags at your desk, or in the car. If you don’t have your substitute handy, you’re likely to opt for a coffee when it’s convenient. Choose a substitute that you genuinely like. If you can’t stand the taste of green tea, you’re not likely to stick with it. Get used to drinking one cup less coffee per day. At the same time, you’re getting used to the substitute of your choice. This will help turn your new beverage choice into a habit. If you develop any caffeine withdrawal symptoms, such as headaches, take a caffeine-free pain reliever as needed. Once you’re ready, make the switch. By now, you should not be having withdrawal symptoms. You may find that you drink less of your substitute drink than you did of coffee. That is perfectly normal. You can always switch substitutes if you need to. You may eventually want to quit caffeine altogether, or do without all of the sugar in hot chocolate. Once you’ve quit coffee, quitting another beverage will likely not seem as hard.
Summary: Look for a replacement with antioxidants. Swap one of your coffees for a substitute. Repeat this for two to three days. Replace all of your coffees with the substitute.

INPUT ARTICLE: Article: This is a great rule of thumb to narrow down which dark lipsticks will work best on you. If you are cooler toned, you will want to balance that with a warmer colored lipstick. If you are warmer toned, choose a cooler toned lipstick.  If you aren't sure of your skin's undertones, learn how to figure it out here. If you're shopping at a cosmetics store, don't be afraid to ask for help selecting a shade. Typically, matte shades work best for daytime looks, and glossy shades are reserved for the evening. With a bold, dark color, the added gloss may be a bit too dramatic for the light of day – however, these rules can always be broken. Choose the finish you prefer. This isn't always possible, but take advantage if it is. If you're shopping at a cosmetics store, they will have a tester tube of lipstick. Use a cotton swab to apply the lipstick, and examine yourself in a mirror. The proper shade should brighten up your complexion. Take your time, and find the shade that flatters your face most. Brush your cotton swab on any area of tester lipstick that doesn't look touched to avoid germs.

SUMMARY: Select a lipstick that balances your skin's undertones. Choose between a glossy or matte finish. Test your lipstick shade before purchasing it.

In one sentence, describe what the following article is about: The pH is a measure of the concentration of hydrogen ions in a solution. A solution with a high concentration of hydrogen ions is acidic. A solution with a low amount of hydrogen ions is basic, or also known as alkaline. Hydrogen ions, also known as hydronium, are written shorthand as H+ or H3O+.  Know the pH scale. The pH scale is usually presented from 0 to 14. The lower the number, the more acidic the solution. The higher the number, the more basic the solution. For example, orange juice would have a pH of 2 because it is quite acidic. In contrast, bleach has a pH of 12 as it is quite basic. Numbers in the middle of the scale are neutral, such as water, with a pH of 7. One level of pH is a 10x difference. For example, when comparing pH 7 to pH 6, pH 6 is ten times more acidic than pH 7. Furthermore, pH 6 would be 100 times more acidic than pH 8. The pH scale is calculated by a negative logarithm. A negative logarithm of base b is simply how many times a number must be divided by b to reach 1. The pH equation can be seen as follows: pH = -log10[H3O+].  The equation can sometimes be seen as pH = -log10[H+]. Know that whether the equation has H3O+ or H+, they are the same. It is not vital to have a firm understanding of what a negative log is to calculate pH. Most calculators used at high school and post secondary level will have a log button. Concentration is the number of particles of a compound in a solution relative to the volume of the same solution. For pH, you have to use molar concentration for the formula to work out. Molar concentration, which is also called molarity, denotes the number of moles of dissolved compound per liter of solution. Its units are moles per liter (mol/L), also called molar (M). If you’re using a solution in a lab, the concentration will be written on the bottle. When working on your chemistry homework, the concentration will usually be given to you.
Summary:
Know what pH actually is. Define pH in an equation. Understand concentration.
