Problem: Article: Emeralds come in a range of colors. Color is one of the most important factors in determining the value of an emerald. The variance of color in emeralds is due to differing amounts of chromium, vanadium, and iron in the environment in which the stones formed. Color can be subdivided into the categories of hue, tone, and saturation. Hue is probably what you think of when you hear the word "color." An emerald's hue is its specific type of green. Emerald hues can range from bluish-green to a more yellow-green. For example, Zambian emeralds are characterized by deep bluish greens, while Brazilian and Colombian emeralds often take on a rich, pure green hue. Tone refers to how light or dark the color of an emerald is. Emeralds can range from very light green to very dark green in tone. The association of tone and value is somewhat complicated. Darker emeralds are often considered more valuable, but if an emerald becomes too dark, it becomes less valuable. Emeralds with medium to medium-dark tones are the most valuable emeralds in the market. Emeralds with pure green or blue-green tones are the most desirable, in part because blue-green emeralds are associated with a very famous and highly-regarded gem mine in Columbia called the Muzo Mine. Be aware that emeralds that are too yellow or too blue may not be considered real emeralds and are therefore far less valuable. Saturation is tied to the gem's transparency. Emeralds with high saturation (which means that they are highly transparent) are more valuable than emeralds with low saturation. Saturation can be tied to both inclusion and tone; very included gems can appear less transparent. Similarly, very dark green emeralds do not absorb much light, so they appear duller than lighter emeralds.
Summary: Understand the importance of color. Identify an emerald's hue. Look at an emerald's tone. Evaluate an emerald's saturation.

INPUT ARTICLE: Article: The 20 minutes can be at any point during the day, but try not to split the 20 minutes up into smaller increments. Dedicating 20 minutes each day to reading (and sticking to it) will help turn reading into a habit. Set a timer for 20 minutesor 30 or 40 minutes, if desiredso that you know how long you've been reading. If you find yourself wanting to keep reading after the 20 minutes are up, keep going! Many times, you'll start reading before going to bed and will only get through a couple of pages before becoming too tired. By reading right after you wake up, you'll be much more alert and will be more interested in the book. Try reading both before bed and in the morning to take advantage of down time. There are lots of times you could be reading in your spare time, like when you're at the doctor's office, at a park, or waiting for a lunch date to show up. By keeping a book in your purse, car, briefcase, or backpack, you'll be able to read during any free moments you have. Reading during things like television commercial breaks will help you make use of even more reading time. If you take a bus, train, or other type of public transportation to work, bring a book with you to read during the commute. If someone else drives you to school, work, or other activities, use this time to get in some extra pages. While you can't read a book if you're driving, you can listen to the book on tape. Listening to an audiobook requires the same mental process as reading a book, so it's fine to do this. There are book apps that you can download on your phone, tablet, or computer, making it easy to read even if you don't have a physical book with you. Peruse the books available on these apps to find one that you're interested in. There are many books you can download on apps that are completely free, while others will cost money. If you download the app on all of your devices and read it on different ones, most apps will sync together, making it easy to pick up your reading spot no matter which device you're using.

SUMMARY: Set aside at least 20 minutes of dedicated reading time each day. Read after you wake up as opposed to right before bed. Keep a book with you at all times. Take advantage of travel time. Use technology to fit in extra reading time.

In one sentence, describe what the following article is about: Copy cells A1 through B5 and paste in cells C1 through D5. This will copy the formulas you previously entered. You can calculate the future value of an account with a varying interest rate and additional monthly payments using an amortization table. These can be found online by searching for "compound interest amortization tables."
Summary: Predict results by changing the variables. Use an amortization table.

In one sentence, describe what the following article is about: If you cannot consume dairy for any reason, this is a great frosting to use. You'll need: 125g soy or olive spread 500g icing sugar/confectioners sugar 80g cocoa powder 100ml soy, almond or rice milk 2 teaspoons vanilla extract or essence. Beat with an electric mixer until it turns creamy. Because the consistency of soy/olive spread is thinner than that of butter or stick margarine, you don't want to over-beat the spread. Doing so could thin it out too severely, causing your frosting to become too runny. Add half of the icing or confectioners sugar to the creamed spread. Add 2 tablespoons of the non-dairy milk. Beat again, until the mixture turns light and the volume grows. Add the rest of the icing or confectioners sugar, the cocoa powder, the remaining non-dairy milk and the vanilla. Beat more, until well combined. The resulting mixture should have a velvety, creamy texture. Add a bit more non-dairy milk, 2 tsp (10 ml) at a time, if it's a little stiff. Similarly, add more sugar, 2 tsp (10 ml) at a time, if the frosting seems too thin. This frosting is suitable for those pursuing a dairy-free diet.
Summary:
Gather the ingredients. Add the spread to a mixing bowl. Add the sugar and non-dairy milk. Mix in the remaining ingredients. Spread on the cake or cupcakes.
