Q: The first note in a scale is the C note. The order of the scale is C, D, E, F, G, A, and B, with the same pattern repeating after B. You can find the C key on a keyboard by looking for any pair of black keys that are surrounded on both sides by two white keys instead of one. C is always the key immediately to the left of the black key on the left side of that pair.  Note the pattern of white keys: three white keys enclosing two black keys, and four white keys enclosing three black keys. C is the white key on the left of the two enclosed black keys. This pattern is consistent on all keyboards. Every note on the keyboard is represented in this single 12-note octave, which is the term for an interval of notes that appear in the same order. Different octaves are higher or lower in pitch depending on where they are positioned in reference to the middle octave. Each black key has two possible notes based on the context of the music that you’re playing. For example, C sharp (C♯) and D flat (D♭) are the same key on the piano, but the note changes whether you’re moving up or down on the keyboard, or whether or not you’re pressing a pedal. This is because the sound created by the black keys is imperfect, and doesn’t correspond perfectly with the natural scale. The black keys usually play a supporting role in most compositions, so it will help to remember their order by starting directly above the white C note in the middle, which is C♯ or D♭.  The symbol ♯ is read as “sharp,” and the symbol ♭ is read as “flat.” The white keys are called “natural” tones, and are the main keys used in most songs. The black keys are known as “accidentals,” and contain sharp and flat sounds in tones in between the natural keys. Going from left to right, every group of notes between a C and B is called an octave. A standard 88-key piano has 12.5 octaves. A note determines the tone of a key, while the octave determines the pitch. The notes on the left are lower in pitch, while the notes on your right will be higher. You almost always start playing a song from middle C, which is a term for the octave in the dead center of your piano. A grand or upright piano has 88 keys, but there are electronic and modified keyboards with 44 or 49 keys. The more keys that a keyboard has, the more octaves the keyboard is capable of playing.
A: Learn the order of the white keys by finding C. Get familiar with the black keys by finding C♯/D♭. Familiarize yourself with the octaves on your keyboard.

Article: If using cupcake cases, arrange on a baking sheet now. If using a silicone cupcake sheet, simply have it ready. Mix to combine. Whisk together well. Stir to combine thoroughly.  Bake for 20 to 25 minutes. If they smell strongly earlier, test with a wooden skewer; if it returns clean after sticking into a cupcake, they're ready. Transfer the cupcakes to a wire cooling rack as quickly as possible when cool enough to handle. Let cool completely on the rack. Add standard frosting or make vegan butter cream.
Question: What is a summary of what this article is about?
Preheat the oven to 160ºC/315ºF. Add the flour, cocoa powder, baking soda and pinch of salt to the mixing bowl. Pour the soy milk, vinegar, sugar, oil and vanilla into another bowl. Pour the liquid mixture into the flour mixture. Pour into the cupcake cases or cupcake holes. Place into the oven. Remove from the oven. Frost as desired.

Problem: Article: The image must be clear in order to make it easy to cut out.  If you are drawing your own image, clearly outline the areas of the image that will be cut out for the stencil. Remember that you need to define the edges and the details of your image, or the stencil will not portray your original drawing. If you are using a photograph or an online image, you need to use a software program that can adjust the contrast and brightness of your image so that you have defined dark and light areas. It will probably be easiest to switch the image into purely black and white.  Make sure that your current design will work as a stencil. If you are attempting to create a complex image with textures or shadows, make sure that you design does not force you to cut whole sections out of the stencil. Alter the image so that the stencil will remain as a single piece.  Photo images also work best if you erase the backgrounds first. This may be the most time-consuming portion of the process. After the image has been printed, it may be a good idea to outline any areas areas in which the contrast remains ill-defined. You must have a clear image to cut out for the stencil.
Summary: Create the final image with clean lines and good contrast. Print  out the final image on a regular piece of computer paper (if applicable).

Q: When you purchase a digital anemometer it will come with an instruction manual. Read through the instructions carefully before you begin using the device. The instructions will provide you with directions for how to set-up and read your anemometer. The anemometer will come with a battery and you will need to install the battery in the back of the device. Unscrew the battery compartment in the back and place the battery inside. The device will likely have a power button on the front. Once the batteries have been installed, you can turn on the device and begin recording the wind speed. Most digital anemometers will have a variety of different measurement options. For example, you could calculate the wind speed in km/hour, mi/hour, ft/second, ft/minute, and knots. Press the unit button in order to scan through the different measurement options and select the one you would like to use.
A:
Read the instructions provided. Install the battery. Turn on the device. Choose your preferred measurement setting.
