Problem: Write an article based on this summary: Preheat the oven to 350 degrees. Mix the wet ingredients in a medium mixing bowl. Mix in the flour. Pour the batter into a greased rectangular pan. Bake the cake. Let the cake cool for 10 minutes. Invert the cake onto a tray.

Answer: Put the butter, sugar, vanilla, eggs, and milk in a bowl. Beat with a whisk or an electric mixer until the mixture is smooth and creamy. Slowly add the flour to the wet ingredient mixture, stirring it in well with a whisk or electric mixer. Keep beating the mixture until you no longer see specks of white flour. Use butter or cooking spray to oil a 13" x 9" pan and pour the batter into it. Put the pan in the oven and bake the cake until a toothpick inserted in the center comes out clean, about 20 minutes.  Allow it to finish cooling completely while you make the icing.


Problem: Write an article based on this summary: Understand the differences between peripheral and centralized bone scans. Know the purpose of a bone density test.

Answer: Besides cost and ease of screening, these tests also vary in accuracy. Some physicians will start with the peripheral test and only conduct the centralized test if the first screen indicates poor bone density.  Peripheral machines are small and portable, and they check bone density on the periphery of your skeleton, such as finger bones or the heel. They are much cheaper but not always a good indicator of bone health in bones that are the most likely to break. Centralized bone scans involve a large X-ray machine with a movable arm that will scan different parts of your skeleton while you lie on a padded table. This machine tests bone density at your hip, lower back, and forearms to get a good measure of the strength of bones that are most likely to break in a slip or fall. Most individuals receive bone density scans to check for signs of osteoporosis.  Bone density scans are often used to detect your individual risk of bone fracture and your personal chance of developing osteoporosis if you do not currently have the condition. Bone density scans can also be used to monitor the effectiveness of osteoporosis treatments.


Problem: Write an article based on this summary: Swipe right on your iPad's screen to unlock it. Open your "Settings" app. Scroll until you find the "Passcode" option, then tap it. Tap "Turn Passcode On". Enter a passcode of your choosing. Confirm your passcode by typing it in again. Press your lock button to lock your iPad. Swipe right on your iPad's screen, then enter your passcode.

Answer: Once you enable your passcode, this is the screen on which you'll enter it. This is the grey gear app on your home screen. If this is your first time enabling a passcode, "Turn Passcode On" will be the only selectable option. If your iPad supports Touch ID, this option will be called "Touch ID & Passcode". Your iPad will prompt you for your desired 6-digit passcode. You'll need to enter it again exactly the same way on the next screen to verify. If both your new passcodes match each other, you'll be taken back to the "Passcode Lock" screen. You still need to confirm that your passcode is active. Your iPad is now passcode-protected! You can change or remove your passcode at any time in the "Passcode" menu.


Problem: Write an article based on this summary: Choose the right size for your project. Apply the adhesive size. Allow time for tack to develop. Test the tack.

Answer:
“Size” is the adhesive material applied to the surface that makes the copper leaf stick to it. There are two options available – water-based or oil-based size. Oil-based size is the most traditional choice. Quick-dry oil size reaches tack (the required “stickiness” to adhere the copper leaf) in about two hours. It is meant to be used for small projects or whenever you have a limited time frame to work within. Slow-set oil size will reach tack in ten to twelve hours. It is intended for larger projects that require a lot of work time.  Water-based size is an alternative to the more typical oil-based size. It comes to tack within twenty minutes, and remains workable for about thirty hours.  Water-based size is not burnishable. If you plan to burnish the surface, use oil-based size. Adhesive size goes on wet. Use a paint brush to apply the size carefully to the surface. Even application is desirable for best results. Use the paint brush to work the size to an even coat as you spread it over the surface. Make sure you cover all areas that you want to gild. Copper leaf will not stick to a surface that does not have size on it. Once applied, you must give the size the proper amount of time to reach tack before applying the copper leaf. Tack times vary based on which kind of size you use. Following the correct tack time procedure will greatly affect the final look of your project. For the most professional looking results, read and follow the tack time instructions precisely. Gently run the back of your knuckle over a small area of the surface. Listen for a squeak sound, which indicates tackiness has been reached. If the size is still too wet to apply the copper leaf, it will come off on your skin. When it’s ready, it will feel sticky but will not come off on your skin. Monitor the size carefully and test the tack every half hour until it has been reached.  Once the size becomes too dry, you will have missed your opportunity to apply the copper leaf. It must be applied to a surface with proper tack. If you live in a very warm or dry environment, keep in mind that tack time may be reduced.
