Problem: Write an article based on this summary: Mix flour, salt, and vinegar in a mixing bowl. Rub the solution onto the surface of your copper pipes. Let the solution sit on the pipes for 10 minutes. Rinse the pipes with warm water. Dry the pipes with a clean cloth.

Answer: Combine ¼ cup (32 g) of all-purpose white flour and ¼ cup (75 g) of table salt in a small mixing bowl. Mix the salt and flour together with a spoon so they’re thoroughly combined. Slowly add in 1⁄4 cup (59 ml) of white vinegar at a time and stir it into the salt and flour. Keep adding in vinegar until the flour and salt forms a thick paste, which should take about 1⁄2–3⁄4 cup (120–180 ml).  You can substitute lemon juice for vinegar if you want. You may use baking soda as a replacement for flour if you want. Dip a clean cotton rag into the paste that you created and thoroughly rub it over the surface of the pipes. Follow the grain of the copper pipe to prevent forming any scratches. The paste will break away any built-up residue and grime. Continue working in a back and forth motion until the surface of the pipe shines.  The grain of the pipes is the direction that the pipe runs. Clean from one end to the other rather than around the pipe. If you don’t have a cleaning cloth, you can also use an old, clean sock instead. Once you’ve applied the cleaning paste, leave it on your pipes for about 10 minutes so it can break down tougher build-up. Test the areas on your pipes by wiping it with your rag to see if the buildup comes off. If it doesn’t remove the buildup, then wait for an additional 5 minutes. Run the pipes under warm water from the faucet until all of the paste has been removed from them. If you can’t remove the pipes, then wet a cloth with warm water and wipe the paste off of the surfaces. Make sure you remove all of the paste from the surface of your pipe. Make sure there isn’t any paste left on your pipes since the acidity of the vinegar could cause damage to your pipes. Use a clean cotton cloth to wipe the water and any residual paste off of the pipe. Make sure the pipe is completely dry or else it could start developing tarnish and buildup again quickly. Once your pipes are dry, they’ll look shiny and new.


Problem: Write an article based on this summary: Don't try to cram. Keep yourself occupied. Eat and sleep. Be ready to roll on test day.

Answer: If it hasn't been made clear already, you cannot successfully prepare for the ACT the night (or even week) before. If you have been preparing long and hard, resist the urge to do a final cram the night before.  You're more likely to fry your brain and hurt your results on test day.  Trust your preparation over the long term. Yes, the test is important for your future, but try not to obsess over it.  Stimulate your mind and body to keep both sharp for test day and to take a breather from test preparation.  Exercise is good for the body and mind, and thus a beneficial distraction.  It will help keep you energized as your approach test day. It is not a waste of brainpower to think about or work on non-ACT ideas or projects.  Indeed, they will help keep your mind stimulated and ready for action on test day. Good nutrition and sufficient sleep during preparation and leading up to test day will benefit you far more than sacrificing one or both in the name of a little more study time. Know where you need to be, when you need to be there,  and what you need to bring (ID, pencils, approved calculator, etc.) well beforehand. For more detailed information on preparation just before test day and strategies for test day itself, see How to Ace the ACT.


Problem: Write an article based on this summary: Decide on the posts' spacing. Mark the spaces with stakes. Use a post hole digger to dig holes at each stake marker. Treat the bottom third of the posts with a protective seal to help prevent damage from underground moisture.

Answer: This should generally be around six to eight feet apart, depending on the type of fence and the terrain it will be installed upon. Take the time to carefully evaluate their position, as failing to align posts properly will impact the solidity of the overall structure. To ensure a stable fence, plan to set your posts at a depth of 1/3 of their length. This is the depth you'll need to dig your holes. Allow to stand overnight so the wood can become saturated.


Problem: Write an article based on this summary: Support your couch cushions. Cut a piece of plywood to fit underneath the sofa cushions. Repair the springs.

Answer:
You can buy “sofa savers” for sofas online or at home goods stores like Bed, Bath & Beyond. Put these supports underneath your couch cushions to give them more support and firmness. Measure the space underneath the sofa cushions and cut a piece of plywood to those dimensions. Place it underneath the cushions. You will feel more support underneath the cushions, and the couch should sag less. Flip the couch over and expose the springs underneath the couch. To repair the springs of your sofa, you will need to wear glasses and use a pair of pliers. If you see any springs that are bent out of place (i.e., they look different from the rest of the springs), bend them back with the pliers gently.
