Problem: Write an article based on this summary: Put the tubing in boiling water for a thorough sterilization. Use the dishwasher for a quick and easy option. Sterilize the tubing in the microwave if you're in a pinch.

Answer: Let the tubing sit in a pot of boiling water for 5 minutes. Do not add soap or cleaners to the water, as this can get into the tubing. Put the tubing on the top rack of the dishwasher and run the dishwasher on the hot water cycle as well as the heat drying cycle. The heat in the dishwasher will kill any bacteria or germs. Make sure the tubing is dishwasher safe. Some breast pump tubing comes with a microwavable bag you can use to sterilize it. Fill the bag with a few inches of water and place the tubing in the bag. Then, seal the bag shut. Put the bag in the microwave and run it on high for 3 minutes. Follow the manufacturer's instructions on the back of the bag to ensure you use it correctly. Keep in mind microwaveable bags do not meet FDA standards for sterilization, but they can be used if you are in a hurry.

Problem: Write an article based on this summary: Check your pulse at your radial artery. Take your pulse underneath your jaw. See a doctor if you detect any abnormalities in your resting heart rate.

Answer: This is one of the easiest places to measure your heartbeat because you have a large artery right below the skin. Each time your heartbeats, you will feel a pulse as the blood rushes through your artery. Hold out one arm, palm up. Gently press your index finger and middle fingers to the inside of your wrist between the bone and tendon near your radial artery. This will be approximately one inch below your wrist on the same side as your thumb. You should feel soft tissue beneath your fingers, not bone. You may need to move your fingers around or press slightly harder until you feel it. Count the number of beats for 15 seconds and multiply by 4 to get the number of beats per minute. Use a clock to measure the 15 seconds rather than trying to simultaneously count your pulse and the seconds. This is another location where you should be able to easily and quickly find a strong pulse. Put your index and middle finger to the left of your windpipe where your neck connects to the tissues underneath your jaw. You should be able to feel your pulse on either side of your windpipe, but it might be easier to find on the left side. You may need to move your fingers around and press a little harder until you feel it. Use a clock or stopwatch to keep track of 15 seconds, count the pulses you feel, and then multiply by four. You should get about the same result when you measure your pulse at your wrist or your neck. Your resting heart rate is the number of beats per minute when you are inactive for at least five minutes; however, if you were exercising, it may take longer for your heart rate to slow down. A person's resting heart rate naturally varies based on how active you are, how fit you are, how warm or cold it is, whether you are standing, sitting, or lying down, your emotional state, your body size and what medications you are on. Consult a doctor if: Your resting heart rate is usually over 100 beats per minute. This is called tachycardia. Your resting heart rate is below 60 beats per minute, if you are not an athlete. This is bradycardia. Other symptoms that may accompany this condition include fainting, dizziness, or being out of breath. If you are an athlete, a low heartbeat may mean you are in good shape. However, it should not be below 40. Your heartbeat is irregular.

Problem: Write an article based on this summary: Take a placement test if you already know some Spanish. Use an app if you need more versatility. Take a university course online if you want more structure.

Answer: A placement test can tell you what level you should start at. While there are plenty of courses available for absolute beginners, if you already know some Spanish you might get bored at that level. A placement test is also helpful if it's been a while since you were exposed to any Spanish. For example, if you took Spanish in high school but you graduated 5 years ago and haven't used Spanish since, you may need a refresher. There are several websites where you can take a free placement test that use the Common European Framework of Reference for Languages (CEFR). Most language learning courses use this guideline as well. For example, Lengalia has a test at https://www.lengalia.com/en/placement-test.html that covers grammar, reading comprehension, and oral comprehension. Tiatula in Spain also has free placement tests available at https://www.tiatula.com/spanish-placement-tests/. Some courses require you to sit down at your computer on a regular basis. However, there are also apps you can download on your smartphone or tablet. With one of these apps, you can practice language at any place and any time, allowing you to fit your learning into your schedule. Popular apps include Babbel, Duolingo, and Rosetta Stone Online. Some are free, while others require you to pay a monthly subscription for access. Subscription fees are typically around US$20 per month. Apps and other self-directed courses require motivation and discipline if you want to get the most out of them. With online university courses, you have an instructor who will hold you accountable for doing the work and maintaining a consistent schedule. You can find university language courses online at websites such as Coursera or edX. Open Culture also has a list of free online courses in Spanish available at http://www.openculture.com/freelanguagelessons. While some university courses are available for free, many of them are not. However, investing money in a course may also help hold you accountable for getting the work done.

Problem: Write an article based on this summary: Lay a cornerstone in each corner. Construct the corners by interlocking stones. Lay the stones down for the first layer of your wall. Stagger the rocks as you start new layers. Stack your wall at least 1.5 feet (0.46m) above the ground level.

Answer:
Load-bearing dry stack walls should be started at the corners. Begin constructing corners by laying 1 stone in the corner of the trench. Then lay 3 stones extending out in each direction. This forms the corner joint. If the wall is more than 1 stone thick, lay more stones parallel to the first ones. Act as if each section represents one stone. Construction bricks are designed to interlock at corners. The 4 stones you laid from each direction forms the first layer of cornerstones. For the second layer, overlap the first stone by laying another on top of it. Continue interlocking the stones as you build upward, alternating which side lays over the other. The interlocking stone structure should look like a zipper going up. Stack 3 to 5 layers of stones at the corner before filling in the rest of the wall. Then if you need to go higher, stack more layers at the corners. After constructing the corners, extend outward from here and fill in the rest of the trench. Interlocking bricks have shapes cut into them that line up with the other bricks. Fit the bricks together as you lay them in place. Place the bricks in the trench all along the perimeter to form the first layer. Make sure each rock you place is secure. Push it down to lock it in place snugly. Pound them down gently with a rubber mallet if you have to. Always stack a complete layer around the whole perimeter before starting another layer. When starting a new layer, each rock should overlap the joint between the rocks below it. This helps make your wall more stable. Continue this pattern as you stack more layers. If your bricks are smaller and you need to use more than one to cover the width of the trench, make sure the stones nearby touch each other. Otherwise, the wall won't be able to support much weight. Part of the reason you need a stem wall is to keep ground moisture away from the structure you're building. Stacking the wall at least 1.5 feet (0.46m) above ground level helps keep your structure dry and avoids water damage. Do not build the stem wall higher than 8 feet (2.4m). A wall higher than this requires extra reinforcement. Many localities even ban stem walls higher than 4 feet (1.2m) for safety reasons.
