Problem: Write an article based on this summary: Know the deadlines and regulations. Master a verse of a song. Apply online. Find an open call. Pick out an outfit. Stay warmed up.

Answer: For X-factor UK, there are different dates and rules. Make sure you meet all the requirements and complete every step before all deadlines. You need to be 14 or older. This is regardless of whether you're in a group or a solo act. Or two songs, just in case the person before you sang the same one. You'll be singing it acapella (without any instruments or backing track -- just you) in front of an X-Factor team member and the crowd around you. Avoid being cliched. Only sing Whitney Houston, Michael Jackson, or Jennifer Hudson if you're just as good. Pick a song that you know won't be the 500th time your judge has heard it that day. If that's the case, you'll be compared to everyone else on two different levels. The judge doesn't have to know the song. In fact, it may be better if they don't. Before the season starts, there is an application form online at the website of your country's version of the X Factor. This is months and months in advance, so you may need to wait until the next season rolls around. There are plenty of auditions by "mobile van" each year. In fact, that's how James Arthur auditioned. Get connected on the website, Facebook, and Twitter for announcements. If you missed the online application, there's still an open call. Thousands of people do it. If one is in your area, great! Suit up and start practicing. In the UK, open call auditions were held in London, Birmingham, Manchester, Cardiff, and Glasgow. But there were tons of mobile van auditions -- just the beginning of the list is Aberdeen, Colchester, the Isle of Wight, and Dublin. On the audition notice received when you fill out your form, it explicitly says to stand out from the crowd. Personalities are so large there really is no limit. Whatever matches your personality, go for it. This show is all about spectacle. Here's what the form says: "Dress as the pop star you want to be - we are looking for the next big music sensation so make an impact. We also highly encourage everyone to bring along posters and banners to the open day - the brighter the better!" Fortunately or unfortunately (no one is quite sure), wearing your wedding dress or a plastic chicken on your head is not unheard of. You may stand out more by not trying too hard, believe it or not. If the audition is months away, don't quit. Run through your piece every other day or so until you can do it on one leg with your hands tied behind your back. Stay vocally healthy to boot. Load up on warm water. Stay away from alcohol (dries out your throat) and definitely don't smoke. If you're concerned you're getting a tickle, go for green tea, pineapple juice, and get on vocal rest. Don't strain your voice -- that'll just wear it out.

Problem: Write an article based on this summary: Press inward and outward with your arm to strengthen your rotator cuff. Use a resistance band to exercise your rotator cuff. Do rotational exercises with dumbbells. Start with a bar exercise for your scapular muscles. Do a one-arm press. Try a weighted shrug. Use a dumbbell while on your stomach. Try a rotational swing. Make cardiovascular exercise a regular part of your routine.

Answer: With your elbow at a 90-degree angle, your upper arm against your body, and your other hand directly in front of you, press inward against your other hand. Hold for 5 seconds. With your arm in the same 90-degree angle, press outward against a wall or other solid surface for 5 seconds. Do this 20 times apiece, then repeat with the other arm. This exercise, along with using a resistance band and doing rotations with dumbbells (both described in this section), help strengthen the rotator cuff. Strengthening the muscles around your shoulder can reduce the likelihood of dislocating your shoulder. Repeat all these exercises up to 5 times a day. Attach a resistance band to a solid object, like the knob of a closed door. Stand with your side facing the band, the elbow closest to the door at a 90-degree angle, and that upper arm against your body. Pull the band inward toward the center of your body for 5 seconds, but keep your upper arm secure against your ribs. Repeat this 20 times, then turn around and switch to the other arm. After that, attach a longer resistance band to the solid object -- or, if necessary, hold a shorter band securely in the hand you're not exercising with. Stand in the same position as before. This time, however, grab the band with your arm that's furthest from the doorknob. Pull outward while keeping your upper arm against your ribs, repeat 20 times, and switch arms. Lie down on your side on a bench. Place a dumbbell in the arm that you're lying on, which should be bent at the elbow at a right angle. Lift the dumbbell up to your chest, rotating your arm inward. Repeat 20 times. Switch to the other arm, starting with the dumbbell at your chest. Keep your upper arm against your side while you rotate your forearm and lift the dumbbell upwards. Repeat 20 times. Move to the other side and repeat the whole process. You can use filled water bottles or cans of food in place of dumbbells. You can use a very light bar at first, or even a cane or broomstick. Lie down on your back, and hold the bar just over your upper chest with your fists close together (or even touching). Lift the bar upward until your arms extend fully. Lift your shoulder blades up and lower them back down. Then, lower your arms back down. Repeat 20 times. By lifting your shoulder blades, you're working to develop your scapular muscles. These muscles help balance the ball in the socket of your shoulder joint. That means strengthening them is also essential for keeping your shoulder from dislocating. Lie on your back, and hold a dumbbell in one arm in front of that same shoulder. Press it upwards until your arm is fully extended. Repeat 20 times. Do this exercise with both arms. For an even more thorough workout, move up to an inclined position, and repeat this exercise. Then, do this exercise while sitting up or standing, again by pressing upward. Hold weights in your hands while standing. Your arms should be at your side, palms facing forward, with the weights against your upper legs. Lift both shoulders up in a shrug, and then release. Repeat 20 times. Lie on your belly, and hold a weight in one hand behind your back. Press the weight upward away from your body. Repeat 20 times and switch sides. Lean one arm on a table with just that side facing the table. Hold a weight in your other arm, resting it against your upper leg. Lift the weight out to the side, and slowly bring it back in. Repeat 20 times, and then move to the other side. Strength training will improve your shoulder muscles, but so will cardio workouts. They will also increase your flexibility. Aim for 30 minutes of exercise most days of the week. Pick exercises that work your upper body, such as swimming, tennis, or basketball.

Problem: Write an article based on this summary: Measure the sweetened condensed milk. Stir in the water and the acid. Allow the mixture to stand for 5 minutes.

Answer:
For the sour milk, you'll need cup (103 g) of sweetened condensed milk. Carefully pour it into a measuring cup to ensure that you get the right amount. cup (103 g) of sweetened condensed milk is about of a standard 14 ounce (397 g) can. Add the sweetened condensed milk to the measuring cup slowly. Because it's so thick and sticky, it can be difficult to get the milk out if you add too much. Once you have the proper amount of sweetened condensed milk, add cup (118 ml) of cold water and 1 tablespoon (15 ml) of white vinegar or lemon juice to the measuring cup. Mix the ingredients together well until they're fully blended. When the milk is mixed with the water and acid, let the mixture sit for about 5 minutes. You'll know that the sour milk is ready when you notice some curdled bits in it. You'll make 1 cup (237 ml) of sour milk from the recipe.
