Problem: Article: Try switching to a toothpaste designed to help with sensitive teeth. Toothpaste containing arginine has been shown to be more effective than sensitive toothpastes that use potassium as the active ingredient. Make sure to use a toothbrush with soft bristles. Harder bristles  can damage tooth enamel and cause gums to recede, leading to sensitive teeth.  Also be careful not to press too hard when you brush - this can also damage gums and enamel. Gels designed to numb tooth pain are sold over the counter and can also be applied in the dentist's office or as a prescription. However, many dentists and the Food and Drug Administration warn against using numbing agents like benzocaine, especially to treat sensitive teeth in small children. If your sensitivity is caused by grinding, you can wear a protecting guard during the night. Your dentist can make a custom-fitted mouth guard for you. They are available over-the-counter as well, but because they are not fitted to your mouth specifically, an OTC guard may cause more harm than good.  If you do notice yourself grinding your teeth during the day, position the tip of your tongue between your teeth. At night, hold a warm washcloth against your cheek, near your earlobe. These both relax your jaw.  Try massaging your jaw and sticking to soft foods until the pain subsides. Acetaminophen and ibuprofen can help reduce the pain of sensitive teeth. Don't use this as a long-term solution, however, as pain medications have side effects. While numbing agents and special toothpastes may temporarily ease the pain of sensitive teeth, you won't be able to truly resolve tooth pain unless you know the underlying cause — whether it's due to dry mouth, grinding your teeth, acid reflux, acidic food and drink, etc. Consult your dentist about your tooth pain so she can help you properly diagnose the issue and choose the best treatment.   Tooth sensitivity may be cased by brushing too hard, dental decay, tooth fracture, dry mouth, diet, brushing too hard, acid reflux, gum infection, and more. Your dentist can offer treatments such as a fluoride varnish, a fluoride tray, prescription toothpaste, and/or a mouth guard.
Summary: Change your toothpaste. Change your toothbrush. Use a numbing agent if you must. Use a night guard. Take an OTC pain medication. Talk to your dentist about the cause of your tooth sensitivity.

INPUT ARTICLE: Article: Oftentimes, you go out without the intention of spending money but end up getting hungry. Social events often revolve around food. You may, for example, go to a free concert thinking you won't spend a time, only to be tantalized by the smell of the hot dog stand. You may go hang out at a friend's place and end up pitching in for pizza even though you planned on not spending money. Eating before a social event can help you resist this temptation.  Have a big meal before you go out. Stick to healthy foods that won't leave you hungry later, like whole wheats, fruits and vegetables, and lean proteins. This can also be helpful if you're trying to lose weight. You will fill up on healthy foods and won't waste calories on junk food. If you do end up spending a little money socializing, try not to do so at a bar. Bars are notorious for having high prices. The cost of alcohol at a bar is much greater than it would be simply buying alcohol at a store. If your friends want to get drinks, suggest you have drinks at someone's place rather than out at a bar. Even free events can have unexpected costs, so watch out for these. Try to eliminate hidden costs when you can. You may, for example, have to pay for parking at a free concert. You can eliminate this cost, however, by taking public transportation. It's not easy having to budget while wanting to be social. Your friends may sometimes struggle to understand the issue. Try to encourage them to lighten up and spend.  If your friends are trying to pressure you into spending money, say something like, "I know you guys want me to have fun, but I'm really trying to save right now." It can sometimes help to explain your financial situation. For example, "I'm trying to pay off my credit card right now" or "I really need to save up for that new car."

SUMMARY: Eat before you go out. Avoid bars. Pay attention to hidden costs. Encourage friends to be understanding of your money issues.

In one sentence, describe what the following article is about: Place your camera on a flat surface when you do this to get the straightest picture possible. Do your best to aim the camera at the “center” of the object. This will be the thing that you aim the camera at for your second picture. After you take the picture, measure the distance from the object to the camera. You may end up not needing this information, but it could be very helpful later. After you move the camera, turn it slightly so that it’s focused on the “center” of the object again. Make sure you don’t change the distance between the object and the camera; you just want to change the angle that the next picture will be taken from.  If you want to be extra safe, measure the distance from the camera to the object after you move the camera. This way, you can make sure you only changed the angle and not the distance. You should only move the camera about 3 inches (7.6 cm) because this is the approximate distance between the centers of your eyes. Make sure that the object hasn’t moved or changed since you took the first picture. The second picture should look nearly identical to the first picture, but with some tiny changes. For instance, the smaller details in the image may seem to be “looking” into the distance relative to where they were “looking” in your first picture. This is the biggest that your pictures can be if you want to look at them with a simple stereoscope. For bigger pictures, you’d have to use a mirror stereoscope, which isn’t as simple to make!  You can also make your pictures smaller, if you want. They may just be a bit harder to see with your stereoscope. If you’re using a digital camera, you can usually select this sizing option on the computer program that your camera uses. If you’re using a film camera, ask the clerk at the camera store to print your photos to this size.
Summary: Take a picture of an object at a distance. Slide your camera about 3 inches (7.6 cm) to the side. Snap another picture of the object from this new position. Print the 2 pictures to be 6 by 9 centimetres (2.4 by 3.5 in) big.

In one sentence, describe what the following article is about: Forget about the classic 'listen to your teacher, do your work, work consistently' strategy. Instead, think long term. Relax, enjoy and have fun throughout the year. There is really no need to work your butt off for the internal examinations or try to impress your teachers because, in the IGCSEs, "only the boards matter!". When you do homework, you can test what you know on each subject, and you can look back at it for revision.  Every weekend, just read through the text. One chapter of each subject; whichever one you prefer, but, try not to repeat the same ones every time. A steady, ongoing state of learning will have you more than ready by exam time, rather than trying to cram at the last minute. Those breaks during the year provide a more relaxing, yet still work-focused, time to keep preparing consistently. If you use these times to keep learning, you won't stress anywhere near as much as those leaving it all until the last minute. This deeper learning and revision must begin well before the boards, so plan out a timetable and give up on about 90% of the fun you have been having at this point. It's serious study time! It may seem a long-term but it short in the bigger scheme of things and yet has such long-term impact, so dedicate yourself to the long-term outcome for the best.
Summary:
Throw out previous thinking. Do your homework consistently during the year. Keep it in your mind that you need to get grades from A-star to C, because a D or lower is a fail. Read voraciously. Use your holidays and vacation as a time to study. Prepare in earnest from about six months, then really knuckle down at three months to go.
