INPUT ARTICLE: Article: It may sound gross, but having day-old hair actually helps the tiara stay on better. If you must wash your hair, avoid using conditioner. This will give your hair some texture and "grip," and help the tiara stay on longer. This include applying hairspray. If you apply hairspray after you put on your tiara, you will dull the surface and make it sticky. Try to angle it slightly, so that the prongs go into your hair. It will blend in better with your hairstyle. Try not to just plop it on top of your head. To ensure that the tiara will not fall off, use bobby pins to hold it in place. Place the bobby pins in such a manner that they will be hidden, and will not interfere with the design of the tiara. This will cause the tiara to drag back painfully. Instead, put the tiara on first, then clip the veil directly to your hair.

SUMMARY: Don't wash your hair. Style your hair first. Slide the tiara carefully in the middle of the head. Use bobby pins to secure the tiara. Don't clip veils to tiaras.

In one sentence, describe what the following article is about: When you are near water, it is smart to get in the habit of surveying your surroundings. The first step in helping a drowning victim is being able to spot someone in trouble. Lifeguards call surveillance of the area "scanning and observing".  To scan and observe, you should spend a few seconds every couple of minutes looking around your area. Look at the water, and also look at the pool deck or beach. Keep your eyes out for people in distress, or in potentially risky situations. For example, if there is someone swimming far from shore in choppy waters, you'll want to keep a close watch on them. Keep your eye out for the elderly and young swimmers. Get in the habit of scanning and observing your area whenever you are near water. This is especially important if there are children with you, or others who are not strong swimmers. Active drowning means that the person is in the process of drowning. They will be impaired due to inhalation of water. There are several things to look for to determine whether someone is actively drowning.  Active drowning can begin within 20 seconds of the person being in distress. An active drowning victim will not be able to call for help. While an active drowning victim might still be vertical in the water, they will be unable to move towards help or safety. Active drowning victims will not be able to wave for assistance or reach for equipment. Once drowning has begun, the victim cannot voluntarily control his arm movements. Active drowning victims typically struggle on the surface for 20-60 seconds before being submerged. Active drowning victims will have their heads tilted back so their mouth and nose is above water, this is an instinct. There are many other types of problems that can occur in swimmers. Make sure you are aware of different signs so that you can accurately assess the situation. For example, a distressed swimmer is a person who may have become tired or suffered a cramp. They may call out for help and may appear to be flailing.  A passive drowning victim is someone who is unconscious in the water. Assume the person needs medical attention and call for help. A tired swimmer might be using short, weak strokes and appear to be looking for something to cling to. They might call for assistance. Once you have determined that you are looking at an active drowning victim, get ready to reach the person. Based on your scanning and observing, you should be able to tell whether you need to go in the water or whether you can offer assistance from land. Take any tools you need, such as a flotation device, life vest, or pole.  Alert someone else on the shore if you are swimming out to rescue the victim. You want someone else to be aware of the situation. Have them call for help. Do not attempt a rescue unless you are a strong swimmer and know what you are doing. If you are a weak swimmer, you can put both yourself and the drowning victim in danger. The assistance of a flotation device even if you are a strong swimmer is important.  Most professional lifeguards carry some sort of flotation device.
Summary: Practice scanning and observing. Learn the physical signs of drowning. Recognize other issues. Prepare to reach the victim.

INPUT ARTICLE: Article: For a square of side length S, the perimeter is simply four times the side length: P=4s. Depending on the assignment, you may need to measure the side with a ruler, or look at other information on the page to determine the side length.  Here are some examples of perimeter calculations:  If your square has a side length of 4, then P = 4 * 4, or 16. If your square has a side length of 6, its P = 4 * 6, or 24.

SUMMARY:
Recall the formula for the perimeter of a square. Determine the length of one side, and multiply it by 4 to find the perimeter.
