Article: Look for a dark pool of water. Watch how the ripples flow over the water. These ripples are formed by the wind pushing the water and breaking its surface. The ripples will flow in the direction of the wind. If you're not near a large body of water, put out a pan or bucket of water. You should still able to see the wind rippling on the surface. As you are looking out over the water, find a horizontal (left to right) stretch of water that is roughly 15 yards (14 m) wide. Observing the direction of this strip is a more accurate representation of wind direction than watching individual ripples. The strip will travel the same direction that the wind is blowing. When detecting subtle variations in wind direction, such as on a sailboat, you should be looking forward and back. Watch how the wind is affecting the water in front of you by focusing on a horizontal stretch of ripples in front of you. Also, glance back behind you to see how the wind is behaving there. This allows you to observe changes in the wind directly rather than waiting for your boat to react. Whether you are looking forward or back, you will use the same technique of identifying a horizontal stretch and observing the ripples.
Question: What is a summary of what this article is about?
Watch the ripples. Look out to a horizontal plane. Determine wind patterns by watching the water from a boat.

Problem: Article: Keep your tree in as cool a spot as possible away from any heaters, radiators or direct sunlight. In order to protect your living tree, use LED lights that don’t give off heat and hang lighter ornaments that won’t weigh down or damage your tree. Continually water your living tree while it is indoors so it doesn’t dry out. If the tree dries out, it may be unable to recover.  Check the water level in your tree’s basin regularly.  If the root ball of your tree is wrapped in burlap, place the root ball in a tub. Add mulch on top of the root ball to help increase moisture.  Ensure there is 1-2” of water at the bottom of your tub or container. Any more than that may drown the roots.  To add more moisture, use a spray bottle to spray water onto the leaves and branches of the tree. Be careful when spraying near lights or ornaments. As an alternative to adding water, you can place crushed ice overtop your tree’s root ball.
Summary: Place your living tree in a cool spot. Decorate carefully. Maintain the moisture in your tree.

INPUT ARTICLE: Article: It can be difficult to maintain small portions or not snack when you feel hungry.  However, it's also important to understand and define what true physical hunger is.  You may feel "hungry" when you're bored, stressed or angry and be tempted to eat.  Physical hunger comes on gradually.  In addition your stomach may feel empty or growl or make noises.  Physical hunger also goes away after even a small portion of food.  If it's been several hours since your last meal or snack, you may be physically hungry.  Eat your planned snack or meal. If you notice that you're feeling "hungry" without the signs of physical hunger, consider the other reasons you may be craving foods. Remember, feeling hungry is OK.  You should feel hungry before your meal and you might feel hungry at bedtime.  This is normal and expected. It can be easy to eat in the car, during a work meeting or while watching TV.  Sitting down to eat will draw your attention to your meal.  This can help you stick to a smaller portion.  Take this a step further and disconnect from all technology.  Turn off the TV, computers and phones so you can fully pay attention to your meal. Set a rule that you only eat when you're sitting down at a table or desk.  This will help curb unnecessary eating or snacking. Take about 20 minutes or more to eat your meal.  This is about the time it takes for your brain and stomach to communicate that you've had enough to eat and you're satisfied.  Promote an environment that is solely used to eat. Avoid snacking while working or watching TV. Sit down to a meal and don't get up until it's done. Really savor your food and dedicate a specific meal time to you. You will appreciate your meal more and feel more full as you enjoy each bite. Set a timer or a stop watch to give you an idea of how much longer it should take you to eat. Put your fork down in between each bite, take a sip of water between each bite or chat with friends or family as you eat. Take small bites and chew each bite at least 20 times to slow you down.

SUMMARY: Write down your definition of hunger. Sit down to eat. Eat slowly.
