Problem: Article: Getting enough sleep is the best way to make sure you stay awake in class. For most students, 8 hours is enough sleep to get them through the day, but you might need more depending on your energy levels. Going to bed at the same time every night will train your body to know when it should be sleeping and when it needs to be awake. Before you go to sleep, give yourself time to relax and unwind before bed, without phones, homework, or other stressors. In combination with regular exercise and healthy eating, getting enough sleep can alleviate most daytime fatigue problems. Maintaining good posture can keep you awake and your body alert. You can stretch a little in your chair to help you feel refreshed. Start by rolling your wrists, shoulders, and neck. You can make it a challenge to keep yourself from slouching. Every time you notice yourself beginning to slouch, adjust your posture and sit up straight. If you have a choice, sit in a chair or desk that is slightly uncomfortable to keep you from slouching. Physical activity tells your body that it's not time for sleep just yet. Walk around during breaks, go outside if you're allowed to, and get your blood moving to improve alertness. After you stop moving, you might feel tired again, but it can help for a little bit. If you're falling asleep in class, excuse yourself to walk to the bathroom and back. Even a short walk can wake you up. Take the stairs on your way to class. It can get your heart rate up and make you feel more alert.
Summary: Sleep for at least 8 hours each night. Sit up straight and stretch in your chair. Walk around before or after class.

INPUT ARTICLE: Article: Lavender plants, unlike many perennials, do not handle division well. Read the section on deciding how to propagate lavender for more advice, or refer to either section on cuttings instead if your main goal is to produce new lavender plants. Lavender plants are dormant during winter, although they may retain their greyish-green color. Wait until early spring to divide the plant, but do not wait until the plant begins the growing season in earnest. If the center of the plant is dead, you should be able to identify individual clusters of stems circling the dead area, attached to the same section of roots. Plan to divide the plant so each new section has at least three to five growing stems and roughly equal shares of the root base. This may require you to include multiple clusters in one division. As a rough guide, each hole should be about twice as wide as the root ball, and approximately 12 inches (30 cm) deep. Keep in mind that these root balls will be smaller after division. Organic material such as compost or pine bark can be mixed into your garden soil to use as backfill, or the material can be placed in a layer about 3 inches (7.5 cm) deep at the base of each hole. Optionally, add a small amount of fertilizer high in phosphorus and potassium to the base of the hole as well. If the plant is not excessively large, the center is not dead, or separate divisions are not easily visible while the plant it is in the ground, you may wish to remove the entire plant before dividing it. Otherwise, remove portions of the soil around the plant to increase visibility and access to the root ball. Pry down on the handle of the shovel as you move around the plant until the plant releases from the ground. Most lavender plants cannot easily be pried apart, but if your variety grows discrete clusters, you may attempt to pry them apart with two garden forks. More commonly, you will need to use a clean, sharp shovel to cut the lavender plant as you decided above, then use garden forks to pry apart the entwined roots. Plant each new lavender plant to the same depth it was planted previously, gently tamping down the soil around it as you fill the hole. Water thoroughly after planting to encourage new roots growth and set the plant in the soil. Continue to care for the lavender as usual.

SUMMARY: Use this method only as a last resort. Divide in early spring. Identify areas for division. Dig holes for the divided plants. Add enriched soil to the bottom of the hole. Dig the lavender plant partially or fully out of the ground. Use a shovel to cut apart the root ball. Plant each section in its own hole.

In one sentence, describe what the following article is about: . For this modern updo, you're using the clip to create a pile of curls on top of your head. The clip won't be visible, and your curls will pile in the shape of a Rihanna-style fauxhawk. Awesome, right? If you don't already have curly hair, go ahead and curl it up. Tight ringlets look great with this style and will stay in place better. If you don't want to use a curling iron or hot rollers, curl your hair without heat using a t-shirt or make pin curls. You'll need to start the night before with wet hair. Get the clip ready by unsnapping it at the top and opening it wide. Close the clip close against your head to gather your hair in place, then snap it shut at the top. The tip of the clip should land an inch or two back from your forehead. Arrange your curls around the clip so the ends fall on either side of it to hide it from view. Use bobby pins to secure the curls in place to keep the clip hidden. Finish the look with hairspray.
Summary: Curl your hair Open the clip. Snap it shut to secure your hair. Pin curls around the clip to cover it.

In one sentence, describe what the following article is about: You will need white vinegar, water, an empty spray bottle, and newspaper. It's also a good idea to ventilate the area so the smell of vinegar does not become overwhelming. Distilled water works best, as it contains the lowest amounts of contaminants and minerals. While steel wool removes dirt and grime from your windows, the vinegar removes grease and oils. Using both will leave you with sparkling, streak-free windows. Fill a spray bottle with this solution. Make sure the solution is mixed thoroughly. If you don't like the smell of vinegar, you could add a few drops of essential oil to your solution to mask the smell. If you don't have vinegar on hand, you can use lemon juice in its place. Don't dilute it, just use straight lemon juice in place of the vinegar and follow the same steps. Evenly coat the window, but don't use too much. You don't want a dripping, sloppy mess. Do this systematically: start at the top left corner and work your way to the right, then move down and work from the left to right again. Newspaper cleans glass better than paper towels, which leave streaky marks. You may want to wear gloves, as the newsprint could stain your hands. If you missed any areas, scrub them with a bit of the damp newspaper. Don't spray the solution directly onto the window, as you would likely have to clean the entire window again. If you still have streaks on your windows, mix 2 cups (470mL) of water, 14 cup (59mL) of vinegar and 12 teaspoon (2.5mL) of dish soap in a spray bottle. Spray the window and wipe it clean. This will help you catch any bits of dust or dirt left behind, and ensure your entire window area is clean. Enjoy your sparkling, streak-free windows!
Summary:
Gather your materials. Mix equal parts white vinegar and water. Spray the solution onto your window. Scrub your window with newspaper. Check for streaks or marks. Wipe down the window frame and sills.
