Article: Gently clean the exterior of the chaga with your hands or a soft-bristled brush. Make sure there are no insects or residual tree bark left on the chaga, or else it could develop mold. Larger pieces of chaga will take longer to dry out and could possibly develop mold. Use a knife to cut the chaga into pieces so they will dry out more efficiently.  The pieces do not need to be uniform in shape, but they should be relatively similar in size. You can cut the pieces thinner if you want them to dry more quickly. Try to use a grated tray so air can flow on all sides of the chaga pieces. Leave them on the windowsill for 3 days until they feel hard and dry.  Do not use the oven to dry out mushrooms. If you have access to a dehydrator, set the temperature to 120 °F (49 °C) or lower to dry the mushrooms. Dump all the pieces of the chaga into the jar and keep it in a cupboard or closed pantry. Chaga can be stored throughout the year.  Most times, 1 grapefruit-sized portion of chaga will be enough for a full year unless you use it multiple times a day. The chunks can be ground into a powder with a mortar and pestle after they have been dried.
Question: What is a summary of what this article is about?
Remove any tree bark from your chaga. Break chunks of chaga into pieces 1 by 1 in (2.5 by 2.5 cm) or smaller in size. Place the pieces on a tray on a sunny windowsill to dry them. Store the pieces in an airtight glass jar in a dark place for up to 1 year.

Problem: Article: Nuts and bolts should regularly be examined to ensure that they are not loose. It's important to check that the nuts that attach your wheels to the axl are securely fastened. These nuts should be tightened to the point where they can no longer turn (but not hinder the ability for wheels to move). You should tighten these bolts with a Phillips Head Screwdriver or a Socket Wrench. These are the metal pieces that keep your wheels in place and they are secured by the kingpin bolt. Turn your board upside down, and adjust the nut in the middle of each truck counter clockwise with a half of a quarter turn to tighten it. The tighter your kingpin bolt, the more security you will have when skating. If you are a beginner, keep those trucks tightly bolted. If you are unsure about how to adjust your trucks by maneuvering the kingpin bolt, visit your local skate shop with your board, and ask them to show you. Whether you're a professional skater or a novice to the sport, protective gear is essential if you want to skate safely. Wearing a helmet might not earn you cool points, but it will keep you safe and even protect you from getting a concussion if you fall and land on your head. It's best to protect all areas that are exposed, including your head, knees, and wrists.  Wrist pads, gloves, knee pads, and helmets are a good place to start if you want to purchase protective gear. They won't stop you from skids and falls, but they will protect exposed parts and prevent more serious injuries. Helmets should have a buckle strap and fit around your head snugly. Be sure to get a helmet that is specifically made for skateboarders.
Summary: Safety check your board before riding it. Adjust the trucks. Wear protective gear.

INPUT ARTICLE: Article: This method will work best on shoes that are made completely out of canvas, such as Vans and Toms. If you have a pair of shoes that lace up or have a rubber toe cap, try this method instead. Here's a list of what you'll need:  Canvas sneakers Bleach Water Plastic tub Rubber gloves If your sneakers have inserts inside, you can pull those out and set them aside. This way, they will be their original color when you put them back in. This can create a nice contrast. You want to protect your hands from the bleach solution. For a stronger solution, use one part bleach and one part water. For a weaker solution, use one part bleach and two parts water.  The water-bleach solution needs to be deep enough so that you can submerge the shoes completely. The plastic tub needs to be long enough so that you can sit your shoes inside. Try to set them upside down in the tub. This way, more of the fabric gets covered with bleach. This will take one to five hours, depending on how dark the shoes are to begin with, and how light you want them to become. Keep in mind that some of the darker colors will never fully turn white. Some colors, such as black, will turn orange or brown. Be sure to check back on the shoes every 10 to 60 minutes. This will stop the bleach from acting. It will also get rid of the smell. It will take about three hours for them to fully dry.

SUMMARY: Gather your supplies. Consider removing the inserts. Put on a pair of rubber gloves. Fill a plastic tub with bleach and water. Place your sneakers in the plastic tub. Leave the sneakers in the tub until you get the desired effect. Take the shoes out of the bleach solution and wash them using soap and water. Let the shoes dry before lacing them back up.

In one sentence, describe what the following article is about: You’ll need to be in the Arctic Circle to see the northern lights, and the winter months between November and March are the best time to see them because of how dark it gets. Some places you can go to photograph the northern lights are Iceland, northern Canada, northern Alaska, and the northern region of Sweden, Norway, and Finland. Light from nearby buildings will make it harder to capture the northern lights on camera. Once you pick a country to photograph the northern lights in, find a place there that’s far away from human activity. If you need help finding a good spot that doesn't have a lot of light pollution, check out the Blue Marble Light Pollution Map at https://blue-marble.de/nightlights/2012. Abisko National Park in Sweden is a spot in the path of the northern lights that’s far away from light pollution. You won’t be able to photograph the northern lights if there is a lot of cloud cover. Try to go out shooting on a night when there’s 0-10 percent cloud cover. If the cloud cover is 20-30 percent, you may still be able to take some photos of the northern lights, but they won’t be as clear. Check the local weather forecast to find out what nights during your trip will have the clearest skies for your photo shoot. The Kp-index measures the amount of auroral activity there will be on any given night. The more auroral activity on the night of your photo shoot, the more likely you are to see the northern lights. To check the Kp-index, visit http://www.swpc.noaa.gov/products/planetary-k-index. You should be able to see the auroral activity for that day and the day after. Auroral activity is measured on a scale of 0-9, with 0 being no activity and 9 being a significant amount of activity. If the Kp-index is 4 or higher for a particular day, you should be able to see the northern lights.
Summary: Plan a trip to the Arctic Circle sometime between November and March. Choose a spot with minimal light pollution. Pick a night when the forecast calls for clear skies. Check the Kp-index before your photo shoot.

Some of the questions require extreme precision and timing with your cursor or touch screen. If you're on a laptop, plug in a mouse instead of relying on your mouse pad. The game lets you earn "Skips" which can be used to skip some questions if you get stuck, but don't be tempted! It is impossible to beat the game unless you have all seven "Skips" unused on question 110 (the last question). A list of numbers is written on the screen on question 50.
