Article: 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.
Question: What is a summary of what this article is about?
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.
Article: Avoid deciding that your group will need a designated driver after the first round of drinks. It is very dangerous to decide who will be the designated driver based off of the person who is the least drunk or has had the least to drink. It is wise for the designated driver to remain sober the entire night. Although it is legal to drive with a blood alcohol content of .08, unless you have an accurate breathalyzer, it is wise for the designated driver to completely refrain from drinking. To avoid any disagreements or fights while you are intoxicated, give your keys to your designated driver before you start drinking. Instruct the designated driver to not return your keys to you until you are sober, even if you adamantly request them.
Question: What is a summary of what this article is about?
Select your designated driver before you begin drinking. Confirm that the driver will not consume alcohol. Give the keys to the driver before anyone drinks.
Article: Containers come in several grades, which provides information about how the container was used before it went up for sale. What grade you needs depends on what you need it for.  "New" or "one-trip" containers have typically been made in China and then shipped directly to the United States. If you want to convert your container into a home, this is the best option, as it will be weather resistant, and have the least damage. "Cargo-worthy" containers have been used a bit more, but are still in good condition, and could be used at sea again. Typically these will be wind and water tight, and, structurally speaking, would still be able to handle being shipped overseas.  "Wind and water tight" containers are those that are still able to keep out the elements, but have not been officially inspected in order to be declared “cargo-worthy”.  "As is" containers are those that may or may not be able to stand up to the elements, and may or may not have structural damage. Different containers are made of different materials. All containers that were used for overseas shipping are made of steel, and are much stronger than their aluminium counterparts. If you wish to live in the container, you will need to purchase a steel container, as these are much stronger and more durable (they were made for trips across the ocean, after all). However, if you only need it for a temporary storage solution, and aren’t worried about the weather, an aluminium container could suffice. Containers also come in various sizes. You may want a larger or smaller container depending on what you need it for.  Containers range in length from 20 feet (6 meters) up to 53 feet (16 meters).  They range in height from 8 feet 6 inches (2.6 meters) up to 9 feet 6 inches (2.9 meters).  Width ranges are between 8 feet (2.4 meters) and 8 feet 6 inches (2.6 meters) Some containers will come in a plain color, while some may have the logo of the company that used them for shipping goods. If you plan to repaint the container, it doesn’t matter much. However, if you don’t plan to repaint it, you should choose a container with a color and/or design you don’t mind looking at. Some containers, for example, might have been used to transport goods with a very strong odor, such as animal hides. In this case, you may end up with a shipping container that is contaminated by a strong, foul odor.
Question: What is a summary of what this article is about?
Find the right grade. Decide between steel or aluminium. Choose a size. Consider the outside of the container. Consider what the container was used for.
