In one sentence, describe what the following article is about: Since backpacks can feel heavier the longer you wear them, find a pack with padded straps. Look for bags that have thick, breathable pads on the straps so you don’t get too warm while you’re carrying it. Try on the bag and carry it around to see if the pads are comfortable on your shoulders. If possible, get a bag with hip straps to help take some of the weight off of your shoulders. Look for backpacks that are made of durable materials, such as high-quality nylon or polyester, so your bag doesn’t break. Check the zippers and straps to make sure the seams are sewn tightly since they are the first areas to usually break. Look at the packaging to see what the bag is made of so you know what to expect from your bag.  Make sure the backpack is waterproof so your things don’t get wet. If your bag isn’t waterproof, you can always buy a rain shield to cover your backpack.  Some backpacks may have a lightweight frame to maintain the structure of your bag. The back panel is the part of the bag that rests against your body and adds support. Look for bags that have a curved back panel rather than a flat one so it fits comfortably on your back. Make sure the back panel has ventilated foam or is made of breathable material so you don’t get sweaty while you’re carrying your backpack.   Many back panels also have a carrying strap so you can put your bag on the handles of your other luggage. Some specialty bags may have a storage compartment in the back panel. Some travel backpacks have wheels on the bottom so you don’t always have to carry them on your back. Get a wheeled backpack if you want to comfortably travel with it and take the weight off of your shoulders. These backpacks also usually have front-loading zippers so your things are easy to access. Rolling backpacks may take up more space and weigh more due to their wheels.
Summary: Get a backpack with comfortable padded straps for the best support. Choose a light and durable backpack so it lasts for a long time. Find a backpack with an ergonomic, ventilated back panel. Use a wheeled travel backpack to make transporting the bag easier.

If your Android device doesn't support screenshots, you may still be able to take screenshots using an app. Open the Google Play Store and search for "Screenshot". There are lots of different free screenshot apps you can try out.
Summary: Press the screenshot buttons. Find your screenshots. Use a screenshot app for older devices.

In one sentence, describe what the following article is about: Your classmates are ideal sources for helping you understand your homework, especially those who already completed the assignment or excel in the subject. You can ask your classmates for clarification on the instructions or for help in understanding the material itself.  Nowadays, it shouldn’t be too difficult to contact a few classmates through social media or texting. If you’re too young for social media accounts or your own phone, you can ask a parent to call one of your friends’ houses, instead.  For help with the instructions, you’ll usually need to ask someone in your class. For help with the material, however, you might also be able to ask friends in another class who are covering the same information at the same time; in fact, their teacher may have presented the information from a different perspective, allowing them to introduce that fresh perspective to you, too. For bigger assignments, you might even try organizing a study group for the homework assignment. Some institutions may offer a learning center or writing center where you can be tutored by teaching assistants or fellow students. Search your university or school's web page for more information.  Some schools and universities offer special tutoring programs for athletes, first generation college students, or other groups. If you're uncertain where to find information, ask a librarian. They can often point you in the right direction. Don't forget to ask your professors, teachers, and classmates about where you can get additional help. If you aren’t able to get help from your classmates, older siblings and cousins can be your next best option, especially if they’re only older by a year or two. The information should still be somewhat fresh in their minds--they may even use the same principles in their current grade level assignments--so they might be able to answer any questions you have about the material. You might also consider asking relatives who are the same age as you. It’s possible that they’re covering the same material now, or that they’ve covered it a few weeks sooner than your class has. While the information may not be as fresh in their minds as it would be for a sibling or cousin, your parents will still know a lot, especially if you’re learning information they use regularly or learning about a subject they enjoy. You can ask other members of your extended family, too, such as aunts, uncles, and grandparents. Some individuals are better than others at certain subjects, and might be able to explain your homework and the subjects you’re studying in a way that helps you understand them better. For example, if you’re struggling with English, ask family members who love to read if they can help you understand your assignment. This option won’t be available to everyone, but if you have access to a private tutor or if your school has a tutoring center, you should definitely consider asking them for clarification on the homework material. They should be willing and able to help; after all, a tutor gets paid to help students.  Send an email or call your tutor if you have a question but aren’t scheduled to meet with them the evening you have it. You can also ask your tutor if they have any advice on an assignment that isn’t related to the topic they tutor you for--e.g., you might ask your chemistry tutor for help on a math problem. The worst that can happen in either scenario is that your tutor will say they are unable to help you. If your instructor has provided your class with an email address, and you’ve exhausted your other options, consider sending them an email asking for clarification. Try to be as specific as possible when explaining what part you don't understand, whether it deals with the instructions or the material itself, and ask direct questions that can clarify your confusion.  For instance, you might type, "I'm confused about which problem set I need to do. I thought you said the problems were on page 86 of the textbook, but there aren't any problems on that page." Understand that your teacher may not be able to respond right away. Even if they don't, you've at least communicated your desire to understand to your teacher, which may encourage them to spend more time on the material in future class sessions.
Summary:
Ask for help from classmates. Look up university or school resources. Check with your siblings or school-aged relatives. Ask for help from your parents. Consult a tutor. Email your teacher.
