Problem: Write an article based on this summary: Select a variety appropriate to the climate. Consider the hardiness of trailing or training varieties. Consider the easy planting of upright, erect, or semi-erect varieties. Weigh the benefits of thornless berries.

Answer: The wild Himalayan blackberry is a tenacious invasive species in some parts of the western United States, but cultivated varieties tend to be juicer, larger, and more firm than wild berries. If you're going to plant some, it makes sense to pick one of these varieties, wherever you live, based on the structure of the cane, its growth pattern, and whether or not the variety has thorns. There are hundreds of strains and varieties to choose from, but knowing the basic categories will help you to make an informed decision.   If you live in a region with very cold winters, it's best to select an erect variety with thorns. These stand up to the elements the best and will provide the most solid-possible base for your climate.  If you live in a region with very dry windy summers, it's best to plant trailing varieties, which will stand up to the elements in especially harsh high-desert climates. Most varieties are able to grow in regions with at least 200-300 hours per season under 45 °F (7 °C), including USDA climate zones 7, 8, and 9 in the United States. Traditional training varieties grow much like the wild blackberry, shooting out suckers and sprawling all over the place, which means they'll need to be trellised with wires and trained along them to control the growth. Old fruiting canes will need to be removed, but new primocanes (new growth) will not need to be pruned. Trailing varieties often struggle in regions with especially cold winters, and won't fruit until their second year of growth. Evergreen, Marion, Obsidian, Chester, Hull, and Black Diamond are all popular varieties of trailing blackberry. These varieties of blackberry grow more like hedges, and will need to be supported with a T-trellis or a post of some sort. These varieties are easier to control and contain, but require vigorous pruning, shooting stiff new cane straight from the crown of the plant, rather than trailing along the ground. Many of these varieties will produce fruit in the first year of planting. Thorny erect varieties are the hardiest in cold climates. Illini, Kiowa, Shawnee, Apache, Triple Crown, and Natchez are all popular varieties of erect and semi-erect blackberry. Trailing, upright, and hybrid varieties are all now available in thorny and thornless strains, meaning that you can make your harvest a whole lot easier on your fingers. Thornless varieties do tend to be somewhat more sensitive to colder weather, making the thorny varieties a much hardier choice for most climates. Note that thornless varieties are more vulnerable to birds and other pests.


Problem: Write an article based on this summary: Take a pre-test. Review that morning -- if it calms your nerves. Get in the zone before class. Show up early. Do the easy questions first.

Answer: This is useful for two reasons: A) You'll be less nervous when the actual test rolls around (which can be rather detrimental to your grade) and B) you'll do better. A recent study at UC Berkeley showed that students who were tested on information they just learned actually did better than those who were asked to document what they were learning. So write up a pre-test and have your friend do the same! Then you can grade it for each other and reap the benefits. And if you can get your study group in on it, all the better. The more real it feels, the more prepared you'll feel and be when test day arrives. This is good for the exact same two reasons as stated in the previous step. You want to be as calm and relaxed as possible, and reviewing right before the test will do that. What's more, you'll retain the information (remember how the brain is clearer right when you wake up?). So on your way to class, whip out those flashcards for the last time. Only hit up the simple stuff (only revise simple concepts). Trying to wrap your brain around the large, difficult concepts when you have ten minutes on your walk won't do you any favors. You'll end up psyching yourself out -- the opposite effect of what you want! Just prime your brain for the content. Some people go so far as to meditate before class. Yoga helps, too! Anything that relaxes your breathing and gets you in the zone will be helpful. What would get you in the right place?  Consider listening to classical music. Though it doesn't make you smarter like some people (used to) believe, it can improve your memory. If you want to get super specific, listen to music that's 60 BPM. That's when the benefits will be highest.   Natural background noise generators that let you play rain, wind, water or a calm fire crackling have the same beneficial effect and help you getting in the zone. If you're running, running, running, you'll be stressed out, even if you know your stuff. Show up early, get out your materials, ask a friend questions (and have them do the same), slip in some gum, and settle in. It's time to rock this bad boy. An easy way to get stressed out and lose your cool is to focus on questions you don't know the answers to. You start worrying about the clock and thinking about how you didn't study enough. Don't fall into the trap -- move on to what you do know. Then you can hit the hard stuff dead on. The more time you spend on a question, the more time you risk second guessing yourself. You want to trust your intuitions. You worked hard! Never doubt yourself.Ensure that you revisit your work afterwards


Problem: Write an article based on this summary: Wipe the stain with a clean, damp cloth. Try a pencil eraser. Use toothpaste.

Answer:
If the ink or dye is fresh, then you may be able to remove it using just a clean, damp cloth. Try to wipe the dye or ink away in one motion, and then go back over the spot with a clean section of the cloth.  Use your fingertip to help you clean a small area. Wrap the cloth over your fingertip and use it to rub the dyed or ink-covered area. You can also try adding a small amount of dish soap to the water. Be sure to wipe the wall with water only after wiping it with soapy water. Use a clean, smooth cloth first and then try a more abrasive cloth or a sponge if that does not work. Don’t use an abrasive cloth if you don’t have to. Avoid using too much water when you wipe down your walls. Wet the cloth and then wring out excess water so that the cloth feels damp. A pencil eraser is a safe, gentle way to remove ink and dye stains from a painted wall without removing the paint. You can also control the area that you are cleaning more easily than some other cleaning methods.  Be sure to use a clean pencil eraser. Rub the pencil eraser gently over the dyed or ink-covered areas of the wall only. Apply a non-gel toothpaste to the stain and let it sit for 10 minutes. Wipe the toothpaste off with a damp cloth. Be careful not to rub the toothpaste too hard since it could spread the stain even more.
