Text 1 Many visually impaired people can't see words written on a page. Instead, they use a tactile writing system called braille to read. Individuals with visual impairments use their fingers to feel what is written instead of reading with their eyes. In order to print books, letters, and other documents in braille, though, you will need a braille printer. This device works like a laser or an ink jet printer. Firstly, this device works if you have installed a braille translation software on a computer. Then you have to connect the printer to your computer. The translation software will translate the document on your computer into braille code. After that the printer will receive the data that tells it what to print. Inside the printer are a series of embossing pins that create the indentations in the paper. After receiving the code, the printer will hammer out dots on thick paper using cylindrical coils of wire called solenoids to move the pins. Braille printers use social paper that is heavier than standard printer paper. They are also louder and slower than printers used to print visual media. Printed braille takes up more space on the page than written letters, so printers may require more paper for the same document. (1) Braille printers are different from braillers. (2) Braillers are like braille typewriters. (3) The cost of a braille printer depends on how much it is designed to print. (4) They have six keys for each of the six dots used in braille and a few other keys for things like line spacing. (5) Some braillers have a special bell that lets blind.people know when they are only a few spaces ahead of the end of a line. (6) Some braillers are purely mechanical and don't require electricity to work. (7) Others can be plugged into the wall. Adapted from: https://www.webmd.com/eye-health/what-to-lmow-about-brail/e-printers Text 2 After his stint in the French Royal Army from 1784 to 1792, Charles Barbier de Ia Serre had become very interested in literacy. He wanted to make it easier for people including the blind- to learn to read and write, and he thought the best solution was to offer them a simpler writing system. Barbier tinkered with several options over the years, ranging from shorthand to a phonetic alphabet. Eventually, he developed a system that arranged letters in a grid. Each letter would be represented by two numbers, which in turn could be written as two rows of dots. By counting the dots, a person could read the numbers and then convert them to the right letter. It was a bit clunky, but it meant that a blind person could read the raised dots by feel - and then make impressions on a piece of paper, which another blind person could read the same way. He brought his grids and dots to the Royal Institution in 1821, and one of the first students to learn it was the then 12-yearold Braille. Braille immediately realized the potential Barbier's system offered, but he also saw room for improvement. He took the idea and ran with it, essentially, and spent the next several years developing a simpler, more flexible version of Barbier's raised-dot alphabet. The writing system that 'thousands of people still use today - and millions more relied on before the advent of smartphones - began as a teenage boy's school project. He finished by 1824, but had to wait until1829 to actually publish the first edition of what's now known as braille. But the version he published in 1837 is the one still used today: neat arrangements of between 1 and 6 dots to represent each letter. It even included notations for music, since Braille was an accomplished cellist and organist as well as a star student and a language developer.

As a researcher, I'm especially intrigued by fungus-growing ants, a group of 248 species that cultivate fungi as their main source of food. They include 79 species of leafcutter ants, which grow their fungal gardens with freshly cut leaves they carry into their enormous underground nests. I've excavated hundreds of leafcutter ant nests from Texas to Argentina as part of the scientific effort to understand how these ants coevolved with their fungal crops. Much like human farmers, each species of fungus-growing ant is very particular about the type, of crops they cultivate. Most varieties descend from a type of fungus that the ancestors of fungusgrowing ants began growing some 55 million to 65 million years ago. Ant farmers face many of the same challenges human farmers do, including the threat of pests. A parasite called Escovopsis can devastate ant gardens, causing the ants to starve. Likewise in human agriculture, pest outbreaks have contributed to disasters like the Irish Potato Famine, the 1970 corn blight, and the current threat to bananas. Since the 1950s, human agriculture has become industrialized and relies on monoculture, or growing large amounts of the same variety of crop in a single place. Yet monoculture makes crops more vulnerable to pests because it is easier to destroy an entire field of genetically identical plants than a more diverse one. Industrial agriculture has looked to chemical pesticides as a partial solution, turning agricultural pest management into a billion-dollar industry. The trouble with this approach is that pests can evolve new ways to get around pesticides faster than researchers can develop more effective chemicals. It's an arms race-and the pests have the upper hand. Ants also grow their crops in monoculture and at a similar scale-after all, a leafcutter ant nest can be home to 5 million ants, all of which feed on the fungi in their underground gardens. They, too, use a pesticide to control Escovopsis and other pests. Yet, their approach to pesticide use differs from humans' in one important way. Ant pesticides are produced by bacteria they allow to grow in their nests, and in some cases even on their bodies. Keeping bacteria as a living culture allows the microbes to adapt in real time to evolutionary changes in the pests. In the arms race between pests and farmers, farming ants have discovered·that live bacteria can serve as pharmaceutical factories that can keep up with ever-changing pests. Whereas recent developments in agricultural pest management have focused on genetically engineering crop plants to produce their own pesticides, the lesson from 55 million years of ant agriculture is to leverage living microorganisms to make useful products. Researchers are currently experimenting with applying live bacteria to crop plants to determine if they are effective at producing pesticides that can evolve in real time along with pests.

A tribute to childhood memories: The story of memories from her life around 2019 " This is my story, They recognize me but they like me... They often...look at me I often liked other boys and other girls after I graduated in May 2019. " " For making my life kindly...

Because I often see this boy suddenly get injured on his head and face... Feelings of trauma and guilt until I was shocked and I didn't understand. " " Because of that, my family told them that he was not a brain dead, he was just injured. Or he was in a coma for 3 months. " " The police have been investigating the accident since April.

Until he was adopted by another boy he have a blonde hair too like my older siblings in 2004." " After that... They often laughed at me with my behavior of not having trivial problems... And they often like to touch me. " What is the title of the tribute written above? A. Organ donation B. The story of memories from her life around 2019 C. The story of his parents' teenage years

What's the main idea and supporting details from this text? PLASTIC POLLUTION Around the world, people throw away roughly four million tons of trash every day—that's enough to fill 350,000 garbage trucks or 10 Empire State Buildings. About 12.8 percent of that waste is plastic, which causes big problems for wildlife: some animals mistake plastic for food, while others can become entangled in the trash. Tips to Reduce Waste! 1. Don't use face wash or toothpaste with microbeads. These tiny plastic beads go down the drain, eventually making their way to rivers, lakes, and the ocean at a rate of eight trillion a day in the United States. Because these toxic beads look a lot like fish food, it's not uncommon for bigger fish and sea turtles to munch on them—a dish that could be deadly. 2. Say no to straws! In 2015 a viral video showed an olive ridley sea turtle in obvious discomfort as a team of experts work to dislodge something deep within its nostril. At first, they thought it was a worm. But experts were stunned to see what it really was: a plastic drinking straw. 3. Instead of packing your sandwich and snacks in plastic bags, use reusable containers or cloth sacks instead. Same goes for your drink: Skip the juice boxes and opt for a refillable water bottle. 4. Reduce the amount of plastic bags clogging up our trash and oceans by shopping with reusable bags instead. 5. To eliminate some of the excess packaging piling up in landfills, encourage your family to shop for snacks, cereal, and pasta in the bulk section of your grocery store (if yours doesn’t have any bulk items, check out a nearby natural food shop). Then, store it all in reusable glass jars. 6. Pack an apple, a banana, or an orange. Fruit fills you up in a healthy way, plus there’s no need for extra packaging. (Save the core, peels, and rinds for your compost bin.) Using these tips, keep track of the trash you toss. Every week, try to throw out less and less and see how much you can minimize your waste in a month. Some people have managed to put an entire year’s worth of garbage in one jar. Can you beat that? If your family is like many in the United States, unloading the week’s groceries includes hauling a case or two of bottled water into your home. On your way to a soccer game or activity, it’s easy to grab a cold one right out of the fridge, right? But all those plastic bottles use a lot of fossil fuels and pollute the environment. In fact, Americans buy more bottled water than any other nation in the world, adding 29 billion water bottles a year to the problem. In order to make all these bottles, manufacturers use 17 million barrels of crude oil. That’s enough oil to keep a million cars going for twelve months. Imagine a water bottle filled a quarter of the way up with oil. That’s about how much oil was needed to produce the bottle. So why don’t more people drink water straight from the kitchen faucet? Some people drink bottled water because they think it is better for them than water out of the tap, but that’s not always true. In most places in the United States, local governments make sure water from the faucet is safe. There is also growing concern that chemicals in the bottles themselves may leach into the water. People love the convenience of bottled water. But maybe if they realized the problems it causes, they would try drinking from a glass at home or carrying water in a refillable steel container instead of plastic. Plastic bottle recycling can help—instead of going out with the trash, plastic bottles can be turned into items like carpeting or cozy fleece clothing. Unfortunately, for every six water bottles we use, only one makes it to the recycling bin. The rest are sent to landfills. Or, even worse, they end up as trash on the land and in rivers, lakes, and the ocean. Plastic bottles take many hundreds of years to disintegrate. Water is good for you, so keep drinking it. But think about how often you use water bottles, and see if you can make a change. And yes, you can make a difference. Remember this: Recycling one plastic bottle can save enough energy to power a 60-watt light bulb for six hours. Mohon bantuannya kakak² dan teman-teman 🙏
