If possible, describe any solution proposed in the text.57 sentencesA Device That Easily Opens BottlesTo find a solution for her grandmother, Aasritha explored what kinds of bottle-opening devices already existed, and then she created her own.For the improved bottle opener design, Aasritha used a piece of wood shaped like a cellphone. "The rectangular shape and size of a cellphone is familiar," she said.Next, she put three holes in the wood. The holes were different sizes, so that they could match common bottle cap sizes. Each hole also had a layer of dried, sticky hot glue. The glue layer provided a firm grip for the bottle caps. With a simple twisting motion, her grandmother could open bottles without assistance.Students like Aasritha used math, physics and tool skills to address challenges people face, such as movement disorders. The students also learned about empathy."Empathy is looking at problems from another's perspective," Aasritha said. Her teacher, Mark Bolt, said it's another important part of engineering because engineers need to put themselves in the shoes of the person using the product.
Based on the article, which is most likely to happen?A.Dr. Aszmann will no longer perform bionic reconstructions.B.New prosthetic hands will soon be manually operated.C.Milorad Marinkovic will ask that surgeons improve his bionic hand.D.More people will undergo bionic reconstruction surgery.Milorad Marinkovic, age 30, lost the use of his right hand in a motorcycle accident in 2001. He never thought he'd be able to control a prosthetic as naturally as he controlled his unaffected hand. Neither did his doctors. But in 2011, Marinkovic replaced his injured hand with a bionic one. It responds to thought, just as a natural hand does.The patients then needed to learn to use faint signals from those nerves to command the artificial hand. Now, the men use their new, bionic hands to perform everyday tasks. They can pick up a ball, handle small items like coat buttons and shoelaces, and cut food with a knife.Previously, people with bionic hands have primarily controlled them with manual settings. But with the new groundbreaking technique, the transplanted nerves allow the brain to relay messages directly to the new extremity. It's particularly notable since the human hand contains sophisticated muscle structures and a complex nerve system, making it especially difficult to copy.Dr. Oskar Aszmann of the Medical University of Vienna developed the bionic reconstruction approach with some of his coworkers. He performed the first surgery in April 2011 on an Austrian named Patrick, then age 24. (Patrick declined to give his last name.) He had lost the use of his left hand as the result of a work injury three years earlier."This is the first time we have bionically reconstructed a hand," Dr. Aszmann said at the time. "If I saw these kinds of patients five to seven years ago, I would have just shrugged my shoulders and said, 'There's nothing I can do for you.'"Aszmann's team described the cases of the three men in a report published in the journal Lancet in February 2015. All three men had suffered injuries to the brachial plexus. This is a network of nerves running from the spine to the shoulder, arm, forearm, and hand, and it controls movement in these areas.Injuries had left the hands of these men paralyzed. They opted to undergo the elective amputation only after having the bionic hand strapped onto their injured hand. This allowed them to see how the robotic one might work.Now, after the surgery, Marinkovic loves his new hand. It allows him to hold things like a sandwich or a bottle of waterand most importantly, to play with his three children. Still, the bionic hand is not the same as a natural one.Not C I got that wrong!
