What is the central idea of the section titled "Heard the News?" A. A breakthrough in hearing aid technology was inspired by a certain fly's extraordinary hearing capabilities. B. Researchers are facing a challenge in trying to mimic a fly's hearing abilities because of the insect's complex ear structure. C. There are limitations to a certain fly's hearing capabilities, and it may not be practical to make high-tech devices based on its anatomy. D. Scientific contributions to fly-inspired technology are leading to researchers studying uses beyond hearing aids, such as sound sensors and radar systems.Read this sentence from paragraph 2. The small difference in time that it takes to activate the other eardrum allows the fly to figure out which direction the sound is coming from with remarkable accuracy. Which phrase gives this statement a subjective point of view? A. "it takes to activate the other eardrum" B. "allows the fly to figure out" C. "which direction the sound is coming from" D. "with remarkable accuracy"

Can a Fly Help Humans Hear? Heard the News? 1) This might make your ears perk up. Researchers at the University of Texas at Austin's Cockrell School of Engineering experienced a major breakthrough with their research on hearing aids. The team had created a tiny, low-power device that mimicked the Ormia ochracea fly's extraordinary hearing capabilities. 2) This yellow-colored fly has two separate ears with eardrums connected to each other by a joint. The joint is rigid but can move like a seesaw (Campbell). When one eardrum vibrates from a sound wave, it pushes the other eardrum. The small difference in time that it takes to activate the other eardrum allows the fly to figure out which direction the sound is coming from with remarkable accuracy. Scientists call this directional hearing- High-Tech Hearing Aid 3) The Cockrell School research team developed a gadget that, at two millimeters, is nearly identical in size to the Ormia's hearing organ (University of Texas at Austin). Inspired by the fly's seesaw-like ear structure, the device includes a flexible beam with electric components. It's made of silicon and is pressure sensitive, just like the fly's hearing structure. What's more, it turns pressure into electric signals, which allows the device to operate with little power (University of Texas at Austin). 4) This new technology can be used to make more powerful hearing aids, which may be a boon to the hearing impaired in the future. Currently, 2 percent of Americans use hearing aids, but doctors believe that 10 percent of the population could benefit from them (Bardi). Developing Sensors 5) Researchers at the University of Toronto at Scarborough took the research done by Cockrell School scientists a step further. They focused on how the Ormia is tiny relative to the sound waves that it detects (Campbell). That the fly is able to process such huge sound waves and determine their direction is extremely impressive. The scientists wanted to develop artificial sensors based on the Ormia's eardrum structure that could determine the direction of sound waves, even ones that are so large their origin can be difficult to pinpoint. The uses of this technology wouldn't be confined to hearing aids. From sound sensors to radar systems, the technology could have multiple uses. 6) Scientists believe that the Ormia fly still has a lot to teach humans about hearing capabilities. As they develop high-tech devices based on the insect's anatomy, they'll continue to study the creature. Keep your ears peeled for new developments! Works Cited 7) Bardi, Jason.
