Your neck can also get hurt while playing football, so many helmet designers are using materials that prevent neck injuries. One common injury is whiplash, which is a sudden hit to the head that moves the neck very quickly. Neck padding can help, but materials that prevent the head from turning can decrease athletic performance. One alternative is to use a thermoplastic material that responds differently to different kinds of pressure. This material is soft when moved or pressed slowly but stiffens into a hard version of its shape when hit quickly. It has been used in bulletproof vests for at least a decade.
One problem and its solution presented in this article is

A. the possibility of whiplash and the use of thermoplastic material to prevent the neck from turning very quickly.
B. the efforts made by helmet designers to find new protective materials and the use of thermoplastic material to prevent neck injuries.
C. the fact that neck injuries can be hard to avoid and the occurrence of whiplash when the head moves quickly.
D. the probability of head injuries in sports and the use of bulletproof vests by athletes to stay safe.

Need asap pl the kite flyer fifteen-year-old kwan sat on a large boulder on the rocky shore and watched her seven-year-old brother, min, race along the beach close to the water’s edge. the handmade kite, streaming high in the air behind him, created a striking image against the vivid blue sky. occasionally, min called out, “kwan, look at me! i’m flying! i’m flying! ” she beamed and waved at him, urging him on in his glee. she recalled the day her parents first brought home the little bundle from the hospital, the first boy in the family, making her the happiest big sister ever. the family had had a new baby to care for and cherish, and she had a precious little brother to shower with love and attention. min brought joy and delight to the whole household, and his presence completed the family. kwan smiled again as she watched him run along, and she felt great contentment at the pleasure he took in flying the kite they had made together. ever since father had taken min to the korean kite festival, he had begged for a kite of his own. the multicolored dragons, birds, and box kites with their colorful tails and plumes appeared to enchant min as he watched them soar and race in the clear blue sky. he stood mesmerized by the panoply of colors. “someday, i will race a kite in the festival! ” min stated with determination. when min made up his mind that a kite would be the perfect summer project for him and kwan, she was surprised. “i don’t want a kite-making kit,” he informed their father. “i want to build it myself—with kwan’s .” kwan initially wondered why min included her in his quest for a kite, but she quickly realized that her clever brother had correctly surmised that their father would more likely approve the request if min’s big sister were there to him. how could kwan refuse? kwan gazed out at her brother and heard his shrieks of delight as he tried to direct their marvelous flying creation. she watched it wheel, spin, and dive—a wild, colorful bird putting on an aerial display. its gold and red crepe-paper wings fluttered in the air, mimicking the flight of a predatory bird surveying the landscape for prey. it swooped and dived, perhaps discovering a possible meal, and then went airborne again to avoid the rocky terrain below. min was the falconer, guiding his bird on its path through the sky, not yet ready to call it back to the ground. but kwan grew concerned when she looked out at the dark, threatening clouds beginning to roll in off the water. when she saw the streaks of lightning within the cloud formation, she pointed to the distant storm and called out to her little brother to bring in the kite. min nodded and rolled in the kite string, bringing his bird home. “let’s go,” kwan told her brother and put her arm around him to fold him safely under her wing as they both held onto the kite. “it’s time to go home.” how does the extended metaphor in paragraph 3 of the passage affect its meaning? a- it shows that min, like a bird of prey, can make the rest of the world bend to his will. b- it conveys the idea that the kite moves with impressive grace and majesty, like a bird of prey. c- it suggests that the kite, like a bird of prey, has great power and demands respect. d-it demonstrates that kwan is delighted with her little brother's excitement at flying the kite.
