Read this excerpt from "heads up on sports safety.” the dangers to your head depend on the sport, but some general principles guide helmet design. first, the helmet needs to be as cool and lightweight and comfortable as possible. second, the helmet needs to be hard enough and fit well enough to protect the skull and brain. for some athletes, like hockey goalies or baseball catchers, the helmet also needs to protect the face from fast pucks or balls. third, it must not prevent the wearer from seeing or hearing. fourth, it cannot cause more injuries than it prevents. it turns out that the way to address many of these concerns is to use hard but flexible, light, strong materials on the outside and soft materials on the inside. scientists create new plastics all the time, but sometimes the best designs come from using old materials in new ways. one recent design makes the shell of helmets out of kevlar, the same kind of light plastic used in bulletproof vests. which is a key detail that supports the main idea that there are general principles that guide sports helmet design?

This thinning would materially change the sound of the drum, evidence that although it might continue to be used for its original purpose of music-making or calling people to arms, it would now do so with a different voice. a musical instrument had become a trophy, and the new carvings were in fact branding, a statement of the north’s political dominance over central africa and of allegiance to islam.the drum had come to khartoum at a critical moment in sudanese history. in an audio version, stressing the word "branding" would do what for the listener? emphasize the word's importance and the idea that followsadd emphasis to the following sentencesignal that something important has just been repeatedadd emphasis to the preceding sentence
