[Free] How often should the water-handling components of an ice machine be cleaned? A. The water-handling components of an ice machine don't need cleaning. B. Monthly C. Weekly D. Annually

[Free] After being hit by a vehicle, why will a child have a different pattern of injuries than an adult who was struck in an identical situation? A. An adult will, more often than not, attempt to turn and outrun the oncoming vehicle, causing tremendous injuries to the posterior once struck. Children will generally attempt to jump out of the path of the vehicle and will sustain the majority of injuries to the side of the torso and legs. B. Children will normally turn their backs to an oncoming vehicle, thereby sustaining more serious back and head injuries. The adult, conversely, will turn and face the vehicle before impact. C. Children will usually drop to the ground in an attempt to avoid the collision, thereby sustaining more crush injuries. Adults, on the other hand, tend to leap up onto the hood of the oncoming vehicle, causing head and spine injuries as they strike the windshield. D. Adults tend to turn away from the impact, causing more injuries to the side of the body, whereas children will face the oncoming vehicle and sustain frontal injuries.
