Answer:
1. A; 2. D; 3. A; 4. D 5. B
Step-by-step explanation:
1. The first thing to consider in any environment that involves a form of physical exercise is to ensure the place is safe for such an exercise. This is because any misstep during the course of an exercise can lead to serious injury in a wrong environment, whereas a right and safe environment can prevent such or at the very least mitigate the effect. Dancing can be a form of exercise and as such ensuring the place is safe for dancing is critical and should be checked first. Thus, correct option is A.
2. A sprain can be defined as a painful injury to the joint. Having a mild sprain means the joint isn't very painful but still painful. However, to prevent further wrenching of the ligament which causes the pain in the joint, the affected individual must take a rest so as to allow the joint to heal. Jessie failed in allowing the injury to rest by continuing to join the dance competition. Thus, the correct option is D.
3. Before any physical exercise, it's important for a warm-up exercise to be done first. This is to stretch the muscles of the body and "get" the joints for further and more intense activities. Thus, the correct option is A.
4. In order to prevent injuries, it's important for every individual who takes part in any form of exercise to be guided by safety precautions, regardless of supervision. Thus, in the presence or absence of teachers, students must ensure to adhere strictly to safety precautions. The correct option is D.
5. Joining an exercise group (in this case dancing) for the first time might be challenging. This is usually due to the poor or wrong fitness of the new person (in this case Vina). This is an hazard on its own and it also affects performance. Thus, correct option is B.
