Soraya is being cyberbullied by a group of girls on social media. They have made several posts directly mentioning her and calling her hurtful names, along with making fun of her appearance and her cultural background. Which of the following would be the most appropriate way for Soraya to handle the situation?

A. Confront the girls at school and tell them she is ready to defend herself physically if they continue
B. Delete the social media accounts where she is being cyberbullied but take screenshots to show someone she trusts
C. Respond to the girls on her social media accounts with argumentative and emotional comments
D. Withdraw from friends and family until they notice something is wrong and help her with the situation​

Answers

Answer:

B. Delete the social media accounts where she is being cyberbullied but take screenshots to show someone she trusts

Explanation:

Best option is B because it does not involve physical altercation or any indications of possible physical altercation. Option B also allows them to keep evidence for future if needed.

Option A could end in a physical altercation such as fights which could put both Soraya and her bullies in trouble.

Option C will only cause the bullies to mock Soraya more as she starts arguments with them (remember the elephant keeps walking as the dogs keep barking.) So if Soraya does not engage with them they will likely go away but if she engages with them they bark back loudly.

Option D is very unhealthy option for Soraya as it could create mental health issues as well as problems in her family such as misunderstandings and such.

D. Continue practicing without the permission of the teacher

2. Jessie is still suffering from his mild sprain but still continued to join the dance competition. Which of the following is the safety precaution that he didn't consider?
A. Inexperience
B. Poor Posture
C. Hazardous environment
D. Failure to rest an injury

3. What is the first thing to do before you start any physical or dance activity?

5. Vina finds it hard to cope up with basic steps being taught by their teacher because it is her first time to dance. What is the hazard that affects her performance?
A. Overtraining
B. Poor Fitness
C. Inexperience
D. Hazardous Environment​

Answers

Answer:

1. A; 2. D; 3. A; 4. D 5. B

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.
