Explanation:

Question 1 (List three physical benefits of physical activity)

Physical activity has several physical benefits. Some common ones include:

• a. Improved cardiovascular health: Regular physical activity strengthens the heart muscle, improves blood circulation, and can lower the risk of heart diseases such as heart attacks, strokes, and high blood pressure.
• b. Enhanced muscular strength and endurance: Activities like weightlifting, resistance training, or even bodyweight exercises (e.g., push - ups, squats) help build muscle mass and increase the ability of muscles to work for longer periods without fatigue.
• c. Better flexibility and joint health: Stretching exercises (e.g., yoga) or activities that involve a wide range of motion (e.g., dancing, gymnastics) can improve flexibility, reduce the risk of injuries, and keep joints healthy by increasing their range of motion.

Question 2 (List 4 mental and emotional benefits of physical activity)

Physical activity also has a profound impact on mental and emotional well - being:

• a. Reduced stress and anxiety: Exercise stimulates the production of endorphins, which are natural mood - lifters. It also helps the body manage stress hormones like cortisol, reducing feelings of stress and anxiety.
• b. Improved mood and self - esteem: Regular physical activity can boost self - confidence as individuals achieve fitness goals, and the release of endorphins can lead to an overall improvement in mood, making people feel happier and more positive.
• c. Enhanced cognitive function: Exercise increases blood flow to the brain, which can improve memory, concentration, and problem - solving skills. It also promotes the growth of new brain cells and helps in maintaining brain health as we age.
• d. Better sleep quality: Physical activity can help regulate the body's internal clock and reduce symptoms of insomnia. It tires the body in a healthy way, making it easier to fall asleep and stay asleep.

Question 3 (Give an example of social benefits of physical activity)

Physical activity often provides social benefits. For example, participating in team sports like basketball, soccer, or volleyball allows individuals to interact with others, build friendships, and develop teamwork skills. Joining a fitness class or a running club also provides opportunities to meet new people, share common interests, and be part of a community.

Question 4 (Explain the following statement: “The obesity epidemic is due to our sedentary society”)

In modern society, many people have sedentary lifestyles. This means they spend a large amount of time sitting, such as at desks for work, watching television, or using electronic devices. When people are sedentary, they burn fewer calories. At the same time, the availability of high - calorie, processed foods has increased. If a person consumes more calories than they burn (due to a lack of physical activity from a sedentary lifestyle), the excess calories are stored as fat. Over time, this can lead to weight gain and, on a larger scale, contribute to the obesity epidemic. Also, a sedentary lifestyle often goes hand in hand with poor dietary choices, creating a cycle that promotes obesity.

Answer:

Question 1

a. Improved cardiovascular health
b. Enhanced muscular strength and endurance
c. Better flexibility and joint health

Question 2

a. Reduced stress and anxiety
b. Improved mood and self - esteem
c. Enhanced cognitive function
d. Better sleep quality

Question 3

An example of a social benefit of physical activity is participating in a team sport (e.g., basketball) which allows individuals to build friendships and develop teamwork skills.

Question 4

In a sedentary society, people are less physically active (burn fewer calories) while often consuming high - calorie foods. The imbalance between calorie intake and expenditure (due to lack of physical activity from sedentary behavior) leads to weight gain, and on a large scale, this contributes to the obesity epidemic.
