PART III. READING COMPREHENSION (2.0 points)

Read the text below and answer the questions that follow.

Maintaining a healthy lifestyle is essential for teenagers as their bodies and minds are developing rapidly. A balanced lifestyle consists of three fundamental components: a nutritious diet, regular physical exercise, and adequate sleep.

First, your daily meals should include a wide variety of fresh vegetables, ripe fruits, whole grains, and lean meat. You should minimize fast food, fizzy drinks, and snacks rich in artificial sugar because they offer very few vitamins and cause serious dental decay and obesity. Second, engaging in sports such as swimming, jogging, or cycling for at least 30 to 45 minutes a day strengthens your muscles, boosts blood circulation, and releases stress after school.

Finally, teenagers need between 8 and 9 hours of peaceful sleep each night. Staying up late browsing social media or playing online games harms your eyesight, weakens your immune system, and leaves you exhausted the next morning. Remember that healthy habits formed during teenage years will accompany you throughout your entire life.
