Diet, Exercise & Lifestyle

Question 1

Which statement correctly describes a benefit of regular exercise for a 12‑year‑old student?

Accepted Answer

It helps the heart pump blood more efficiently, strengthens muscles, and improves mood.

Answer

It has no effect on the body’s energy levels.

Answer

It only helps the muscles but does not affect the heart or mind.

Answer

It makes the heart work harder and can cause fatigue.

Question 2

Lena’s lunch includes a turkey sandwich on whole‑grain bread, carrot sticks, and a glass of orange juice. Which statement best explains how this balanced lunch supplies her body with energy and the nutrients it needs?

Accepted Answer

The whole‑grain bread provides carbohydrates that are broken down quickly for energy, the turkey gives protein for building muscles, and the carrots and orange juice supply vitamins and minerals that help the body use that energy and grow.

Answer

The turkey sandwich gives all the energy Lena needs, so the carrots and orange juice are unnecessary because they only add extra calories.

Answer

The orange juice provides protein and the carrots give the sugar needed for immediate energy; the bread is only filler.

Answer

The whole‑grain bread provides long‑term energy, but because it contains no protein, Lena must eat another protein source later; the carrots and juice are only for flavor.

Question 3

Maya has been smoking cigarettes for a few months. She notices that she gets out of breath faster when playing basketball, she coughs more often, and she sometimes feels dizzy after climbing stairs. Which statement correctly explains why these symptoms happen?

Accepted Answer

The smoke damages the tiny air sacs in her lungs, making it harder for oxygen to enter her blood; with less oxygen the muscles tire quickly, causing shortness of breath and dizziness, and the irritation also triggers coughing.

Answer

Nicotine makes the heart pump blood faster, giving her muscles too much oxygen, which leads to overexertion and a cough.

Answer

Smoking only harms the mouth and throat, so the rest of her body works normally; the cough is just from a cold.

Answer

The tar in cigarettes blocks her digestive system, stopping nutrients from being absorbed, which makes her weak and out of breath.
