Question

which statement describes a substance-free lifestyle?

teeth, gums, skin, and hair all benefit from a substance-free lifestyle.

a life free of alcohol, tobacco, and drugs guarantees personal happiness.

future fertility is decreased by eliminating alcohol, tobacco, and drugs.

when smokers discontinue cigarettes, the health of others around them is not affected.

Explanation:

• For the second option, a substance - free life (no alcohol, tobacco, drugs) doesn't guarantee personal happiness as happiness has many factors.
• The third option is wrong because eliminating alcohol, tobacco, and drugs usually improves future fertility, not decrease it.
• The fourth option is wrong because second - hand smoke affects others, and when smokers stop, others' health is positively affected (so saying it's not affected is wrong).
• The first option is correct: A substance - free lifestyle (no harmful substances like alcohol, tobacco, drugs) promotes better health, and teeth, gums, skin, and hair are parts of the body that benefit from good health.

Answer:

Teeth, gums, skin, and hair all benefit from a substance - free lifestyle.
