Question

1. if heart disease is a common health problem in your family, which of the following lifestyles should you probably change first as an adult?

○ working out moderately for only thirty minutes four days a week
○ smoking a few cigarettes a day
○ sleeping only seven hours every night
○ drinking alcohol in moderation

Explanation:

To reduce the risk of heart disease, we analyze each option:

• Option A (working out moderately for 30 minutes 4 days a week) is a healthy exercise routine.
• Option B (smoking a few cigarettes a day) is highly harmful as smoking damages blood vessels and increases heart disease risk.
• Option C (sleeping 7 hours nightly) is a normal, healthy sleep duration.
• Option D (drinking alcohol in moderation) is generally considered low - risk for heart health.

So, smoking even a few cigarettes a day is the lifestyle that should be changed first.

Answer:

B. smoking a few cigarettes a day
