Question

which factor is most likely to contribute to tobacco use?
knowledge of risk factors
desire to look younger
tendency to have low anxiety at home
influence of media on human thinking

Explanation:

• "Knowledge of risk factors" would likely discourage tobacco use as knowing risks makes one aware of harm.
• "Desire to look younger" is not a typical contributor to tobacco use; in fact, tobacco use ages people.
• "Tendency to have low anxiety at home" doesn't directly relate to starting tobacco use; tobacco is often used (falsely) to manage anxiety, but low anxiety at home wouldn't push someone to use tobacco.
• "Influence of media on human thinking" can promote tobacco use through advertising (even if restricted now, historical or certain media portrayals can normalize or encourage it). Media influence can shape perceptions and behaviors, making people more likely to try or use tobacco.

Answer:

D. influence of media on human thinking
