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" usually reduces tobacco use as awareness of harms discourages it.
• "desire to look younger" is opposite to tobacco use effects (tobacco ages skin), so it's not a contributor.
• "tendency to have low anxiety at home" doesn't relate to tobacco use motivation (tobacco is often used to cope with anxiety, not low anxiety).
• "influence of media on human thinking": Media can promote tobacco (e.g., in past ads, or social norms shown) or normalize it, influencing people to use tobacco.

Answer:

D. influence of media on human thinking
