Which of the following things is a child likely to convince a parent to do?

A) switch to a different political party
B) start reading more literature
C) quit smoking cigarettes
D) learn about new cultures

Quitting smoking is a health-related behavior change that a child could potentially convince a parent to undertake. Changing political parties or reading preferences, on the other hand, are more subjective and unlikely to be influenced by a child. Learning about new cultures may be important, but it is not necessarily something a child would be able to convince a parent to do as it may not be viewed as a priority.
