Sixteen-Year-Old Denzel Is Complaining About a Lengthy Research Paper His

Sixteen-year-old Denzel is complaining about a lengthy research paper his English teacher has just assigned. "Honestly, I'd like to do a good job on this paper. But the timing is the pits. It's the beginning of baseball season, and the coach is counting on me to be back-up pitcher, so I really need to practice. I'm also trying to get my dad's old car in shape so I can use it when I get my license next month." Denzel's comments best reflect which one of the following principles?

A) Youngsters often need to juggle multiple goals.
B) Many youngsters have a core goal that drives much of what they do.
C) Intrinsic motivation to master academic subject matter tends to decline in adolescence.
D) Teenagers often have difficulty making the transition from elementary school to secondary school.
