Zhuang is trying to decide which major he should choose in college. his older brother notes that zhuang is always asking questions, so maybe he should become a scientist. if zhuang asks the same kinds of questions that successful scientists ask, he is probably asking things like
a) why? how do you know? where's your evidence? is there another explanation?
b) how does this affect me? why is it important that i know this?
c) where will i use this information? will it me get ahead in life?
d) who? what? when? where? how? can i get a quote?
