Do you know how major universities find out what major new students are destined for?
The put them all in a big room with a schematic diagram of a simple transistor circuit on the board. Then they ask each student, "What is the very first question that comes to your mind when you look at the diagram?"
The students destined to be scientists will ask, "WHY does it work?"
The students destined to be engineers will ask, "HOW does it work?"
The students destined to be businessmen will ask, "How much can we make selling this?"
And the students destined for the liberal-arts will ask, "Dude, can you repeat the question?"
