In problem solving, our brain tries to link relevant knowledge to the problem. For example, in below two emoji quizzes, if one had never studied physics before, not likely he/she can answer the question. However, even if you studied physics, is it really easy to guess the answers?
As years passed by, we accumulated more and more knowledge in different aspect. It may not be easy to quick find the most relevant aspect of knowledge in solving a problem.
By the way, how did you do in the quizzes?
