A rebuttal to "the problem of Sally and Ann"

Sally put a candy in box A and went out of the room. Meanwhile Ann moved it to box B. Which box will Sally open when she comes back? The answer is B because the boxes were made of glass. 
Ann left her pet Charlie in the cage, left its door open and went out. Where is Charlie when Ann comes back? Charlie is fast asleep in the cage. He is a hamster. A biologist told me hamsters are in most cases asleep in the daytime. 
These problems seem at a glance to be purely logical problems. However, these show that the logical answers are not always correct. In most of the exams in Japan, we are required to get the logical answers without being shown the reality. We need the ability to get logical answers. But at the same time we need the ability to ask the biologist when hamsters are awake. 
I do simulations at lab and know how powerless it is. In most cases the simulation results don't correspond with the experimental. I wanted to show you how ridiculous Japanese exams are. Not only logical thinking but also getting the REAL information is important. 
It is ridiculous that we make too much of logical thinking and nothing of real information.
