Answer: The correct answer is: it will be impossible to conduct a double-blind experiment because the kid will know whether he or she used flashcards or the computer.

This with the purpose of obtaining the most accurate answers, since many times people's characteristics or ideas might affect the experiment's development and the results. In the given example, it will be impossible to conduct a double-blind experiment because children (patients) are aware of the method (flashcards or the computer) used to obtain the information.
