This was simple, but the fact is eidetic memory can not be proven outside of mnemonics. By the way there are 3 windows on the back house the one the test presumes I answered incorrectly. The fact that one window is called a double window indicates 2 windows, hence 3 windows on the further house scored 10 out of 10. This was all achieved with out the use of mnemonics. Thanks for the test be more elaborate on your answer or questions. Details in questions are needed for a correct answer. By the test creators standards. In which a test can never be passed because of standards. Thank you have a nice day.
