The investigative agency has arrested the mastermind and nine other people A, B, C, D, E, F, G, Hand I in this matter. interrogating them, the following facts have been obtained regarding their operation. Initially, the mastermind obtains the correct answer-key. AU the others create their answer-key from one or two people who already possess the same. These people are called his/her "'sources". If the person has two sources. then he/she compares the answer-keys obtained for both sources. If the key to a question from both sources is identical, it is copied, otherwise, it is left blank. If the person has only one source, he/she copies the source's answer into his/her copy. Finally, each person compulsorily replaces one of the answers (not a blank one) with a wrong answer in his/her answer key.
