We've deduced in our setup that Eberly is on the fourth day. We know that because, according to rules 4, 8 and 7, Eberly has 4 people after him and, according to rule 6, Eberly has 3 people before him, making him have to be in the 4th place.
Brandt, on the other hand, has four people before him. Meaning he cannot be 4th.
Hope that helps! Please let us know if you have any more questions.
