Turn Back Time

Has anyone else picked up on the slightly different directions given in the brief? In one part of the brief, it states that the challenge is to "Recreate illustrations of what different elements of a shopping mall would’ve looked like in medieval times, with materials, aesthetics, and social norms back then." And in the next page states the design brief is to "visually recreate a modern multi-level shopping mall in a cross over between Greek and Indus valley civilization." I will point out that the Indus Valley Civilization thrived in approximately 2000 BCE, the Greek Civilization peaked in 500 BCE, and medieval times started in 500 AD... If the brief allows us to select any time period, it should say so. Anyone else?
