There were no correct answers to last week's odd one out. The middle image - of the now-demolished Firestone Factory in London - was the correct answer, as the other two pictures were linked by a water connection. The top building was Park Row House in Leeds by Waterhouse, while the last image was of Bluewater shopping centre.
Better luck next time.
