Hard one last week! I'd appreciate a confirmation and word play analysis for45ac. Unknown old couple stop and leave bottles hanging together in gardens for collection(10,4).Z?O?O?I?A?P?R?. It must be "zoological park mustn't it?
I have answered this on a previous thread, but am more than happy to repeat.
Your answer is correct; it is a very convoluted clue. My analysis is as follows:
Z (unknown, maths) OO (two 'olds') PARK (leave), bottles (contains) LOGICAL (coherent or hanging together). Zoo obviously is a collection of animals.
