The Independent Mind Olympics

The Independent Culture
Here, as promised, are the answers to our Mind Olympics puzzles, which were set by Chris Maslanka over the three weeks from 22 July to 9 August.

The third week's prize of pounds 100 of Waterstone's book vouchers goes to IL Cochrane of Kirkby Lonsdale, Cumbria, and the grand prize of a 21-volume Macmillan Family Encyclopaedia (worth pounds 525) goes to B Gibbins of Wellingborough, Northamptonshire.

Please note in the following answers that several of the questions admit more than one possible solution. We have not given all of them here. Rest assured that in any case of dubiousness, we have given the solvers the benefit of any doubt.
